The device is noise insulation in the panel house. All about the repair of floors in the house How to make floors in a new panel house
Important
It is equally important to take into account the floors of the apartment. I will explain why: if you live on the first floor, then remember, at the bottom of the unheated basement. And this means increased humidity and cold. If you live on the second floor and above, then under you will be a living heard and dry apartment.
Choosing a floor covering, I also recommend to take into account the height of the room. Some technologies simply unrealistic to introduce into an apartment, for example, wooden floors on lags, if the height of the ceilings is 220 cm. Another point is the floor drop between the rooms. We are in all our facilities in the floors in the level.
If in your apartment wooden overlap, then I do not advise pour a concrete tie. There will be a strong load on it. On the contrary, choose a coating that has a small weight, for example laminate or linoleum. Well, it is important to pay attention to aesthetics.
From a practical point of view, I also advise you to choose an outdoor coating on zones. For example, for a kitchen and a bathroom tiles, a tree can be seized into the bedroom, laminate and the like.
Council
Zonail the territory. Separate it with color, it is beautiful and convenient.
Here is how the floors look like zoning:
What is the basis to use
A draft base in the apartment can be done from:
1. Wet screed.
2. Semi-dry screed.
3. Dry screed.
Wet screed
· Prolonged duration of drying. After the fill must pass about 30 days and more for complete solidification.
- In the process of work a lot of dirt.
· The square meter turns out to be a serious load, which can reach up to 70 kg / m 2.
· As moisture evaporates, shrinkage may be observed.
- Requires serious labor costs.
- High strength.
- Comparatively low cost.
· In the screed, you can lay various engineering systems.
· To achieve the required level, you can pour a thick layer without consequences.
Important
Provided that the screed will be at least three people: one on the kneading, the second on the rule, the third on the tray, then on average, you can pour the screed for the working day with an area of \u200b\u200bup to 50 m 2 with a thickness of about 50 mm. At the same time, about the day goes to the installation of beacons.
Work on the pouring of a wet screed costs about 400 p. per m 2.
Semi-dry tie
We use this option on all our objects. You can read more about technology on our second site - http://qualityfloor.ru/
· Dependence on weather conditions. At a minus temperature, perform work is prohibited.
- It is difficult to implement yourself.
· At high speed, excellent quality is preserved.
· After time, cracks do not appear on the surface.
· The likelihood of water leakage is eliminated to the lower room.
· In anything from the wet screed, semi-dry by 15% costs cheaper.
Important! One brigade is a traditional way of filling a semi-dry screed capable of pouring up to 100 m 2. If you use a mechanized method, then up to 300 m 2 per day.
Cost of materials: Cement M500 50 kg - 350 rub., My-made sand 1 m 3 - 1100 rub. The cost of the work in which the work includes the rule and helicopter reaches up to 150 rubles. per m 2.
Dry screed
Disadvantages:
· Hydrophilicity. I explain: if under the dry tie, the pipe breaks, then you will have to make the screed completely, with preliminary disassembly works.
- Cannot be mounted in a shower and bathroom.
Advantages:
- There are no wet processes.
- Noise insulation and thermal insulation increases.
- Ecology.
· Little weight. Three times easier to concrete wet screed.
- After installing the floors are ready for operation.
Important! In one day, a team of qualified specialists can make 50 m 2 dry screed.
The cost of mounting dry screed "Knauf" per m 2 ranges from 450 to 1300 rubles. The price depends on the method of manufacture and volumes. For example, a dry floor screed up to 10 m 2, which includes dry beep and floor element 1000 rub. / M 2. With a similar composition, the volume from 30 m 3 will cost you 450 rubles. I will advise you, compare the proposals at once several construction companies to choose the most favorable price.
Noise insulation
Styrofoam
Advantages:
- Simple installation.
- Easily cut.
- Elastic and strong material.
- Lifetime for up to 25 years.
- No moisture is afraid.
- Flammable material.
· Calle of junctions, which reduces noise insulating properties.
The cost of foam for m 3 thickness of 10 mm - 280 rubles. (I did not find the price of work)
Mineral wool
In my opinion, mineral wool is one of the best building materials that provides excellent floor insulation. However, mineral wool can not be poured concrete. It is suitable only for wooden floors. For example, laying between overlapping beams.
- The ability to absorb sound waves.
- Does not burn.
- Does not highlight harmful and dangerous poisonous gases.
- The ability to cope with the temperature to + 1000 ° C.
- The possibility of laying without the bridge of cold.
- Lifetime for up to 25 years.
- Minvat is resistant to different aggressive environments.
· Throughout the life of the mineral wool saves its properties.
- Parry permeability.
- It is afraid of moisture.
· Difficulties when installing (it is necessary to wear protective overalls).
The cost of mineral wool per pack is different based on its thickness. For example, Minvata with a thickness of 100 mm 600 × 800 mm costs 450 rubles. Minvata 600 mm thick 600 × 100 mm costs 650 rub.
Important! The cost of mounting noise insulation of mineral wool per m 2 will cost 200 rubles.
Ceramzit
If the screed is poured, then in my experience and practice, clamzite is the best solution. Its price is much lower. The price depends on the fraction. It is sold in bags. For example, a fraction of 10-20 mm volume of 0.05 m 3 costs 85 rubles, and fraction up to 5 mm volume of 0.05 m 3 costs 140 rubles.
Important! Cost of filling clay per m 2 60 rub.
Positive sides:
- Low price.
- Natural product - environmental friendliness.
· Does not change its structure when changing the temperature.
- Different microorganisms are harvested in it.
- Refractory material.
- Noise isolation is provided by the porosity of its structure.
Negative sides:
- Because of the porosity is very fragile.
· Because of the low density, it is necessary to float the insulating pillow of a decent height. It is impossible to implement in apartments with small ceilings.
- Ability to absorb moisture.
Insulation
As for the insulation of sex in the apartment, I advise all your customers not to miss this opportunity. Especially when the apartment is located on the first floor and under you the unheated basement. Floor insulation will eliminate thermal losses.
Important
If the warm floor system is stacked on the floor, then the floor insulation is simply necessary. The insulation should have a reflective film. Due to this, all the heat published will rise up the apartment's room.
For insulation, different materials are used.
Polystyrene foam
Polystyoltilol is sold in packages. Depending on the manufacturer, the price varies from 1.1 to 4 thousand rubles. Work per m 2 will cost you 150 rubles.
- Simple installation.
- Small weight.
- Ecology.
- It does not live different microorganisms.
- Does not miss moisture and warmth.
- The service life is 50 years and above.
- Gulf.
- When the temperature is reached, 90 ° is deformed.
Bung
There is a plug roll 2 mm thick - 1200 rubles. 6 mm plug thickness has a roll price - 3800 rubles. In my opinion, the use of this insulation is unreasonable. There are much cheaper insulation. But in some cases this is the only optimal solution. Price of installation for installation - 320 rubles. m 2.
- Long service life.
- Ecology.
- Does not rot, does not spread mold.
- After time, it does not lose its characteristics.
- Passes air.
- Not an easy installation process.
· High price. But as for me, the quality completely pays off at the price.
Ekwata.
One of the modern solutions. In my opinion, the most effective way to insulate the wooden floor in the apartment. Cost 1 kg - 28 rubles. Work for 1M 2 costs 1600 rubles. (wet method). In my opinion, the perfect combination of quality at low cost.
- Passes air.
- Low cost.
· Does not grow mold, does not rot. There are no insects and mice in it.
- Simple installation.
- Seamless insulation.
For your information
Cons: The main disadvantage is that after time, the dry styling of the EcoWhat is glorified. Therefore, insteading the floor, I recommend it to make a good time, on average, 1 m 3 will be a consumption of 50 kg.
Water warm floor
For many customers living in the apartment, I advise you to make a warm water floor. However, it is not always possible to do it. For example, in your apartment low ceilings, and the heating cake can take at least 70 mm. It is not always possible to pour the screed on the water heated floor, because of the weak overlap. It is important to take into account and choosing an outdoor coating. For example, under the laminate, everything is warm and achieved comfortable temperature will be difficult.
Tip! As my practice shows, water warm floor is perfectly combined with ceramic tiles. It has a high level of thermal conductivity, which allows not to delay thermal energy in the body of the screed.
· Lining insulation (what are there any cheaper and better to briefly paint)
Floor materials
The modern market offers a large selection of outdoor finishing materials. I propose to compare the most common facing materials.
Parquet
- Easy when operating.
- Durability of about 100 years.
- Beautiful appearance.
- Ideally combined with any interior style.
· High price. Especially when exotic woods are used.
- From time to time it is necessary to polish.
- When walking, a lot of noise is published.
The cost of a piece parquet is 950 rubles per m 2, and a parquet board from 800 to 2000 rubles / m 2. Work will cost 1000 p. per m 2.
Laminate
There are many laminate manufacturers, respectively, the cost of laminate is different. I'm pushing from class. For the apartment, I advise you to purchase a class of laminate at least 33. So the price per m 2 is located in the area from 300 to 2400 rubles / m 2. Mounting value on average 350 rubles / m 2.
Pluses of laminate:
· Packaging is convenient for transportation and manual carrying.
- Mimics different building materials.
- Easy to care.
- Wear resistance (depends on class).
- Comparatively simple and fast installation.
- Can be laid in different rooms.
· Sustainable to the negative effects of UV, does not fade. Some planks even moisture-resistant.
- Does not breed mold and fungus.
Cons of laminate:
· Unable to restore the upper layer in case of wear. Full replacement is needed.
- When walking, there is a lot of noise.
- Unnatural tactile sensations.
- Rigidity.
· Nallese formaldehydes questioned ecology.
· Without deformation joints, the coating will crawl or swept.
Linoleum
The cost of linoleum varies from 200 to 1.5 thousand rubles / m 2. The value is influenced by its class, for example, commercial, household and so on. For the apartment, I recommend buying linoleum no cheaper than 500 rubles / m 2. Mounting cost: 320 rub. / M 2 glue, no glue 250 rubles / m 2.
- Comparatively inexpensive flooring.
· Resistant to moisture and pair. Actual for premises in an apartment with high humidity, such as a kitchen.
- Wear-resistant (depends on class).
- Simple installation. You can use glue or not.
- Does not slip with cash with moisture.
- Easy to care.
· Linoleum has a specific smell. He passes two weeks later.
- Weak wear resistance to punctures.
- The perfectly smooth surface of the floor is necessary.
Wood
In my opinion, the tree is the most win-win option when finishing the floor in the apartment. Just keep in mind that it is placed on lags. Therefore, the height of the ceilings should allow such a luxury. The cost of the wooden floor per m 2 fluctuates based on the thickness of the board. The average price is 450 rubles per m 2. Flooring boards on lags will cost 400 rubles / m 2.
- Beautiful aesthetic appearance.
- Pleasant tactile sensations when walking.
· Additionally, wooden floors heat the base. You can walk barefoot.
· Easy to use. Once in 5 years is applied with a layer of paint / varnish and floors as new ones.
· On the old wooden floor you can lay a new floor covering.
- Easily repair.
· Mounting difficulties. It is necessary to take into account the many nuances.
- It is unrealistic to achieve perfect floors of the floor.
- In case of non-compliance with the installation technology creak.
Tile
The cost of ceramic tile fluctuates on the basis of its collection. You can find a tile and 400 rubles. / M 2, and there are collections of 17 thousand rubles per / m 2. The cost of work is within 1000 rubles / m 2.
- Solid and reliable coating.
- Does not miss moisture, except that there will be a flood.
- Long operational service life.
- Hygienicity.
- Easy to clean.
- Resistance to temperature differences.
- Resistance to chemical aggressive means.
· High thermal conductivity. Without outdoor heating on the tile, go cold.
- It is traumatic when moisture getting.
- High price.
- Mounting complexity.

Dry key screed in panel houses
Panel houses have their own features related to floors. One of them is the differences between the slabs of the overlap. The height of the differences is very different in many homes. Sometimes it can reach 5-6 cm. Such drops we met several times in panel new buildings. Because of this feature, floor alignment with a dry screed is very popular.
To calculate the material that is needed to align the floor in the apartment of the panel house, you must use a laser level. In order to make an accurate calculation, you can call us and invite our wizard to measure and calculate the cost of a dry turnkey screed. Wireless layer of backfill thickness need to be counted, given the drops of slabs of the overlap,
Polyethylene film is used as vaporizolation. In the case of mounting the dry floor on the first floor, the laying of the film is obligatory. It is necessary to prevent moisture penetration into the backfill and elements of the floor from the basement.
To be between the walls and elements of the floor, the edge ribbon is used. The floor element is pressed against it and does not allow the backfill to dust. The tape prevents the transition of vibrations and deformations from the walls side to the floor. It is possible to use the mounting foam instead of the edge tape.
As an alignment base for a dry screed in the panel house, a grainzit of shallow fraction is used, dry backfilling. For alignment - guides and rule.
Engaged in laying floors since 2010. We try to tell in all details and demonstrate to you how the entire workflow is happening the new floor. On our site you can find a large number of photos of our work and see all the nuances of working with technology.
In the apartment you see in the photos, we made floor alignment in one day. Given the delivery of the material, all the work took 8 hours. From 10 to 18. The amount of material was designed in advance. Our wizard went to the customer.
Dry key screed is the main direction of our work. We try to fulfill our work as quickly and efficiently in order not to delay your repair. At the same time, the cost of our work is transparent and not overestimated.
After completion of the installation work, we leave after the finished floor. Dry screed in the panel house performed. We collected all the garbage, cut off the remnants of the edge ribbon. If necessary, you can begin at least the next day.
If you want to make floor alignment in the apartment in stages: first one room, and after some time another, then when using a dry screed, it is not a problem. The replacement of the floor in the room is happening and you will not even have time to feel discomfort from repair. If you have questions, call us: 8-926-440-98-38. You will be answered by a specialist who works directly with technology and is most qualified in matters related to GVL floors.
Forbidden floors of floors in apartments with laminate, parquet and ceramic tiles
Some of the generalization of the information (Sergey (Shumakov) is my post-post message is not a question!) - Below:
"... a little useful information (to minimally violate the rights of future neighbors from the bottom and side and minimize the likelihood of one of the reasons for conflicts) The fact is that most new buildings give up without elastic 4-20 mm gaskets between the screed and the ceiling (ceiling plate) of the lower neighbor ... And what do you create in old houses - either removing the floors on the lags or instead of the Soviet linoleum laying a laminate-tile-tile -thet and not worth talking. In the livelists and management of Rospotrebnadzor there is enough complaints on experimenters with the ceiling slab of the lower neighbor.
Useful information - below:"... As for the so-called" single-layer "homogeneous floors. (Certain structures of floors with a top layer in the form of laminate, parquet and ceramic tiles - without an elastic laying of 4-10 mm between the tie and slab overlap) ...
Currently, manufacturers testing such structures with laminate / parquet / ceramic tiles in the composition of "single-layer floors" (without elastic gasket between the slab overlap and the tie (concrete or dry ") are not conducted.
Why do not lead manufacturers of laminate, parquet or ceramic tile detailed and complete test protocols of Niizf or other serious expert organization? Therefore, they do not produce, because by the time of the USSR (and abroad), the tests have been established that these types of floors do not meet the minimum requirements for the sounds at the bottom of 7-12 times .. and what is the point of manufacturers of laminate / parquet / ceramic tiles spend money on tests that show the inconsistency of their materials minimal Requirements. Never came across for many years the protocols of testing of such floors. For example, in usually conduct such tests in apartment buildings Institute of Construction Physics (Niizf Raasn) ..
But sometimes in the press in addition to the will of manufacturersthe negative test results of their materials in apartment buildings appear "mediated" negative test results.
That's more recently: article "The neighbor can be given under the court", "Evening Moscow" №125 (25640) of 11.07.2011.I will give an excerpt from there, written in the results of the tests of the sexes common in Russia
Valery Angelov, head. Soundproofing sector and enclosing structures of the building Research Institute of Construction Physics:
"... Usually, tenants are preventing the top neighbor. This is due to the impairment of sound insulation. The fact is that in the social housing of the apartment are handled with linoleum, which is taken into account when calculating sound insulation. The sound absorption of linoleum is up to 18 dB, and the parquet and laminate - 8- 12 dB. If residents change the linoleum on parquet or laminate, sound insulation is broken, and the neighbor bottom starts to hear at the top every sound.
And monolithic buildings give up at all without finishing. When the owners make repairs, they are from the savings of the floor flooring immediately by the screed, and this is not enough ....... "And what is translated into a simple tongue meaning these figures 8-12 dB? Translate:
Take the latest regulatory building AC 51.13330.2011 (updated editorial board 23-03-2003 "Protection against noise and acoustics", mandatory for any repairs and works in an apartment building. They provide a mandatory parameter when testing (after reworking or creating) floors - the reduced level of shock noise In the lower room, - a maximum of 60 dB!
And, for example, this indicator, in the apartment, the ceiling of which consists of common (more than 80% of houses) and in Russia of multi-console plates 220-mm or 16-18 cm monolithic can be found in the estimated samples of 1977 ("noise protection)" - 80 dB (easily downloaded from a heap of sites this SNIP). .... This refers to the "naked" plate of overlapping or stove with a tie of concrete. But you will advise you to simplify a popularly written and useful article of the Novosibirsk company (link - SIBAMT. RU / MATERIAL /
"Soundproofing in residential buildings. Problems and solutions"
(There will find a lot of practical and useful information):
There, in the Test Test Table (Table 2.1) will also see this figure - that the slab 220 mm overlap with the screed has this styling for such plates - 80 dB. And so that the neighbor does not take from below in the worst version of the patient of the neurologist, referred to how much? We consider:
We take away from 80 dB in the apartment under the 220-mm multi-console or monolithic slab, those 8-12 dB, which gives in the ideal case the so-called "substrate under the laminate" (see the external tests from the employee Niizf) - get 68-72 dB .. That is, the minimum required 60 dB lacks from 8 to 12 dB. In the homes of the Soviet times, the level of noise from the walking-blows immediately with the floors is more or less brought to almost the minimum norm of the average thick linoleum (which will also see from this article and test tables) ... But what will your neighbor will take an interest on top This issue ...
That is, for single-layer floors of floors with a laminate or a parquet of noise in the lower apartment will be 7-11 times (missing 8-12 dB, translated into "times" intensity) so that the neighbor is at least I did not hear your walking in the slipper and moderately heard the running Children ..-!On "prohibited" structures from ceramic tiles:
"... The reinforced concrete plate of overlapping 140 mm thick without coating has an index of the reduced level of shock noise near LW, N \u003d 80 dB. Unlike the" missing "to the norm in the case of air noise of the pair-triple decibel, there is a difference with the maximum permissible value. (LW, N \u003d 60 dB for category B) is as many as 20 dB. This approximately corresponds to the case when a neighbor topped to the ceramic tile. At the same time, absolutely all movements are heard in the lower room. And if in the previous publication speech It was about the fact that existing sanitary standards and the concept of acoustic comfort - things located far enough from each other, what can I say in this case? ... "Acoustic. RU / REF_BOOK / ARTICLE ... / OVERLAPS /
Soundproofing of inter-storey floors, noise insulation of rooms
"Building Technologies", №5 2002)And now from the answer to the sound insulation and acoustic forum of a specialist Soundproofing of the famous acoustics engineer A. Bognika:
"... laying a ceramic tile on the" naked "(i.e. without sound insulation)) the design of the overlap is really the worst option. If an aligning screed was left on the floor slab without any gasket (which, of course, theoretical assumption ) It would be better from the point of view of the insulation of the shock noise. When you hit the screed, the top layer of cement turns into dust that begins to play the role of the laying layer. (This is well noticeable when testing in the audio chamber, when the impact machine is long beating The same place "naked" slab overlap after a while it becomes heard somewhat quieter).
Durable and rigid ceramic tile does not shock anything, therefore, those 20 dB differences between the minimum requirements of the SNiP and the actual value of the level of impact noise in the absence of the zi-design of the floor and the laid tile become distinctly and frightening.
At the same time, shock noise is well heard in adjacent rooms, if such a tile is made not in the room from above, and the corridor on top and side. And of course, this is a big problem, because the life in the apartment is becoming nervous and not comfortable ... "( from the site - Forum Acousti. RU - AcousticGroup Firm)Therefore, such structures of the floors are not intended (and formally legally prohibited under the conditions of testing) in apartment buildings. But since for this there is no sanction in the form of a fine and the state in the 90s let the control of the control - they themselves understand ...
So ... if such floors (more precisely - the design of single-layer interhesive floors) are not even calculated on the walking in slippers or movement of the chairs - what to talk about the running of the kids!(Yes, I forgot to remind - huge numbers - "15-19 dB" - on packages with a "carved" substrate under parquet laminate (if you think and learn the truth - refers to the results of the tests of thicker pads and usually under heavy (!) Scientific. However, on the topic of real terms in dB on rolls of 1.5-2 mm substrate under laminate or parquet to completely different designs and completely different thicknesses of gaskets, only lazy acoustics did not write.
However, you can try to get the miners from the sellers or from the manufacturer (letter to the site) of sex testing protocol (laminate or parquet) on a sold substrate. I think you will have the same result as I am silence in response ....
So as an additional action upon receipt of an apartment apartment, I advise you to find out what type of gender is going to make your neighbor from above ... .. and agree! Then - almost impossible or expensive to fix ...
Otherwise, especially if you have a working person who at night before working in the afternoon, you have to sleep, you can "get" into the uncomfortable situation (for example, small children children and or some categories of non-working and "wrong" floors upstairs or side by wall)[Good luck to you in choosing an apartment and the "right" neighbors of neighbors and success in conducting the "right" repair!
To be continued...
And the consequences of the shock noise and "not recommended" floors of apartment buildings are manifested in the form of the effect of a multi-head "Snake Gorynych": "Drinks one head, and all the rest suffer from the hangover ..". Explanation: The shock noise "Antisoyed" property: due to resonances of overlaps, walls and rooms, the shock sound is weakened slightly, transmitting several floors up and down and horizontally (according to the terminology of acoustics - "structural" transmission of sounds.). And the sound is emissors allthe surfaces of the neighbors are not just some single wall or ceiling. Lowered "casually" chair on "not the right" floor after 23.00 - the sounds of "impact" will increase and come to all near neighbors. And if the next neighbor has been made by "sound conductive" floors, then little weakening, it will come to more distant neighbors (as "fire on the path of gasoline"). This is the "harmful" property of the tile (at the parquet laminate less) - "Small inner attenuation".
Myths about carpets.
On the site question (claims of neighbors from the bottom after laying on their ceiling tiles in the corridor and the kitchen): "And if I put a carpet cover on the tile?" A response of an acoustical specialist: "If you put a carpet under the tile, then the effect of reducing shock noise for neighbors would be noticeable. No humor - long-known professional acoustics engineers System property: "Concrete slab-tie-tile" \u003d Resonant audio gain on 1-2 frequencies of the audible range. For example, the sounds of the moving chairs are "audible" by the neighbors on the side, below. And cheap with rigid (non-ruby) base. The carpet will only reduce the part of the "vertical" "strikes" (for example, "Topot" of a child or drop items) - the resulting "resonant system" can not be eliminated.
But horizontal (the chair moving, for example) weaken enough. If, under the carpet on the "wrong" floor, there is also a cheap 3 mm foam (isolon, polyethylene foam, etc.) - then the harm to neighboring health will decrease half. The resonance effects have not disappeared by the project, but the number of neighbors will decrease, to which the sounds reach (like fire on the "track" from gasoline), and the power of the sound - the probability of wake up the neighbor, to which the sound "bridge" of the wrong sex "impact sounds. (For a toilet, where in waterproofing and sanitary considerations, as an exception, the SNIP is allowed cheap rubber mats).
There is a cartoon where the bear is trying to get into the house built by small animals ... But here the house is not designed for him ... and apartments with "leveling (draft) tie" are not calculated on the design sound insulation, to put something other than that tissue (4-5 mm) Linoleum (with a lower layer of foamed material) or parquet (laminate) in compliance with all technological soundproofing requirements (or "floating" floor).
About sleep and "night" sounds
"... For awakening, those discrete components play a decisive role, the level of which is more than 10 dB exceeds the average noise level ........." ("Technical Acoustics Handbook". Under. Ed. M. Hekla and H. A. Muller, p. 106) - the situation when the volume of sound during sleep, albeit briefly, increases 3 times (\u003d 10 dB) in comparison with the permissible night background level. More: ".. Make a dream to superficial or wake sleeping. Sudden short-term noises are particularly disturbed, such as shocking doors, shots, bark dogs and so on, the level of which exceeds the noise background by more than 10-15 dB.”("Science and Life" №4.2006 p. 82.)
“.... We have not yet effective methods to shorten sleep without harm to health .... So weded made such an observation - the number of traffic accidents in Monday is sharply increasing, and all because on Sunday get up and lies later than usual ....”
Director of the Somnological Center of the Ministry of Health of the Russian Federation Professor Ya. Levin
Article "How much to sleep ..." Komsomolskaya Pravda "March 25, 2009 ... required for the full restoration of the body (according to the World Health Organization). It's clear that 43% Population - required 8 or more sleep clock, and 23.5% - more than 9 hours.
About accessible ways.
"By default," builders are assumed to be the duty of the united to bring sound insulation to the norm (at least-not to worsen) and do not commit excessive drums and other noise actions, for the suppression of which typical projects of apartments are not calculated.
But after all, there are accessible ways to reduce harm, unconsciously and not specifically caused by neighbors, for example:
1. Free:
- do not shut the door to the latch, but carefully close;
- do not "bang" indoor and balcony doors;
- to finish "noisy-shock" events (washing) in the noisy (on the project - "with the" sound-winning "floors from the tile) of the apartment - wanted) if possible (!) To 23.00 nights;
- in rooms with such sexes, if possible, not "stupid" and not drink sneakers with hard heels,
- omit - move the furniture (chairs, layout of sofas) "slow and sad", etc.
- pieces of the rubber seal, which seal windows ("E" -pille-thinner or "p" or "d" -potasche) around the perimeter of doors in the apartment, if young children or the elderly or in a capitution, do not always control their actions "clapping" do door;
- felt (rubber) packing on the legs of chairs;
- cheap carpet (and even more effective, under it-cheap 3 mm foam) in those places where the furniture (after 23.00) is moving on the "sounding" furniture (chairs), a sofa is unfolded, etc.
- A rug in a room with a "sound-drying" floor in a place where after 23.00 Cabinets of the hostess, etc.

At one time, when there was no Internet, but was in my apartment the problem of sounds from the elevator - I "dependent" and in our regional scientific library (and in the pair of scientific libraries of Russian cities - on vacation) and for me the studied "content" of sections Construction textbooks (available in scientific (!) Regional (!) Library) It turned out an interesting thing:
The topic of "sound absorption" (and not even sound insulation!) Touch the maximum of ten pages only in the course "Building materials."Of course, there were" in stock "in the repositories of libraries and textbooks, for example, the Kovrigina" Architectural and construction acoustics "or the benefits of the Soviet acoustics of Creotan or Lvov .. But ... as I understood - theater of acoustics (and even more so-" sound insulation of fencing constructions "as an independent course (at least one on the semester!) Is studying unless in non-construction universities (aviation, shipbuilding, radio engineering or some more specialization) and then - in the framework of graduation specialization or optional. In general, I concluded that With the exception of a good regulatory document (SNIPA 1977) and a pair of five regulatory and non-normal documents in its development in detail in training future builders, this topic is not brought ... (the most important importance in training is the development of the builder or architect knowledge about strength ( Sustainability) of structures and calculations of their or information on structures and materials providing thermal regimes ... and the course of study is limited to 5 years.
Another thing is that by virtue of the state construction mechanism in the USSR typical ( recommended) Floor designs (as component parts of the house projects) were required when delivered .. (that is, really future builders engineers or architects did not need knowledge of these materials - "there is a project, where intelligent people from the center have taken into account and all permissions received" ..) And these typical constructs in the projects of the USSR times naturally corresponded to the minimum requirements for interconnecting sound insulation to the residential buildings of the category "in" (smallest comfort) .. (well, maybe with the exception of some experimental series) I just remind you that I am He lived in different types of houses built in the 60s and 70s (and panel and brick) but! Even in the student (!) Hostel and in the municipal panel hostel, I did not feel the "presence" of the neighbors from above or on top of the side (speech about impact noise) - that something heavy, such as a chair or a "drunken body" will fall from above. Whether the case is when my neighbors from above from your ceiling (!) (The last (!) Floor) heard the baby's child from below (my side neighbors) running on the floor from the "tile tiles" (a large lounge lounge in 4-room my Side neighbors ... And I heard, respectively, how I needed on the same tiled floor "swept" the cat's cat .. (When, when behind the wall in Polkirpich, the granddaughter of a neighbor or a neighbor for the "wrong" parquet floor shifts something - the identity of hearing.
And why - in all these houses (the projects of the USSR times) at the upper neighbors were the project floors "on lags" (one of the structures that reduce typical household shock noises before intimidability.
Note: Perhaps, since I do not have experience in communicating with teachers of construction or architectural universities, it is not so right. And my conclusions about the absence of a detailed course (semester, section) of study on the "sound insulation of the enclosing structures and residential buildings" were erroneous ...

NOVATION: the legal aspect of the "prohibited" structures of the floors (interlaced interlated) actively began to understand (up to requests in Minstroy and the prosecutor's office, not to mention the non-less than several years of work (complaints) in the residential inspection) on the popular forum "CLUB OF CLUB OF SIDES . "
I went after a long break on this good site and ...
By clicking on the left of this forum on the left of the "Recent Posts" to see at least two of the top ten (latest discussions) for August The results of attempts since 2013 and through the prosecutor's office and through the livelihood and through Minstroy Russia to begin the procedure for changing the practice of legislation and the wording in part of self with the device of floors.
Either through the recognition of the most part of the floor, as it were, "common property" (once there is a breakage of several apartments on the brain in brains. So through attempts to introduce into a technical partition that disappeared in the 80s-90s. ..
In general, it obviously got people the self-government of the upper neighbors with a stove of them (!) Ceiling.
And while the lousy will pass this stage - it is difficult to hope for a universal and current outcome.
Read yourself, I gave a link, how to get to this useful presentation of the material on the website "Forum" on the "Forbidden Polits" in an unusual perspective.
..Very informative text with descriptions and full calculations and answers from BTI (and Rostekhinventarization) and the Ministry of Instruction of the Russian Federation and the prosecutor's office.
And calculations (not all) from technical and technical and legal regulations on the flooring ..
(Interestingly, for example, read exposure response from one of the administrative bodies in the spirit ".. How do you imagine - how we will to determine the design of the floor to remove the plinths and ….”)
The main thing is that this path is laid .. The first and most inefficient stage(work with administrative instances, and not with judicial - Armed Forces) passed ...
Maybe the chela (under PRAKTIK and the other) is still on the standard path to go - the second often the resulting stage will be held .. ways to standard and typical for obtaining the result that many have already passed ... in R. g. ("Russian newspaper") Often very small font print the decisions of the Russian Armed Forces of the Russian Federation on the recognition of certain formulations of technical and legal acts inherent in general or acting in a different sense, which was previously recognized by the authority.
- Appeal to the world, regional (republican) - in order to "admit ...." or "force ...." (to fill the Count of the TECH Sportsport BTI (Rostekhinventarization) of their region. (And the standard appeal in the Armed Forces of the Russian Federation is the procedure or direct challenge of the two or three acts of technical and legal on the list of actions recognized by redevelopment or (s) to fill the graph in the process of full construct. floors .. (or in order of supervision on the decisions of the lowercoming (world or regional ships)
- Appeal in the Armed Forces of the Russian Federation directly by correction
("Recognition is not relevant ...... In the sense, in which it does not imply under redevelopment, the change in the design (composition) of the floor, including ............."
AND
"...... recognition in inappropriate (invalid) in the sense, in which it is not implied to the suggestion of the description of the design of the floor with the inclusion of the characteristics of heat-freeze-insulating (elastic) layers”
Something like such decisions and the wording often endures the Armed Forces of the Russian Federation ... and in its competence, the judicial interpretation of the government decree, which determines certain types of actions, while specifically recognized by the redevelopment .... And in his competence (Supreme Court of the Russian Federation), the judicial interpretation of the deposit inventory (compulsory aiming in the Count Counts of the Total Floor Design) and the Government in order and methods of inventory (making data and the form of a technical support) on the need to make the floor design to the technical support (and in accordance with Acting The wording of the LCD of the Russian Federation and the technical norms of the use of housing allowing to recognize the change in the floor of the Floor Reference) if it is impossible to go directly - there is no fine in the COAP of the Russian Federation for the violation of the construction rules in general, and it is unlikely to appear - then you can search for others. Go to a completely reasonable way of recognition and changes in the form of a specific and unambiguous formulation in the Government Decree - No in the Administrative Code of the Russian Federation, a fine for violation of SNIPs and the joint venture at all - only in cases where the breakdown of death or other severe consequences entailed ...
While it is present only in the form of the Snip (SP) requirement without a fine in the Administrative Code of the Russian Federation) .. There are enough such acts. The prohibition (or direct or indirect-in the form of the requirement) is, but no punishment ... With our usual and some legal .. Yes ... nihilism, the levels of income of most Russians may be the absence of such a fine and reasonable ...
Opinion: In my opinion, it is unlikely what the person from the forum is crossed - a change in the LCD of the Russian Federation and the Government's decision on the composition of the general property - by the recognition of "common property" "Interlated overlap, including a mandatory elastic layer in the structure of the floor .." or "Interlated overlap and floor, without finishing (upper) floor layer" .. Something is necessary for the help of the aesthetic tastes of residents to leave. But what the hell is not joking - maybe people and this will achieve through the deputies of the State Duma and other lobbyists ...
Having achieved the decision of the Armed Forces of the Russian Federation that the fencing structures (slabs) of the balconies are the common property of the owners of the house .. (Definition of the Supreme Court of the Russian Federation dated January 17, 2012 No. No.
Note(On the typical position of administrative authorities):
A couple of years ago, even the most advanced inspection (GGG Moscow) was limited in response to the statements by Muscovites to "prohibited structures of floors at the top" answers, such as.
"In the design of the floor over residential premises, there should be an elastic gasket ..." ignoring for example, explanations in ST SEV for impact noise and in our LDIFECs and about accounting for the need for a change and accounting Diagonal ( Taki are of interest. Here is an example of the most loyal response to the site GGG. Moscow from 2011
Question: Good afternoon. The house of the series P-3M 1998. On the slab overlap lay foamed linoleum. It was quiet. Now the neighbors floor above replaced it to a parquet, which was put through Phaneur, while the sound insulation was not performed. . We have become noisy. Learners steps, movements of items. Heard when the small object falls. Is this a violation? How to be in this situation? Can the inspection assign float examination. Or need to contact the court with a request to appoint an examination.
Answer:
The examination requires grounds, that is, confirmation of the fact that the noise level in your apartment exceeds the permissible values. You can invite a licensed organization that will measure noise from any sources in day and night. In difficult cases, when the noise effect is inconstant or randomly unpredictable, it is possible to install a noise recorder fixing the change in any area of \u200b\u200bthe sound spectrum. According to the results of research, a report is drawn up with measurement data, as well as recommendations to eliminate the sources of noise effect. However, to establish the cause of exceeding the permissible level of noise, access to the supervised apartment and the consent of the neighbors to the opening of the floor is necessary. Disruption is an inconsistent change in the structure of the floor. In case of refusal to access, the question can be resolved through the court. If you contact in the prescribed manner in the Moszhilospect, your appeal will be considered, and necessary measures will be taken. However, it should be noted that the Moszhiliospectoration does not pay for measuring the noise level.
And below - another, too, a typical answer GGG Moscow from 2011 (less loyal in relation to the lower neighbors of self-servers with their ceiling slab) ..
Question: Hello! Can you please tell me how the apartment is checked for redevelopment of the floors? And how is the "redevelopment of the floors" from the "Replacing Floor Cover"? Thank you.
Answer:
Floor design includes several layers:
- The foundation
- Heat insulation
- Soundproofing
- Screed
- top (finishing) coating
Depending on the number of layers, the floors may be single-layer and multi-layered. The number of floor layers, as a rule, depends on the purpose of the premises.
Single-layer floors from an acoustic point of view do not apply.
To replace the flooring of the floor, the project and permission is not required. Violation is unauthorized change in floor design.
Replacing the floor design is performed by the project.And on the basis of the permission of Moszhiliuspect. Soundproofing from porous elastic material for residential premises is required.The project of the flooring device includes floors of floors, the layout of the flooring, the floor waterproofing scheme.
The project requires an agreement on the author's supervision.
In the process of work, it is necessary to compile acts of examination of hidden work.
The activation of hidden works is made with the participation of the representative of the project organization, the customer, the manufacturer of works and the representative of the owner.
Acts for hidden work must be compiled immediately after their end, if in the future construction during the construction, this type of work or structures should be hidden.
In the case of work, the act can be drawn up with the participation of representatives of the management company, the housing and operational organization and the owner of the premises.
According to the regulation of the design and holding of reorganization and (or) redevelopment of residential and non-residential premises in residential buildings in the city of Moscow (Resolution of the Moscow Government of September 25, 2007 N 831-PP "On Amendments to Amendments and Additions to the Resolution of the Government of Moscow on February 8, 2005 N 73-PP "), in the absence of acts on hidden work, the inspection has the right to require a selective opening of the designs of the controlled object in order to verify the quality of the layers in multilayer structures, the correctness of filling the seams, the devices of the joints, etc.
The requirements for the structures of the floor are set out in regulatory documents: SNiP 2.03.13-88. Floors; SNiP 3.04.01-87. Insulating and finishing coatings "SNIP II-12-77. Protection against noise;" MDS 31-11.2007. Flooring device ";" Floors ". Technical requirements and rules of design, devices, acceptance, operation and repair (in development SNiP 2.03.13-88" Floors "and SNiP 3.04.01-87" Insulating and finishing coatings "), recommendations for Floor Device (in Development Snip 3.04.01-87 "Insulating and Finishing Coatings"), "Recommendations for Floor Device" Developed by the Separation Department of the TsNIipromzda JSC in the development of SNiP 3.04.01-87 "Waterproofing and finishing coatings", section 4 " Device flooring ", etc.
Since there is a response from 2011. From the state leisure inspection of Moscow, the wording, hiding behind which some lower workers who do not have, probably in the upper neighbors of the "prohibited floors" covered and covered with unsubsions on complaints of self-sufficients from above.
Note: Approx 2012 on the website of Gezh, Moscow disappeared the rubric "Answers" in the forum genre. Therefore, I can not say anything about the politics of this supervisory authority at the moment ...
The update or replacement of the old, worn floor in the apartment is one of the most time-consuming operations in the overall repair process. Only submitting all the scale and cost of the upcoming, many housing owners very often refuse to repair floors, limited to changing decorative coverage on them. But the time takes its own, and sooner or later the moment comes when it becomes simply impossible to delay such work.
In this case, it is not necessary to immediately look for the brigade of the masters - especially since in a similar area of \u200b\u200bservices, you can very often meet the frank "Khalshchikov". As a result, everything can pour out in a completely unnecessary spending of time, nerves and money at a low-quality result. Why not try to do it yourself? If the owner has certain skills in general construction works, and if we hold in the apartment with your own hands in stages, with compliance with the recommended technological rules, then everything should work out!
Stages of repair certainly depend on the type of flooring, their original state, the purpose of the premises in which work is underway, such as the finish coating. This publication will consider several most common options.
Starting Stage - Decide on the front of the work
Once the owner of the apartment wondered about the repair of the floor, then, most likely, on that there are motivated reasons, unless, of course, this is not a cosmetic replacement of the coverage in the next whisper of the spouse. Therefore, first need to identify and clearly formulate problems - all the scale of further preparatory and repair work will depend on it.
This publication is about the urban apartment, and in the overwhelming majority of multi-storey houses, any gender has the basis in the form of a reinforced concrete slab overlap. But the further design can already be significantly different. The floor can be arranged on the lags fixed to the base, or be imposed directly on the concrete tie.
- The wooden floor on the lags, its defects usually begins to show the screech, the instereability of the coating - the flooring "play" under the legs, the appearance of an unpleasant smell of rot, education and gradual expansion of the gaps. Even worse, if suddenly one of the boards cracks or her fragment falls down.
Old wooden floor reminds itself with a creak and "playing" boards - The old screed on which the coverage is used, from "old age" can also begin to preserve surprises, especially if it was once filled with low quality. Thus, the emergence of obvious creaks and rustling from sand or small pebbles, "Creation" of the screed, the occurrence of the washing sections of the surface, the inclusive instability of the whole major fragment is also not excluded.
In any case, with explicit defects, remove the old coating.
Removal of old coating
- From the room you will need to make all the furniture, completely freeing it for further work. If the repair is not carried out in the entire apartment immediately, but from the room to the room, it will be necessary to provide protection against dust propagation, for example, waking up the inlet of a tight polyethylene film or often moistened tissue, and a gap under the door with a roller with a wet rag under the door. True, the full effectiveness of this method is very doubtful, and the best option is still - to provide for the removal of family members at the time of repair behavior. Nevertheless, the barrier for dust is necessary in any case.
- Next, old plinths are removed. Do it carefully so as not to damage the bottom of the walls to which they are attached. If the plinth is supposed to be used, then they are numbered at the location and temporarily remove.
If anyone before with this business did not come across, then you can recall - the plinths are attached to the wall, and not to the surface of the floor, that is, you need to correctly direct the arm of the lever. It will be easier if the plinth is fixed on the self-tapping screw or on special brackets.
The next step is actually removing the old coating. Several options are possible here:
BUT. If the floor is staminated by some rolled material, then it is attached to one of the sides and try to accurately roll into the roll - it will be easier to carry it out. In the event that the coating (for example, linoleum or carpet) once laid without glue, directly on the concrete screed, make it easy. It is possible to first, to facilitate action, to make parallel cuts with a sharp construction knife, thereby separating the entire cloth into several narrower tapes.
But often there are situations in which the old material is moving together with the layers of the detached screed. Then you will have to remove it fragmentary and immediately endure out of the room together with pieces of concrete so that this construction garbage does not interfere with further work.
It happens that once a qualitatively glued linoleum when removing himself begins to settle down, leaving the suction films on the screed. In this case, you will have to work as a scraper (spatula), warming these sections with a construction dryer or moisturizing the old glue layer with a solution of detergent for floors.
B. More trouble can deliver the old "playing" parquet. If it does not represent value, then its dies are consistently removed, immediately loaded into bags that endure as well. If once the parquet was glued to bitumen mastic or glue on an organic basis, then the removal of individual dies or even integer fragments can be difficult. "Recipe" is the same - a scraper, chisel and heating with a hair dryer.
IN. To remove the old tile, it is the most convenient to use the perforator switched to the loafing mode with a chisel-blade installed. If there is no such tool at the disposal, then everything is performed manually using the hammer and chisel.
G.When removing the boarding of the floor, the most complicated, probably pick up and separate the first floor. Further when you can get a free lever, work will go faster. You will need a nail-pressure with a long handle-lever, hammer, ticks. Nails must be treated to remove carefully, without destroying the boards, as it is possible, this material will still serve for a new flooring after repairing or for the manufacture of lag.
If the old coating is mounted with screws (self-tapping), then you can try to dismantle it and with a screwdriver.
Well, if the boarding coating is already no value, it will be most convenient to make cuts (carefully and prudently and prudently, so as not to hook a concrete base, do not damage the lags and not "dig" on a nail). After such separation of long floorings, their removal will become an easy task.
Is it worth removing all the boarding floor covering, if the explicit defects were observed only in some sections, and the plans should not be replaced on another type of surface finish? Of course, it can be limited to only partial repairs - the replacement of wear or spoiled parts. But specialists in one voice advise - remove everything completely. There is no guarantee that if the process of the scene manifested itself in one field of the floor, he will not show himself in another after a year, or even earlier. It will not be cheaper to render the basis and rearrange the floor, even if it is used to return to this repair again after some short period.
Conducting the reserves
After the floor covering is removed, it is necessary to carefully examine the base.
- If lags remained on the floor, and it is planned to fire a milking coating again, then you should carefully check the condition of these carrier elements and the backups to which they are installed. Brussia Lag should not have places of decomposition, drumsiness, mushroom damage - such details are subject to mandatory replacement. Every loggment is checked under load - it should not hang out, fuse, creak, etc. If necessary, the linings are updated that hold the guide at the desired height.
If the state of the lag does not cause concerns, then after conducting thorough cleaning in spaces between them you can install a new coating. It is possible for this, most of the old floorings are quite suitable. After such a bulkhead, the floor will cease to creak and acquire the necessary stability. If required, there is a thermal insulating material between the lags, which will also take on the role of a noise insulator.
However, on the old wooden floor, very often the lags themselves are quite worn, and their repair is impossible or does not guarantee durability. In this case, they will have to be dismantled to subsequently install new ones. When removing the lag, it should be remembered that they can be firmly attached to the base base. It is necessary to show accuracy and diligence to prevent strong destruction of the concrete basis and do not add excess worries to restore it.
After removal of the lag, the most thorough cleaning of the base of the floor is carried out so that you can move to further stages.
In the case when, after removing the old finishing coating, a concrete screed opens under it, it is examined in the most thorough way. It is necessary to rely that concrete is strong in itself, and repairing such a surface is optional.
The screed must be tagged - it will help to identify areas of its detachment, which are to be removed to the "healthy" base. The surface is checked for the presence of loose places, where, due to the violation of the filling technology, the solution did not scroll the strength or has been erosion due to the impact of moisture. Such sections also require cleaned.
Do not leave on the surface of large slots - from here, the process of destructuring the base may continue. The slots and cracks lie down with the cutting of the stitch and deep into at least 10-15 mm, for subsequent repair.
Sometimes after removal of unstable sections of concrete, an unsightly painting opens, such, for example, as shown in the photo. However, it is quite amenable to repair.
After removing defective sections and cutting cracks, careful cleaning is carried out. It is best to use a powerful building vacuum cleaner in this business - other means to clean the surface and the formed cavity from small garbage and dust is extremely difficult.
Sometimes you have to resort to a complete dismantling of the entire screed to the slab overlap. This can be caused by extremely low quality, coatings that are inappropriate to repair, and it is better to restart completely. Often in the screed in raw rooms finds the "refuge" mold or fungus. Another option is when the floors require additional insulation and noise insulation, and the height of the ceilings and the dimensions of the doorways in the apartment will not allow to raise the level of the coating (taking into account the thermal insulating layer and finishing). To the same extent resorted when it is planned to make the wooden floor on the lags instead of thin coatings.
Complex, but, often, simply necessary operation - Full removal of old screed Of course, the process of completely dismantling the screed with the help of a jackhamper is very tedious, noisy and dusty, but no other way is not invented. This requires certain caution in order not to damage the concrete slab overlap. The screed is cleaned with separate slices that immediately dig up toward the shovel and pack over the bags for the export. Use even small fragments as a material to fill a new solution - not recommended, as they do not enhance, but on the contrary, the quality will worsen.
After removing the old screed, a thorough cleaning of the surface is carried out - as it was described above.
Basic surface repair
What was the floor was not planned further to the flooring, the concrete base for it is necessary to put in order. Thus, poorly sealed seams can be expounded between the slabs of the overlap, the slots around the perimeter of the walls, potholes or cavities, etc.
Such a repair is necessary even if the fill of the new solution may not penetrate these flaws, there will remain air cavities that reduce the monolith of the coating and the starting point of the screed destruction process. Especially this is important and necessarily if the screed will be poured onto the separating layer or on the waterproofing film (floating screed).
All surface defects need to be carefully cleaned, if necessary (for example, interchange seams), to be separated, and then remove even the smallest crumb and dust with a vacuum cleaner.
The next step is thoroughly, at least twice, which is designed specifically for concrete.
Such treatment will significantly strengthen the surface, which is especially important in its loosenness, increase hydrophobic qualities, reduce the absorption of concrete, will improve adhesion with repairs. Further work is transferred after the last applied layer of the soil is completely absorbed and dried.
As a repair composition, a conventional cement-sandy solution can be used. However, it will dry and gaining the necessary strength, it is long enough, and it is better not to regret money on special repair formulations, also on cement or epoxy basis.
The printed flaws of the surfaces are maximally fill in the repair makeup, comparing with the overall level of the floor. To do this, you can use the usual spatula. Some remodes are implemented in plastic tubes, and it will be more convenient to apply them using a construction syringe or a special "gun".
If the defect is large in volume, then in some cases it can be resorted to its filling foam. After its drying, the surplus is cut off, and then the remission is adjusted to the total surface level.
Repair "twists" give time for full frost, in accordance with their instructions, after which you can fill the surface using sandpaper, wrapped on the bar. Then it is recommended to go through the entire surface of the primer again. If in places of repair marks an increased absorption of the composition, then these sites are so ground twice.
After drying the soil, the surface can be considered ready for further work.
Aligning screed
If the old screed or wooden floor was shot, and the slab opened, then, most likely, its level is very far from the horizontal. The house eventually gave a shrinkage, and when it was erected, many years ago, builders could not particularly take care of the strictly verified level of overlaps. So, what floor was not planned to do next, it is recommended to be the basis and strengthen, and at the same time align the screed. The thickness of this flooded layer should be at the highest point of at least 30 mm
First of all, it is necessary to determine the value of the difference, that is, to identify the peak, the highest and lowest surface point and "breaking" the zero line line. At this mark will be an exhibited a system of beacons.
To fill the screed, you can apply a conventional cement-sandy solution that is preparing directly at the place of work. Usually proceed from the proportion of three parts of the sand to one cement M-400 - this ratio gives the optimal surface and wear resistance to the surface on which then can be mounted any of their existing floor coatings.
Those novice builders who do not want to communicate with independent preparation of proportions can be recommended to take advantage of ready-made construction dry mixtures. Their composition is already optimized under the screed, and it remains only to set it out correctly, in accordance with the attached instructions.
What is the result of materials in a matter of or that? It all depends on the level of the height drop at extreme points, the planned minimum thickness of the screed, the area of \u200b\u200bthe room, the characteristics of the solution.
Usually, the packaging of dry construction mixtures indicates the normalized consumption in kilograms per square meter of the pliable area with a layer thickness of 10 mm. Based on this, it is possible by easy calculations to determine the required amount of material.
To facilitate the readers of the task - a calculator that allows you to quickly and accurately produce such calculations.
A traditional approach to the repair of the floor in the panel house is "wet" screed from cement-sandy solution. This is a time-consuming method that takes a lot of time on a set of solutions of the solution - 28 days. A lot of components, noisy preparation of a graded solution in the apartment and the hygroscopicity of the finished layer make the process inconvenient, and the result is far from perfect.
Alternative to the solution - dry screed according to Knauf technology. It eliminated side effects of floor alignment in the panel house.
- Harness - no "wet" cycles.
- Noise - only the screwdriver and jigsion are involved.
- The complexity of the solution is a screed of two components - clay filling and sheets on a plaster basis.
- Tightened deadlines - the replacement of sex on the "dry" technology in the same room takes one day.
- An uneven surface is a Knauf gypsum fiber leaf with an ideal factory plane.
The screed on the ceramiz does not require drying and removing evaporated moisture, and its components meet the requirements of GOST 4.230-83 "Finishing materials".

Simple floor replacement technology in the panel house
The system that the company "Right floor" offers is focused on the 5 main requirements of residents and those who use the premises.
- Smooth surface that is suitable for laying linoleum, carpet, laminate, parquet board or ceramic tiles.
- Soundproofing for your own comfort and calm neighbors from below.
- Fast neat installation without spots, noise and dirt for 1-2 business days.
- Non-toxic materials, safe for health throughout the life.
- The final cost is lower than the proposals on the market.
After dismantling the old coating and marking of the laser level of the wizard, the complexity is found: the number and size of level drops. Depending on the drops of the base level of the floor - concrete slabs - the KNAUF system can be executed in four versions:
- Alpha. The sheets of GVV are immediately fit at the alignment.
- Beta. The screed is performed by Polynemplax and Knauf Hypus Fiber List on aligned grounds.
- Vega. Dry flowing screed with clay type "Compavit" fraction 1-5 mm thick up to 100 mm. After this height, the firming sheet of GVLV is applied.
- Gamma. Dry fridge, an additional GVLV leaf 10 mm - heat and soundproofing-elements of the floor Knauf.
In all cases, the perimeter is satisfied with a damper tape from foamed polyethylene, paro insulation for moisture protection is placed on the base.
How we make a floor screed in a panel house
There is also an analogue of Knauf sheets, it is the GSP sheets. They are easily and accurately processed without dust, 25 kg weigh per 1 square meter. m, have good adhesion to tiled adhesives and perfectly smooth factory surface. The plates are made with a lock on the edge, they are bonded among themselves into a solid seamless plane with glue and conventional self-draws.
How to calculate the price of floors
The usual estimate on the cement-sand tie can be painted on several sheets. The main components at first glance inexpensive, however, the cost of work can be up to 80% of the consumable part depending on the complexity of the work and the appetites of the master.
In our company, all processes are transparent, so we propose to calculate the cost of a dry screed on the specified quadrature using the calculator. For example, for a room of 12 square meters. M Crawling 50 mm thick performed by Economy will cost 15,400 rubles, of which 8,200 rubles were laid on the material (53%), and 7,200 rubles (47%) were paid to the work. The company "Rivinal floor" also offers related services: delivery, dismantling and laying of the floor covering.
