Waterproofing the foundation with its own hands: how to make the waterproofing of the foundation at home. Waterproofing ribbon do-it-yourself coating technology with roll materials

Ribbon foundation is often used to ensure the stability of buildings on dry and bunched soils. It represents a concrete strip, sprinkled around the perimeter of the future structure. Since the material from which such a base is manufactured can quickly collapse under the action of water, the waterproofing of the belt foundation is a primary task for the builder. There are several types and methods for performing this work that it is worth considering.

What you need to consider before choosing the type of foundation waterproofing

If in the process of designing a home the choice fell on the filling of the tape basement, the masters should hold a number of studies to perform their work correctly:

the foundation itself must be lower than the level of the freezing of the Earth;
it is important to take into account the level of groundwater;
requirements for waterproofing may vary depending on the appointment of the future structure;
it is necessary to explore the terrain on the subject of a sharp rise in water after floods and severe precipitation;
an important factor will be the strength of the soil, affecting the changes in the level of soil.

All these factors can affect the depth of the trench, which they will have to dig up under the foundation, and used water protection products. By type of location of the waterproofing of the foundation from the FBS blocks, it is divided into horizontal and vertical, which have several embodiments.

Horizontal waterproofing

This type of hydraulic protection is performed before the start of the foundation in order to prevent capillary water from the bottom. To fulfill the tasks set, it must be a special base, possibly more than the perimeter of the future at home. For a small structure there will be enough screed from cement and sand in proportions 1: 2.

During the construction of a residential building, more serious preparation will be required:

the bottom of the pit is stacked and the sand layer 20-30 cm is stacked;
to start work instead of sand, you can use clay;
top of the first layer is applied cement screed with a thickness of 6-8 cm;
then you need to wait until cement dry, which takes up to 14 days;
then the first screed is covered with bitumen mastic and placed rubberoid;
on top of the rubberoid layer is closed by another layer of mastic;
the second screed is done.

After complete drying of the material begins the manufacture of the foundation.

If the estimated structure is from wood, it is worth performing and the upper horizontal waterproofing of the belt foundation. Otherwise, the water will come to the wood, causing her rotting.

How can the top layer of horizontal waterproof be performed and it is easier to cut the ruleroid roll, you can see in the next video:

Vertical hydraulic protection

Unlike horizontal waterproofing, this type of work can be performed not only in the construction process, but also when protecting the finished structure from moisture exposure. At the disposal of masters there are several options for materials used for waterproofing of the FBS blocks:

polyurethane mastic;
bitumen in rolls;
polymer membranes.

All these tools are distinguished by strength, durability, elasticity, installation methods and cost, so before choosing one of the proposed methods, the master should be determined by the difference between waterproofing materials, their strengths and weaknesses.

Bitumen isolation

This method is considered the most common than due to the low value of the material, its elasticity and simplicity in applying. Liquid mastic fills all the formed gaps and emptiness in the foundation, preventing moisture penetration inside. Such waterproofing of the ribbon foundation can be performed by the efforts of one person.

Bitumen mastic compositions differ in heat resistance, so when choosing it is worth paying attention to the marking. Its last two digits indicate the maximum permissible temperature at which the composition retains its properties.

However, the method has its drawbacks. The composition is applied in several layers, which increases the duration of work. It does not guarantee protection for all 100% and requires re-processing the foundation after 10 years.

Before applying a layer of mastic requires surface preparation. It must be solid, with rounded corners, without sharp protrusions, with the most smooth transitions from the horizontal to the vertical. If there are traces from air bubbles in the foundation, they should be lined with fine-cellular cement mortar. Also, the surface must be cleaned of dust and dirt. All this will affect the evenness and integrity of the applied composition.

Be sure to check the surface to humidity. If the indicator is more than 4%, the bitumen does not fall a strong layer, but will begin to settle down a short time after applying.

The next stage of work is primer. It is performed either a bitumen primer, or a mixture of BN70 / 30 bitumen with gasoline in a 1: 3 ratio.

To apply the mixture, it will take a roller or brush. In places where the base has joints or irregularities, it is necessary to apply 2 layers of primer. After that, you can proceed to the coating of the foundation of the mastic.

For its preparation, large pieces of bitumen are crushed and melted in a bucket. Since the composition already during the first heating partially loses its properties, it is worth using the mixture before it cools.

To ensure more reliable insulation, it is worth a 3-4 layer. To protect the mastic from above is covered with geotextiles or thermal insulation layer. At problem areas, mastic is required to rein the glass cholester or fiberglass.

Rolled waterproofing

This type of hydrochrolation FBS can be used as an addition to mastic, and as an independent way to protect the foundation from moisture. The material is most often used runner, which is characterized by low cost and availability. Compared to mastic, it protects the base from moisture much longer (up to 50 years). At the same time, it will be impossible to fulfill this work one.

To cover the foundation or socket runner, you first need to prepare the surface and cover it with bitumen mastic. In this case, it is not necessary to take care of the care of the layer, since it will perform the function of fastening the runner to the surface.

The sheets of the main coating must first be heated below with a burner, and then put them on the bitumen layer. Ruberoid is put on 10-15 cm. For additional fixation, all joints are also heated. After attaching the foundation simply falls asleep without additional protection.

Instead of runner, you can apply more modern materials, such as polymer films with bitumen-polymer spraying. The principle of work will remain the same. The difference will be on the service life of the coating and price.

Other waterproof methods

In modern construction practice, along with the methods described above, there are a number of alternative methods:

As a waterproofing, an ordinary layer of plaster can be used. The service life of such a coating will not be long due to the low hydraulic resistance of the material (no more than 15 years), but it is not difficult to apply again.
To protect against fluid, the ribbon foundation can be coated with a composition based on liquid rubber. The quality of waterproofing in this case will be high. The minuses of this solution will be the high cost of materials, including a special primer composition, the presence of a sprayer or low speed due to its absence.
Penetrating hydraulic protection based on special compositions can be used both for external and for internal processing of buildings. The difficulty for the master in this case will be a small prevalence and the high cost of such a method.
Masters can be asked to create a clay castle. For this, the trench is digging around the perimeter around the foundation, the bottom of which is covered with a mixture of sand and rubble, and on top of the remaining space are closed with a layer of clay, which becomes a reliable barrier for groundwater or abundant precipitation.

Waterproofing foundation is an important part of the design and construction of any building. This is the main protection of any wall design. Depending on the type of hydraulic protection, it can be carried out or before the manufacture of the foundation, or after the construction is completed. The complexity of manufacturing, the cost and service life depend on the selected material and the correctness of its application.

Device drainage system

The foundation is the main part of the house. The durability of the building as a whole depends on its quality. For the base of the house, soil, rain and capillary waters are affected, which is why it can be asked and deformed. Concrete - hygroscopic material. The moisture, which he absorbs, rises to the capillars, penetrating the walls and floor and causing the formation of mold and fungus. When freezing this water, the foundation may be destroyed. In order to protect the house from destruction as a result of moisture impact, a timely waterproofing device of the foundation is necessary. If you still think, whether to do waterproofing, keep in mind that the repair of the foundation will be more expensive in the future than the construction of the house, and the difficulty and complexity of the work and it is not worth it.

Foundation waterproofing scheme.

It cannot be said that the implementation of such works is an easy task. Waterproofing technology requires certain skills and understanding the processes that occur in concrete and soil and in various materials. Experience has been important, therefore, before performing work, it is necessary to consult a specialist and follow its recommendations.

Waterproofing technology at home

First you need to decide on the complex of construction work on waterproofing. At the same time, it is necessary to take into account the following factors: the level of groundwater occurrence, frosty powder, conditions of operation of the house, the inhomogeneity of the soil. If the maximum groundwater level is below the basement of the foundation per 1 m or more, it suffices to produce vertical coating waterproofing and horizontal using rubberoid.

The main types of waterproofing foundations.

If the soil waters lie closely from the foundation, but the basement level does not reach, the work complex will have to expand. Horizontal insulation is performed in 2 layers, each of which must be missed by bitumen mastic. For vertical waterproofing, both the occupus and coating method are used. Depending on the budget scheduled for the purchase of building materials, all concrete structures can be treated with penetrating materials that stop the movement of water in capillaries.

If the groundwater is laid above the basement soles and basement floor, you must additionally equip the drainage system. The price of waterproofing the foundation depends on its area, the number and type of materials used. In the simplest case, you will have only bitumen. In the most difficult one, you will have to spend on penetrating, rolled and coating materials, as well as on the arrangement of the drainage system.

Horizontal waterproofing foundation

For a monolithic and tape base, horizontal waterproofing is carried out in 2 places: at the floor level of the basement and in places of the foundation with walls.

Horizontal waterproofing can be performed only at the building of the building, so it is necessary to take care of it on time.

To do this, you will need the following materials and tools:

Scheme of horizontal waterproofing.

shovel;
grease clay;
concrete;
bitumen mastic;
ruberoid;
cement;
rollers, brushes;
adhesive mastic.

Before the construction of the foundation on the bottom of the bottom, it is necessary to float a layer of oily clay with a thickness of 20-30 cm, which you need to carefully tumble. After that, poured a layer of concrete at 5-7 cm. This is necessary for the arrangement of the foundation waterproofing. Before laying the material, the concrete must dry and dial the required strength. Then the concrete is deceived by bitumen mastic, on top of which the rubberoid is placed.

The surface is again covered with mastic and put the second layer of rubberoid. Top poured concrete and perform an iron. It is also included in the complex of work on the insulation of the base. It is done so: on top of the concrete fall asleep sieve through sieve cement and smash it. Cement is worst from the moisture contained in the concrete. Then the surface is periodically wetted by water until it gains strength.

After the ribbon or pile foundation is built, its surface should also be hydroizing to prevent moisture raising into the walls. The surface is covered with bitumen mastic, on top of which rubberoid or any other rolled material. The procedure is performed twice to obtain two-layer waterproofing. The edges of the material are not cut, and they are cut down and pressed with vertical insulation.

Device drainage system

An option with a waterproofing device and a fundamental wall drainage.

Depending on the depth of groundwater and soil type, it may be necessary to arrange a drainage system that serves to collect and remove atmospheric and groundwater into the well. Such a need mainly occurs with poor penetability of soil and high groundwater. To build a drainage system, you need to dig a trench around the perimeter of the building at a distance of about 70 cm from it. Depth depends on the level of groundwater. Width - 40 cm. The trench should be located with some slope relative to the pit and the well.

The geotextile is placed onto the bottom, the edges are wrapped on the side of the pits by 90 cm. The crushed stone or gravel with a layer of 5 cm along the length of the trench and the perforated pipes are stacked with a slope of 0.5 cm for each m. Then the pre-washed gravel is covered with the remaining edges. geotextile. Pipes are displayed in the collecting well, and the backflow of the soil is produced. The drainage system can be equipped after commissioning.

Vertical waterproofing of the base of the house

Scheme of vertical waterproofing foundation.

To do this, you can use a variety of materials that can be combined. The cheapest is considered bituminous waterproofing of the foundation. This will require bitumen sold in bars. 70% of the bitumen resin and 30% of spent oil are laid into a large capacity. Chanic need to warm up, explore the fire under it. After the bitumen is melted, it can be applied to a pre-aligned surface. The brush or roller bitumen is applied to the surface of the base, starting with its sole and ending 15-20 cm to the surface of the soil. Bitume need to be applied in several layers, bringing the total thickness to 3-5 cm. To the bitumen does not frozen in the container, it must be hot all the time.

Bitumen fills the pores in concrete, protecting it from the penetration of moisture. The service life of such waterproofing is 5 years, after which the coating begins to crack and collapse, passing water into concrete. To extend the service life of waterproofing, bitumen-polymer compositions are used that do not have deficiencies in the usual bitumen.

Powered waterproofing foundation

Scheme of waterproofing foundation Ruberoid.

Rolled materials can be used separately or in combination with coating. The most popular stroke material is the rubberoid. Before fixing it on the surface of the base, it is treated with bitumen mastic. After that, the rubberoid canvas are heated by the gas burner and are applied to the surface with the overlap 20 cm. Ruberoid can be attached using adhesive mastic. Before moving the vertical waterproofing of the edge of the edge horizontal, you need to wrap and press, moving on top of the runneroid.

Ruberoid can be replaced by more modern polyester-based materials that increase their strength, wear resistance and elasticity. But they cannot provide the necessary coating strength without prior applying mastic, as they do not fill the pores.

Scheme of waterproofing the foundation of liquid rubber.

Having waterproofing can be replaced with liquid rubber having a good clutch with the surface. The surface will be seamless, which will provide high-quality protection. If work is performed manually, the Elastomix or Elastopasis is suitable - single-component rubber. "Elastopaz" is applied in 2 layers, each of which should be dried at least 24 hours. Sold in the containers of 18 kg, if the content is not completely spent, the bucket can be sealed and leave material for storage. Elastomix is \u200b\u200bapplied by one layer, it is sold for 10 kg. If the bucket with a mixture is not spent to the end, it cannot be stored, since after 2 hours it will turn into rubber.

The surface covered with liquid rubber requires protection against external influences if the soil of the backfill has an inclusion in the form of stones or construction waste. The foundation in this case is covered with geotextiles and equip the clamping wall.

Penetrating waterproofing foundation

Scheme of penetrating waterproofing foundation.

Penetrating materials are called materials whose substances penetrate into the structure of concrete and crystallized inside. The hydrophobic crystals protect the concrete from the penetration of water into its structure and its raising by capillars. This prevents the destruction of concrete and increases its frost resistance. Such materials such as "Hydrotect" and "Aquatron" are penetrating waterproofing, most often they are treated with the inner surface of the basement or basement. Apply penetrating materials better on wet concrete. To do this, the surface must be cleaned from dust and carefully moistened. The material is applied in several layers. After it is absorbed, the outer layer can be deleted.

For waterproofing and aligning the vertical surfaces of the foundation, plaster mixes with moisture-resistant components can be used. Plastering the foundation just like walls for lighthouses. To prevent the appearance of cracks, the plaster must be applied with a hot way. The plaster layer after drying should be protected by a clay lock.

The clay castle does not allow pressure water to the foundation. To do this, around the perimeter of the foundation at a distance of 0.6 m, a trench is digging, on the bottom of which crushed stone. The walls and bottom of the trench are covered with fatty clay. The remaining space can be covered with clay or gravel, and to make a break from above. During the spring flood, the clay does not pass water to the base, and the extra moisture goes through the gravel layer.

Foundation Waterproofing Device: Work Technology

The foundation waterproofing device starts with horizontal insulation. It is possible to perform it using bitumen, rubberoid, liquid rubber, etc. Materials. They are used for vertical isolation.

The ribbon foundation of your home should be "dressed" into waterproofing materials. The correct and reliable waterproofing of the belt foundation of your home is one of the priorities you need to solve.

The ribbon is a reinforced concrete strip. It goes through all the external sizes of the structure and the carrying inland walls.

From life experience, we know that in order to keep our health with you, we wear warm things in cold weather, we are worked out, respectively, in crude weather. Fishing and hunting in special marsh boots, so as not to soak our legs and not get sick. But many mountain builders think that the built house, in particular, its foundation, can be in a fairly raw and cold medium - in the ground - without protection against this aggressive environment.

Therefore in order to build the house:

pleased you and not one generation of your descendants;
was a "long-lived" for which it is necessary to preserve the "health" of your home;
did not give trouble from frequent repairs, alterations, reconstructions due to illiterate construction and subsequent operation,

be sure to need a modern technology for isolation from groundwater.

With this important issue, we must figure out.

Ribbon foundations (scheme).

To create waterproofing, which will serve you for many years, it is necessary to apply high-quality, especially for this purpose with certain properties and characteristics.

The material used should be:

Modern materials have these properties and differ only to a greater or lesser degree of their manifestation.

Good drainage

Light soils - sand and sandy - are able to easily skip the appearing moisture into lower soil layers. Water does not stir up near the foundation erected, and therefore waterproofing may be slightly lightweight compared to the waterproofing device on heavy, bubbly soils - clay, loam.

As a rule, on bubbly soils, a drainage system for collecting and removing moisture from a concrete foundation is arranged. For this, special drainage membranes are used, which are placed under a monolithic plate on which a ribbon foundation is standing.

Drainage system circuit.

Under the sole of reinforced concrete tape of the foundation performed in the trench (without basement) on all external and internal carrier walls of the house, with a depth of the base of the foundation by 20-30 cm below the ground freezing point, be sure to build a sand-gravel or sand-gravel pillow. Such drainage is able to take moisture to lower layers of the Earth. The width of the bulk and the rammed pillow must be greater than the width of the ribbon foundation by 20 cm. The pillow prevents stagnation of water and tightening or clay when lifting the level of groundwater surface of the foundation and damage to vertical waterproofing. A vertically installed drainage membrane helps to remove excess water from the building, does not allow it to put pressure on the waterproofing itself and to look for weak points in it.

Horizontal and vertical insulation

Scheme of the device of horizontal waterproofing

Horizontal waterproofing is performed under the monolithic slab by laying the drainage membrane to the monolithic layer of skinny concrete with a slope into the removal pipeline, followed by mounting the reinforced mesh and the fill of the monolithic foundation plate on which the ribbon foundation is assembled or poured around the perimeter of the house.

Horizontal waterproofing is also made to separate the top plane of the belt foundation and the starting wall. It is performed by spraying the appropriate material or the oscillating of rolled waterproofing materials.

All vertical planes of the belt foundation from the top to the niza are closed by modern materials specially designed for this.

Several types of waterproofing

Non-free waterproofing protects the ribbon foundation from external precipitation penetrating into the soil, and from the spring and autumn temporary lift of the groundwater level.

For reliable anti-phonic waterproofing, the basement is better to apply three layers of sludge.

After performing vertical waterproofing, fill the foundation. The best result is achieved with layer-by-layer inertia, well-conductive water materials, such as quartz (river) sand with the smallest clay impurities, gravel weight or earth. The frustration of the construction garbage is undesirable, since it is after this operation that damage the integrity of the waterproofing of a tape basement. On the surface of the Earth around the perimeter, the building makes a breakdown of 1 m wide from concrete or asphalt.

Anti-profic insulation, in turn, protects the base of the house from contact with constant close-range groundwater in the zone of finding the foundation. For such purposes, reducing, sprayed, paint materials are used. After applying such insulation materials, a solid layer of insulation without joints and seams with good repulsive properties is formed.

Capillary waterproofing prevents moisture droplets from entering into concrete monolith. The best results it gives with the impregnation of concrete with compositions both with the inner and the outside of the foundation tape. The impregnating compositions penetrate the depth of concrete for several centimeters, filling the smallest pores in concrete, making the ribbon foundation almost hermetic and able to confront the external moisture.

The diagram of the adjoining horizontal and vertical waterproofing.

Sequence of work

Works on the isolation of the ribbon foundation from the external impact of the medium should pass on the surface purified from dirt.

First of all, it is necessary to choose a method of application, and at the same time the insulating material itself.

Refractory waterproofing is performed by mastic, bituminous compositions, liquid glass. In most cases, it is used as the first layer of insulation and as a binding layer for gluing rolled materials.

After this layer, the foundation is covered with rubberoid or other rolled materials by two layers, sticking the layers on mastic. The junctions are performed with an overlap 20 cm.

Waterproofing is possible and using spraying with special compositions with a sprayer.

After performing any type of waterproofing, it is advisable to mount a special rolled profiled membrane that protects waterproofing from damage and contributes to the allocation of excess water from the foundation. The membrane is also rolled up with the allen on the joints at 15-20 cm.

Waterproofing of the ribbon foundation with their own hands includes the protection of vertical parts and the horizontal surface at the level of the base. Side parts are missing by bitumen if there is contact with the soil.

This type of foundation is perhaps the most dispersed construction supporting structure for residential buildings, because construction work on its construction is quite simple. Waterproofing of the ribbon foundation with their own hands includes the protection of vertical parts and the horizontal surface at the level of the base. Side parts are missing by bitumen if there is contact with the soil.

It is worth the cancellation that the consumption of materials for waterproofing work on the belt foundation is quite moderate, which makes such a supporting construction structure optimal in terms of price, quality and timing of construction.

One of the main criteria for the calculations of the belt foundation is the composition of the base of the base and the level of groundwater occurrence. In addition to the calculations of the sizes, the scheme of the reinforcement of the frame and the brand of concrete, these parameters are also important to take into account when the waterproofing device of the finished design, as it will largely determine its durability and carrying ability.

Features of insulation works on a tape foundation

Horizontal waterproofing device diagram

Those who first face the construction of their homes and decided to build it on a belt small-breeding foundation, one should remember an important point - the waterproofing of the ribbon foundation is carried out necessarily! This rule can not be neglected even in cases where the structure will be located on the rocks of the ground of the groundwater level in the freezing zone. In addition to the waterproofing and insulation of the foundation itself, it is extremely desirable to make a break.

Waterproofing of the belt foundation consists of the following steps:

Insulating work carried out at the stage of earthworks. These works include a horizontal layer of the runneroid under the foundation pillow. This protection is placed directly to the ground, a drainage layer or coarse-grained subftitude, depending on the design structure. The main task of this layer of runneroid is to protect the foundation pillow from possible flooding or frosty soil. To prevent premature destruction of such a design with atmospheric precipitates, it should be protected by a breakfast. The cushion under the foundation may not necessarily, the need for its presence is established by calculations or project work.
Horizontal waterproofing. This type of protection is applied to the concrete pillow, in front of the device of the belt monolith. It is necessary to protect the junction between the two elements of the design - the foundation pillow and the most belt foundation. If you do not perform horizontal insulation, then water that fell into such a joint, after freezing it can violate both the integrity of the entire design and damage the individual elements of the foundation. In addition to the protection device, between the ribbon and the pillow, the lighting of the rubberoid between the top surface of the foundation and the material of the walls of the walls (for example, brick masonry) also relates to horizontal waterproofing. The functional purpose of such protection is similar to the one that is arranged between the pillow, the sole and the belt supporting structure.
Vertical waterproofing. Such protection of the design from moisture should be performed both on the outer surface and on the inner. This is the most important part of the insulation, it is its device to ensure the durability of the whole design. It is possible to perform horizontal insulation as a rolled material, for example, rubberoid and liquid binding on a bitumen basis, such as bituminous mastic. In addition to such isolation, the foundation should necessarily be a breakfast, only the combination of these two elements will be able to effectively resist moisture.

The need for protection

Schematic mapping of vertical and horizontal waterproofing with a sandy pillow (sole) on Earth

For those who want to save on separate stages or completely abandon the protection of the foundation from moisture, it should be remembered that even after insulation and decorative finishing of the horizontal part of the tape structure, the concrete will still continue to absorb moisture entering through the air.

This moisture will gradually destroy the concrete, as the microorganisms and disputes and disputes will penetrate with it, and the moisture itself may contain solutions of aggressive components, which will also affect the design, which first can lead to microtrees, and then to the surfaces of the surface .

To further protect the entire design of precipitation and flooding waters, you also need a scene - without it, the base is blurred under the pillow (sole), which will create an additional load on the carrying elements of the whole building. Also, the scene will not penetrate moisture in the ground in the formation of areas of standing water near the house, and after this water is removed, the scene will protect the ground from rapid drying and the formation of cracks. It should be erected under the bias from the building to ensure water drain. The shake of the scene and the foundation also need to isolate.

Procedure for work in the device of rolled waterproofing

The use of rolled material for vertical protection of the carrier design

Before starting work, clean the concrete surface from dirt and dust, as well as eliminate the protruding sharp elements so that they do not damage the material. Then it should be placed and cut the runneroid.

To glue the material, it should be heated with a gas burner so that the knitting material becomes liquid on the glued surface, after which it is possible to glue.

During the application of the material, it should be immediately smoothed in order to properly accepted the design form and filled all empties, also this procedure will remove air bubbles. If one piece does not work on some kind of plot, then the dock should be made to produce a mustache, warming up the edge on both sheets and tightly pressed them, only then they smear.

Insulation should be applied to a clean concrete surface, it is not recommended to handle it before this binding on a bitumen basis, unless this is the materials from one manufacturer, which provide for sharing. Otherwise, the rolled material may not stick, due to the difference in the chemical composition of the organic binder component.

Procedure for work in the device of coating waterproofing

Treatment of the base of the base with mastic standing on the pile foundation (pile-tape)

For these purposes, an organic binder is used on a bitumen basis, most often bituminous mastic. Before applying to the surface it needs to be made of liquid, for which a special solvent or heating is used. Before starting work, you should carefully read the manufacturer's instructions, which also give recommendations for the discharge. When the composition is ready, it is applied with a brush or roller in several layers, filling all the pores and emptiness.

It should be noted that compared to rolled insulation, the cooler is less durable, and it should be used only in the absence of a threat of flooding and low groundwater levels. Before the device, the device should be applied an additional layer of coating, the scene itself can also be covered with mastic, but only after the complete drying of the concrete mixture.

Example of construction and waterproofing of the collection belt construction

We present a specific example of waterproofing the belt supporting design without protection of the soles bitumen:

The house is designed without basement and basement. For about 145 meters water. Soil clay-merry. A trench of a depth of 100 cm is reaping. The layer of granite rubble without sand (150-200 mm). The reinforced tape of four rods with a diameter of 12 mm is laid.
