How to properly reclaim a site with clay. How to make drainage ⛲ in the area around the house on clay soils with your own hands

If the soil around the house consists of loam and clay, then in the spring and after rains, the territory of the estate turns into a small swamp. It is necessary to drain it somehow and quickly, otherwise the plants will rot, and the foundation will begin to fall apart. Let's figure out how to drain a site on clay soil in order to quickly remove excess water from it.

Excess moisture in the soil leads to oxygen starvation of plants. The roots do not receive the required amount of oxygen, which inevitably leads to the death of the greenery. This problem affects trees, shrubs and lawn grass... Without effective drainage, not a single plant will survive in a clay area, water will destroy everything.

Herringbone drainage system - the best option for a small area

A land with excess moisture is an ideal incubator for all kinds of slugs and snails. And which gardener needs these pests that feed on garden plantings? Plus, waterlogged soil is a direct threat to the foundation of the house. No waterproofing layer will save the base of a building when exposed to constant water.

Clay itself does not allow moisture to pass through, and if the site is also in the lowland, then drainage system will have to be done without fail. Otherwise, not only the future harvest, but also the owner of the house runs the risk of drowning in the mud.

How to determine clay soil or not

It is possible to accurately assess the characteristics of the soil only after appropriate surveys, which should be carried out by a professional hydrogeologist. A variant is possible when the clay does not protrude to the surface, but lies in a continuous layer at a shallow depth. There seems to be good soil from above, but literally half a meter later, a clay layer begins, which does not want to drain moisture further into the depths.

Only the degree of permeability of the earth can be roughly determined. To do this, it is enough to dig a hole half a meter deep and pour water into it. If after a couple of days the deepening turns out to be dry, then the site can do without additional drainage. Otherwise, you will definitely have to do drainage on it.

Drain the clay area with your own hands

There are two main ways how you can drain the clay area:

  1. With the help of a surface drainage system from trays.
  2. By means of deep drainage with the installation of perforated drain pipes.

The first option will allow you to take away only thawed and rainwater... Only a buried system can handle moisture already in the soil.

Drainage scheme for a site with clay soil

Wells, trays and pipes can be made of concrete, asbestos cement, or iron. But the most practical material- plastic. From cross-linked polyethylene, you can now purchase a whole set of various elements of the storm sewer system, you just have to put them together.

Advice! Pipes, storm water inlets, wells and storm gutters are best bought from cross-linked polyethylene. It easily tolerates frosts and does not crack when freezing.

The choice of the type of drainage depends on:

  • the owner's capabilities in terms of finance;
  • area and relief of the land plot;
  • estimated amounts of precipitation;
  • soil structure at different depths.

In any case, first it is necessary to prepare a draft plan of the drainage system with reference to the terrain and purchase all the necessary building materials.

What is needed to build a water drainage system

To drain an area with clay soil from tools, you will need:

  1. Shovels for digging pits for wells and trenches for drains.
  2. Garden wheelbarrow.
  3. A hacksaw for metal or a jigsaw for cutting pipes.
  4. Twine cord for marking.
  5. Construction Bubble Level

And also you should stock up in advance:

  • fine gravel with sand;
  • pipes with a diameter of 110 mm with perforation (you can take ordinary sewer pipes and drill holes in them);
  • geotextile material for wrapping perforated pipelines;
  • pipe fittings;
  • gutters, sand traps and storm water inlets (plastic or concrete);
  • factory-assembled well structures.

Installation of surface drainage

Open drainage on clay soil is the easiest to do. If the groundwater is deep enough, then it will be enough to drain the adjacent territory. In terms of labor costs and finances, this option is optimal.

Scheme of surface stormwater from individual elements

The system of collecting and draining water trays for surface drainage is laid with a slope from the house to the lowest point of the site where a septic tank or infiltrator is equipped. From the septic tank, the clarified liquid is discharged into a roadside ditch, a nearby pond or street storm drain.

The main thing when planning a drainage system is to make the most of the relief of the site. If it has a bias, then this is just the perfect case. It will be enough to dig ditches along this slope and lay trays in them at an angle to the lowest point.

Open drainage can be made in the form of comfortable stone gutters

Installation of surface drainage in a clayey area is carried out in five stages:

  1. Digging trenches according to the projected scheme with a depth of up to half a meter.
  2. Filling at the bottom of the ditches with a 15–20 cm thick sand and gravel cushion.
  3. Laying trays at a slope of 2–5 degrees to the water intake.
  4. Covering storm gutters from leaves and debris with metal grates.
  5. Installation of an infiltrator with drainage into the soil below the clay layer or a storage tank with a pump.

After completing all the work, it remains only to check the performance of the storm drain by letting water into it from the hose.

Deep drainage device

A buried drainage system is formed from a main pipeline and perforated pipes connected to it. The line can be made alone - in the middle of the site, then the drains are connected to it with a herringbone pattern. Or it is laid along the fence along the border of the estate, and all drainage pipes are connected to this perimeter.

For laying pipelines, trenches 35-40 cm wide and up to one and a half meters deep are needed (depending on the level groundwater and points of soil freezing). At their bottom, a 15-centimeter cushion of sand with rubble is made and geotextiles are spread, which protects the perforation from clogging.

Then another 10–20 cm of gravel is poured onto the geotextile substrate and drains are laid on it, which are then sprinkled with gravel and covered with geotextile on top. As a result, the perforated drainage pipe should be in gravel on all sides and wrapped in a circular geotextile.

Distance and depth of placement of drains in various soils

Important! Perforated pipes without geotextile wrapping on earth with clay will quickly clog. Needle punching geotextile - required element deep drainage in a clay area.

When arranging drainage in areas with clay buds, in addition to the usual non-woven fabric, you can use voluminous coconut fiber casings to wrap pipes. Drains with them are sold ready for installation.

Layout scheme for drainage perforated pipes

Revision and storage wells can be made from:

  • bricks;
  • reinforced concrete;
  • plastic.

If the pipes for the drainage system are plastic, then all wells and a septic tank are also better used from a similar material. It's easier to take care of them later and make repairs if necessary.

The combination of a deep and surface drainage system is guaranteed to drain even a swampy area. Such drainage of clay soils has been proven over the years of practice. Its installation is simple, and as part of the service, seasonal inspections and flushes are sufficient. But it is better to entrust the design of the drainage system to an experienced specialist. There are many nuances and without specialized knowledge it is difficult to correctly calculate the depth of the laying, slope, diameter of pipes.

A constant problem of some owners of private houses is the flooding of the adjacent land plot with groundwater. This complication is caused by the special composition of the soil. If a large proportion of the soil is clay, then the earth tends to erode. To avoid the described problem, a drainage system is required on clay soil.

Drainage in soil, which mainly consists of clay, can be surface, deep or stratal. Although in some cases, in order to increase the efficiency of drainage on eroded soil, it makes sense to organize a combined system.

The creation of surface drainage is resorted to when the territory of the site has a pronounced slope to one side. As a result, the water runs off on its own along the channels made in the ground and goes into a certain zone. Ways to drain excess moisture are organized in top layer land.

It is customary to lay a surface drainage system in places without irregularities: near paths, next to the walls of a building, along the perimeter of green lawns and near recreation areas. Drainage elements in these areas should be plastic or concrete gutters that carry water to drainage wells... The function of the last links of the system is to accumulate or dispose of excess moisture.

Surface drainage grooves shallow

Deep drainage is a network of canals and pipes embedded in them, located at a depth of 1 meter and directing water to the wells. The width of the trenches for draining excess water is about 50 cm.

The trench for deep drainage is covered with waterproofing material, and a layer of gravel is poured on the bottom

Between the channels in the soil with a high content of sedimentary rock, it is supposed to leave no more than 11 meters of free space. The exact distance from each other to lay drainage pipes depends on the type of soil and the depth of the dug trenches.

Table: distance between drains depending on their depth

Drain depth, m Distance between drains, m
Light soils Medium soils Heavy clayey soils
1,8 18–22 15–18 7–11
1,5 15,5–18 12–15 6,5–9
1,2 12–15 10–12 4,5–7
0,9 9–11 7–9 4–5,5
0,6 6,5–7,5 5–6,5 3–4
0,45 4,5–5,5 4–5 2–3

The reservoir network of drainage channels is considered a subspecies of a deep drainage system, since it is organized at great depths. The need to create reservoir drainage arises when the foundation of a building is flooded, which stands on a damp clay area.

The channels of the reservoir drainage system are laid directly under the foundation, deeper than its lowest point. The system includes a crushed stone embankment, the task of which is to direct water into pipes placed around the perimeter.

Reservoir drainage pipes are placed in a ditch under the foundation below the depth of its laying.

Installation of a drainage network in clay soil

Only thanks to the construction of a drainage system will it be possible to dry the clay soil and make it fertile in almost a year. Is that land plot really needs a drainage network, you can verify with a test. It consists in digging a hole 50–60 cm deep in the ground and filling it with water. Poor soil permeability, that is, the presence of any amount of water in the created depression for a long time, serves as a signal of the need for arrangement at the site of the drainage system.

If there is water in the dug hole long time and does not go away, so you need to make a drainage system

When creating drainage in an area with a high clay content, attention is paid to such aspects as:

  • the cost of organizing a network of drainage canals;
  • the area of ​​the flooded zone;
  • the degree of soil moisture by precipitation, melt and groundwater.

Having considered these conditions for arranging drainage, they decide which method of channeling to choose - superficial (cheaper) or buried (difficult and expensive). The owners of land plots, who have guessed to combine both options of the drainage system, act most correctly. This approach to soil drainage allows for better results.

The drainage system is created using geotextile fabric and perforated ceramic, asbestos-cement or PVC pipes. The grooves for removing excess moisture from the soil are first loosened and filled with sand. After that, pipes are laid in them, covered with crushed stone, and then covered with geotextile and another layer of sand. Earth is laid on top of the entire system.

The protective layer of gravel is wrapped with geotextile to protect it from siltation

Drainage scheme on clay soil

A self-constructed drainage system is a network of interconnecting lines laid in an area where excessive soil moisture is observed. Excess water from the soil can flow out through pipes with an inner diameter of 100 to 988 mm. Products that remove excess moisture are wrapped in filtering cloth and covered with rubble so that debris does not get into them.

At the points where the pipes connect or go in the other direction, inspection wells are mounted, which make it easier to clean the system and provide an opportunity to monitor its operation. The collected water is transferred to a special well at a distance of 40 meters from the site, a ravine or a reservoir. Sometimes pipes that draw excess moisture from clay soil are led into a concrete ring, which is covered with a lid to prevent debris from entering it.

Instructions for creating water drainage channels

Before starting work on the organization of the drainage system, you need to stock up on the following inventory:

  • bayonet and shovel;
  • garden cart (to bring materials and take out waste soil);
  • hacksaw (for cutting pipes).

Of the materials you will need:

  • geotextile matter;
  • perforated polymer pipes;
  • crushed stone;
  • sand.

To lay a network of canals in clay soil, take the following steps:

  1. A drawing of the drainage system is made on paper.

    The drawing shows a diagram of the laying of drains and the location of wells, inspection hatches and other elements of the system

  2. Land plot is marked out. Drainage pipes must not be laid closer than 50 cm from the fencing of the territory and 1 m from the foundation.
  3. Ditches 1 meter deep are dug in the soil under a natural slope.

    Trenches need to be dug at a slight incline towards the storage collector or gutter

  4. Sand is poured into the ditches in a layer of 10-15 cm, and rubble is placed on top of it.
  5. Pipes wrapped in geotextile fabric are laid on the sand and gravel layer, connecting them with tees and crosses.

    Drains are wrapped with a layer of geotextile fabric for protection drain holes from clogging with particles of wet clay

  6. The network of canals is tested after waiting for rainy weather or specially watering the area with water from a hose, and assessing the rate of water outflow (slow removal of excess moisture is a sign of a lack of side trenches).
  7. The laid pipes are covered with sand and covered with a layer of previously dug earth, forming a small bump in the center (in case of soil subsidence), which will disappear over time.

    From above, the ditch is covered with previously removed soil, leaving a small bump on the surface to compensate for soil subsidence in the future

  8. Pipes are brought to a reservoir or well, created from concrete rings or a large plastic container.

In the future, the drainage system is supposed to be monitored - to clean the channels and pump out water from the main well.

If the drainage system is properly organized in the clay area, then there is nothing to worry about. From now on, clay in the soil will not interfere with growing plants in the garden and will allow you to keep adjoining territory clean.

Not all owners of suburban allotments are “lucky” with ideal hydrogeological conditions. Often it is only during the cultivation of the land or construction that they understand that the groundwater is high, that during the flood period there are puddles for a long time. Do not worry, this problem will be eliminated by drainage. Agree, building it is much easier than looking for a perfect site.

The drainage system will remove excess moisture from the soil-vegetation layer, which will ensure the normal growth of cultivated green spaces. She will take underground water from the foundation in case of their contact, will protect the basement and inspection pit garage from flooding.

Those who want to arrange drainage garden plot with their own hands or the efforts of a team of landscape workers, we will find detailed answers to all kinds of questions. Our material describes in detail the options for groundwater drainage systems and methods of their construction.

A drainage system that collects and removes excess groundwater is necessary in the following cases:

  1. The plot is flat, i.e. there are no conditions for the spontaneous movement of water downhill.
  2. Groundwater is marked at a level close to the surface of the earth.
  3. The site is located in a lowland, a river valley or in a marsh drained area.
  4. The soil-vegetation layer develops on clayey soils with low filtration properties.
  5. The dacha was built on a slope, not far from its foot, which is why, when precipitation falls on the site and around it, water accumulates and stagnates.

Installation of drainage is almost always necessary in areas with underlying clayey soils: sandy loam, loam. During the period of abundant precipitation, snow melting, this type of rock passes water through its thickness too slowly or does not allow it to pass at all.

Water stagnation at the level of soil development is associated with waterlogging. In a humid environment, the fungus actively multiplies, infections, pests (slugs, snails, etc.) appear, which leads to diseases vegetable crops, decay of the roots of bushes, perennial flowers and trees.

Due to stagnant water, waterlogging of the soil-vegetation layer occurs, as a result of which plants die in a water-saturated environment, deteriorates appearance plot. The drainage system allows you to remove moisture instantly, preventing its long-term exposure to the ground

If the problem of waterlogging of the soil is not solved, then over time, soil erosion may occur. In frosty times, the soil layers containing water will swell, which may damage the foundation, paved paths and other site improvement objects.

To check if drainage is necessary, you need to find out throughput soil layers on the site. To do this, dig a small hole 60 cm deep and pour water into it to the limit.

If water is absorbed in a day, then the underlying soil has acceptable filtration properties. In this case, there is no need for drainage. If after two days the water does not leave, it means that clayey rocks lie under the soil-vegetation layer, and there is a risk of waterlogging.

Due to the heaving of water-saturated rocks, the walls of residential structures can crack, as a result of which the building may become unsuitable for permanent residence

Holders of land in a lowland or on a steep slope face the problem when water stagnates at the lowest point, when it can be located higher as a receiving water. In this case, a storage well must be built in the lower part of the territory, into which a drainage pump must be installed. With its help, water is pumped upward with a discharge into a ditch, ravine or other water receiver.

If for disposal collected water it is planned to build an absorption well on the site, then work on its construction is performed in the following sequence:

The accumulation of melt or sedimentary water at the site leads to many unpleasant consequences... To solve this problem, drainage structures are used, the functionality of which is especially important for clayey soil that does not conduct moisture well. Step by step guide on the installation of a drainage system with your own hands, read below.

Drainage for clay soil

Before organizing drainage in an area with clay soil, it is important to know the characteristics of such soil. A small test is carried out beforehand. To do this, you need to dig a hole about 60 cm deep, pour 6–7 buckets of water into it. If after a day the moisture is absorbed into the soil without residue, then the site does not need a complex drainage system. In this case, a storm drain or backfill drainage is sufficient. Clay soil does not completely absorb water and therefore the site requires more careful arrangement.

As a result of the fact that clay does not conduct moisture well, accumulations of water and puddles form in the upper layers of the soil. Excessive humidity leads to the destruction of the foundations of buildings, the death of plants and the creation of a too humid atmosphere in the territory. Therefore, drainage is necessary and allows you to drain the clay soil, preventing unpleasant consequences.

For the organization of drainage, factors such as:

  • the amount of incoming moisture in the form of precipitation, melt water, automatic irrigation, etc .;
  • the area of ​​the territory in need of drainage;
  • financial capabilities that determine the type and quality of materials used for drainage.

The combination of buried and surface drainage allows the soil to be drained, providing normal conditions for plants and preserving buildings. At the same time, the buried option involves digging deep ditches, the use of pipes, gravel, geotextiles, and the construction of a well for the diverted water. All this requires financial costs and requires careful calculation of parameters.

Surface drainage is a shallow channel that is directed towards a well to collect water. On top of the grooves are covered with gratings and are easy to use. The system of such ditches does not require the use of pipes, since special material is laid on the bottom of the trenches. Thanks to this, moisture is transported into the well, and does not remain on the clay soil.

The combination of surface and buried systems is optimal for clayey soil. Each option requires the development of a diagram, which indicates the location of the ditches, wells and other elements. In this case, it is necessary to take into account the sequence of installation stages, because the drainage must perform its function quickly and efficiently.

Drainage device

To drain clay soil, surface and buried drainage is used. The first option can be of the tray type or with a sand cushion. In any case, trenches are dug towards the well to collect water. The width of the ditches can be about 30 cm, and the depth is up to 50 cm. At the same time, a slight uniform slope towards the well is observed. This is not necessary for areas with a natural slope.

For a tray surface system, special boxes or plastic trays are installed in the trenches, along which water will be transported to the well. In the case of a sand cushion, a small layer of sand should be poured onto the bottom of the ditches, the size of which is slightly larger than with the tray method, and then crushed stone almost to the edges of the depression. On top, you can pour multi-colored gravel or lay a layer of turf.

Recessed drainage involves the creation of ditches in which layers of rubble, pipes for drainage, geotextiles are laid. In the allotted place, a well is installed in a recess to collect water, pipes are laid in the trenches on a layer of sand and geotextile, and then rubble is poured and the edges of the canvas are wrapped. The well must be located in extreme point plot, and all the ditches are directed towards it.

Drainage scheme

Before starting work on the creation of drainage, the location of all elements of the system should be noted on the site plan. The well should be located in the far corner, the ditches run along the perimeter of the house or other structures, connect into one trench and lead to the well. When planning a deep system, it is worth considering that pipes cannot be laid in clay soil where heavy equipment and cars are driving. As a result, the soil will sag and damage the drainage. That's why the best option is a surface dehumidification that facilitates the rapid removal of moisture.

The diagram indicates the direction of each trench, as well as the slope of the ditches. If the site is located on a slope, then it is enough just to dig ditches of the same depth all the way to the well. On a flat surface, the slope is calculated taking into account the norms.

The slope of the pipes is indicated by fractions, which are difficult for an uninformed person to understand. For example, 0.007 or 0.02. In fact, these numbers mean the ratio of the desired slope of the pipe to its length, expressed in meters. If you need to set a slope of 0.007, this means that for 1 linear meter of pipe, the height difference should be 7 mm. And if the slope is 0.02, then on one meter the height difference will be 2 cm. Such a difference in slopes arises from the fact that for pipes different diameters different minimum slope required. And the larger the diameter, the smaller the slope. For example, for branch drains, pipes with a diameter of 9–11 cm are always used. Minimum slope for them is 0.02. This means that the slope of each meter of the drain must be at least 2 cm.

After calculating all the parameters, materials are selected and a drying unit is mounted. For surface drainage, plastic trays are used, which are installed taking into account the required slope and direction.

Do-it-yourself drainage of the site on clay soils - step-by-step instructions for the installation of various systems

Drainage of a surface type can be organized with your own hands, using a diagram and choosing materials. Simple system, consisting of trays, a well and other elements, will provide timely moisture removal. Surface drainage is supplemented with deep or backfill drainage, which enhances the efficiency of drainage.

Deep drainage: step by step instructions

Pipes will be needed to create deep drainage. For the main line, elements with a diameter of 110 mm are used, and for additional ditches, pipes with a diameter of 60 mm are optimal. The well is constructed from concrete rings or a special polymer container is inserted into the recess. Crushed stone of fraction 20-40, coarse sand, geotextiles are also necessary to create a drainage complex.

The complex of works includes the following actions:

  1. For a well, a hole should be dug, the depth of which is 2-3 m. Concrete rings set from the very bottom. The finished container is mounted in the same way. Sand is poured at the bottom with a layer of 20 cm, and then crushed stone by 30 cm. There should be holes for incoming pipes in the rings or walls of the finished container. The height of their location is equal to the depth of placement of pipes in the ditches, that is, from the upper edge about 100 cm.
  2. Next, you need to dig trenches according to the scheme. Their width is 50 cm, and their depth is 120 cm in the main highway and 100 cm in the side ones. The main channels reach the well, while the slope is 5 cm per 1 running meter pipe length. At the bottom of the ditches, sand should be poured with a layer of about 20 cm, and then geotextiles should be laid. The edges of the canvas should be higher than the edges of the pit. Next, crushed stone is poured in a layer of 20 cm, perforated pipes are laid in compliance with the slope.
  3. Docking of pipes to each other is done by coupling or socket connections... In the area of ​​bends and on straight sections, a revision well must be installed every 25 cm. The height of such elements should ensure their rise above the soil level. Revision wells are necessary for monitoring the condition and cleaning the system.
  4. Crushed stone should be poured onto the pipes so that the filter material completely covers them. Next, the geotextile is wrapped. The space remaining in the trench is covered with sand, and a layer of turf or decorative gravel is laid on top.

Surface drainage installation

Deep drainage is designed to remove moisture from the soil, and the surface system helps prevent stagnation of water in the upper layer of clay soil. Rain moisture or melt water is immediately discharged into the well, transported through special troughs. This allows water to be removed from the roof of buildings and to avoid the appearance of puddles in the area with clay soil.

For a surface system, it is necessary to mark on the site plan the direction of the ditches that should lead to the well. The slope is the same as for deep drainage. Then the following actions are carried out:

  1. According to the scheme, small trenches are dug, which are well tamped. It is necessary to observe the slope of the ditches towards the well or catchment areas. If the site has a natural slope, then the depth of the channels can be the same. The depth of the trenches is up to 80 cm, and their width is 40 cm.
  2. Sand is poured into the bottom of the trenches with a layer of 10 cm, and then the same amount of crushed stone of fraction 20-40. Next, you need to pour on the filter material concrete mortar and immediately install trays for water removal.
  3. Sand traps should be installed at the end of each line of gutters using the same installation method as for gutters. Storm water inlets under the downspouts of buildings are mounted using the same technique. All parts are well connected to each other, forming a single system. Next, the trays need to be covered with special grates on top.

Drainage operation

The correct organization of any type of drainage system is the key to comfort on a site with clay soils. Quick removal of moisture after rain avoids the formation of puddles, high humidity air and destruction of the foundation of buildings. And also drainage is practical in an area where there are plants that do not tolerate stagnant water well. In this case, you should provide drainage ditches around these plants.

During the operation of the deep and surface versions of the systems, it is necessary to regularly clean up debris, leaves, grass and sand. This keeps the drainage efficient. And you also need to take into account the following operating features:

  • revision wells, sand traps must be regularly cleaned of contamination;
  • damage to buried pipes requires their timely replacement;
  • before completing the installation of the structure, it is necessary to check by pouring several buckets of water into pipes or trays. Moisture should quickly enter the main well;
  • in clayey soil, pipes must not be laid in areas subject to heavy loads.

To create drainage with your own hands, you should use only high-quality pipes and trays, durable geotextiles, medium-sized crushed stone and coarse sand. It is important to fix couplings and other connections carefully to avoid moisture leakage in the wrong place.

Video: how to make a drainage storm

For a site on clay soil, a drainage system is necessary, since it allows you to eliminate excess moisture. Wherein clay soil can settle, which requires careful design of the pipe layout.

The work on the manufacture of this type of drainage is quite laborious, because it is required to select a large amount of soil and then fill in crushed stone and sand in its place.

To properly make drainage around the house, you should start making it with markings. For this, the perimeter is measured and a rope or construction cord is pulled along its edges. After that you can start to sampling... Since insulated slab foundation is a shallowly recessed structure, the depth of soil sampling should not exceed 0.5 meters. As a rule, only the fertile soil layer is removed. Further, to the bottom of the pit geotextile is laid and wraps around its edges. After that, they start backfilling and tamping. sand pillow ... It is necessary to ram the sand using a mechanical vibrator. After a layer of sand, it is poured into the pit, leveled and rammed rubble.

Simultaneously with the laying of crushed stone, along the perimeter of the pit, drain pipe in compliance with the required slope. Inspection wells are installed in the corners of the future foundation, which are necessary for servicing the system. The slope of the drainage pipe must be at least two degrees.

As a result, it should turn out that the drainage pipe is inside the crushed stone layer. If necessary, pipes can additionally be laid in several more places, this will strengthen the protection of the foundation from moisture.

A receiving well is installed at the outlet of the pipes of the drainage system. This completes the work with the drainage system and you can start and further work for the construction of the foundation.

The main mistakes in the manufacture of drainage

To properly drain the foundation, you need to know the main mistakes made during its construction.

The most common mistake during the construction of a drainage system, it is combining it with gutters coming from the roof of the building. This cannot be done for the simple reason that in autumn period, with a large amount of precipitation, the drainage system may not cope with the removal of a large amount of water and begin to work in the opposite mode.

This will certainly affect the moisture content of the soil and it will turn out that all the work on drainage and drainage of the site will be in vain.

The second frequent problem, this is non-observance of the required drainage slope... As a result, the system is constantly clogged and cannot function normally.

Third is application drainage pipes without additional filter winding, which also affects the timing of the clogging of the system.

Output

Self-fabrication of the drainage system is beneficial only in the case of deep ring drainage, made along the outer perimeter of the finished one, since the work on its implementation does not require the use of special equipment.
In the case of reservoir drainage, all work is much more complicated and requires certain skills from the master, as well as the availability of special tools such as a level and vibrator.
