Most effective way to protect the foundation of a private house from the destructive effects of ground and storm water is a high-quality drainage system. What is especially important when water accumulates in the upper layers of the soil, as it can provoke flooding of the basement or basement, moistening and deformation of the walls, as well as the occurrence of fungal formations. The article will discuss how to lay drainage pipes.

Pipes for the drainage system, which are installed around the entire perimeter of the site, allow you to create a high-quality drainage system. After all, the danger of flooding is not only groundwater, but also floodwaters. Damage can also be caused by precipitation that exceeds permissible limits.

Unlike foundation waterproofing, the drainage system can be laid even after the construction of the house, if there are grounds for this. But under certain conditions, it is better to install on initial stage construction. This requires the following reasons:

the gently sloping location of the site, contributing to a significant accumulation of water;
clay and loamy soil, which have poor culvert characteristics;
statistics of exceeding the level of precipitation characteristic of the area in which the building is located;
elevated groundwater level (less than 1.5 meters to the ground surface).

In addition, it is worth focusing on the depth of construction of the remaining buildings on the site. The presence of a deep foundation next to the main building not only prevents the natural outflow of groundwater, but also contributes to its accumulation, thereby increasing the risk of flooding. The barrier for free circulation of water are also equipped on the site concrete blind areas and asphalt pavement. In such a case, it is considered competent to connect storm drains to the main drainage system.

To prevent the consequences of changes in the level of groundwater and the accumulation of moisture in the soil around the building, laying a drainage pipe will allow.

Types of drainage systems

There are two main options for designing a drainage system:

Open (surface)- used to remove excess moisture resulting from the accumulation of precipitation or melt water. The open drainage system is presented in the form of ditches and trenches.
Closed (deep)- perforated pipes are used in laying, which are laid to a certain depth in a previously prepared trench. The main function is to drain groundwater and protect the foundation of the house.

Materials required for laying a closed drainage system

The process of installing a drainage system is quite laborious and requires thorough preparation. From bulk building materials will need:

Sand. AT drainage works river sand is mainly used. Its main function is to create a filtration cushion around the drainage pipe.
rubble. To equip the system, you will need a medium and large fraction. The purpose of crushed stone is to form a stable layer to prevent the penetration of dirt and large parts of the soil. In addition, crushed stone prevents excessive soil pressure on the corrugated pipe.

Main materials:

drainage pumps. They are used only in case of significant flooding of the site with groundwater. Contribute to mechanical drainage;
drainage pipes. With their help, the main drainage system is formed. The number and diameter depends on the complexity of the bookmark scheme. Most often, plastic pipes are used for drainage;
geotextile- protects the drainage pipe from soil contamination. As a rule, interlining or dornite is used. In addition to strength, both types of textiles have a filtering ability;
couplers- necessary for attaching drainage pipes to each other.

As a rule, the drainage system needs periodic cleaning; for this, manholes are installed along its perimeter. And to collect water in the system, a collector well is mounted.

Selection of drainage pipes

Before starting the installation of the drainage system, special attention should be paid to the choice of pipes for work. The first thing to consider is the use of perforated pipes in the arrangement of the drainage system. The second is the diameter and the presence of holes for the outflow of moisture and air exchange. And no less important point is the material from which the pipes are made.

Currently, the following types of pipes are presented on the building materials market:

asbestos-cement;
ceramic;
from polymeric materials.

The most popular in the arrangement of the drainage system are polymer drainage pipes. Their advantage over other species is as follows.

Long service life - up to 70 years.
High levels of strength.
Resistance to corrosion processes and exposure to aggressive environments.
Reduced weight indicators that simplify the process of transportation and installation.
Self-cleaning ability due to smooth surface.
Silt resistance.
Value for money.
Ease of maintenance. Thanks to the geotextile filter, the system does not need to be flushed.

Drain pipe diameter:

up to 150 mm - for a drainage system that drains a small amount of water;
up to 300 mm - for systems with a high load.

For an extensive drainage system, you will need pipes of both small (for branches) and large diameter (for the main branch of the system).

Plastic drainage pipes

Polymer pipes, which are usually used for styling drainage systems, are made of PVC, polypropylene or polyethylene and are represented by the following types:

single layer or double layer. The choice of the number of layers depends on the density of the soil;
flexible and rigid. Rigid pipes are applicable for simple circuits drainage, while flexible ones allow you to create complex branching throughout the site;
pipes with or without filter jacket. As a rule, drainage pipes already have holes along their entire length. But if there are no special holes in the purchased material, they can be made independently using a drill and a thin drill;
corrugated or smooth.

As for geofabric coverage, as a rule, samples already covered with filter textiles are presented on the building materials market. When buying uncoated pipes, you can wrap their surface yourself by securing the material with a rope or thin wire around the perimeter of the pipe.

Drainage pipe laying design

Before starting work on the installation of a drainage system, it is worthwhile to first draw up a plan for its location on the site.

This requires taking into account the type of soil and the height of groundwater. The branched scheme is most often used, at the junctions of which manholes are installed.
The distance between the branches directly depends on the type of soil. For clay soil, it is 10 meters, for loamy soil - 20 meters, with sandy soil type - 45 meters.

Laying drainage pipes with your own hands

First you need to determine the location of the drainage system. There are only two accommodation options:

"wall" drainage - passes only near the foundation of the house and prevents moisture from entering directly into the building itself;

the drainage system, located around the entire perimeter of the site, protects not only the basement of the building, but also other outbuildings and plantings located on the territory.

Stages of work

The first step is to mark the site for the placement of drainage ditches. To facilitate the process, you can use a special laser rangefinder. Particular attention should be paid to places where moisture accumulates after rain - this means that water exchange is difficult in this area due to the density of the soil or the presence of obstacles.
Trench. The recess under the drainage trench must be carried out taking into account the height differences. The main task of the prepared ditch system is the rapid and unhindered outflow of water.

Tip: during work, you can use a watering hose by running a certain amount of water - make sure that water does not accumulate in certain parts of the trench.

Before installing drainage pipes, the bottom of the trench must be carefully tamped. Then any filter material is laid, while its ends should extend beyond the trench. Next, river sand and crushed stone are poured, first large, then medium fraction, to a thickness of no more than 20 cm.
Drainage pipes cut according to the dimensions of the circuit, using a jigsaw or special device- pipe cutter. Next, start laying pipes, connecting the joints with fittings. In order for the junction to be strong, it is necessary to dock the parts after preheating the docking sections.
Pipes must be carefully wrapped with geotextile, securing the joints with a rope or thin wire. The choice of such a material is not accidental, since it must pass the water coming out of the perforation. In addition to the throughput, the function of geotextiles is to protect the perforations of the pipe from clogging.

Pipe laying must be done at a slope, connecting the ends to manholes. Two types of wells can be used in the system: sealed, allowing the use of collected water for technical purposes, and absorbing - the water will go back into the soil. The slope of the drainage pipes depends on its diameter, the larger it is, the less slope is required.
The next step in the installation of drainage pipes will be filling the surface with crushed stone and sand. After that, the structure is wrapped with sheets of filter material located on the surface and covered with a layer of soil.

Maintenance of the drainage system

In arranging the site with a drainage system, not only its thoughtful and high-quality installation is important, but also compliance with the operating rules. This will extend the life of the system for as long as possible.

Approximately once every four years, it is mandatory to inspect the condition of pipes and wells, as a preventive measure. In addition, once every two years it is worth measuring the water level in the wells, its significant change may indicate the following factors:

damage to the integrity of the pipe;
the formation of a dense blockage;
the growth of silt deposits on the entire surface of the pipe;
partial settlement of the pipeline due to soil movement.

In order to avoid such problems, it is necessary to timely inspect the drainage system and clean it from various kinds of pollution.

Errors in the laying of the drainage pipe

The effectiveness of drainage directly depends on the quality of the installation. Any violations during operation contribute to the disabling of the system. In the best case, you can repair the damaged area, in the worst case, you will have to completely reinstall the drainage system.

The most common mistakes include:

selection of the pipeline system without taking into account the quality of the soil. For example: on loamy soil it is not recommended to use pipes without a filtration system;
violations associated with a change or absence of the angle of inclination of the drainage system;
initially, the option of draining water from the well was not provided;
the technology for arranging drainage pipes is not observed - the installation was made without filtering dumping of crushed stone and sand;
lack of geotextiles and filter material;
poor-quality soldering of pipes;
no perforation.

Choosing the type of drainage system, it is necessary to be based on the location of the site and the quality of the soil. For self-arrangement of drainage, it is necessary to plan in advance the layout of the drainage. When choosing materials, preference should be given to the most practical and durable. These include plastic corrugated pipes with perforation. Observing all the stages of laying the drainage system, you can get a high-quality drainage system. In addition, drainage guarantees the protection of the basement or basement of the house from the harmful effects of groundwater.

This is a communication system that is laid below the soil surface and contributes to the diversion of groundwater into a special well or into a ditch outside the site. Thanks to this solution, it is possible to avoid flooding of basements and cellars, rotting of plantation roots and regular formation of puddles.

First of all, pipes for drainage of the site are divided into groups, the products in each of which differ in the type of material:

asbestos-cement;
ceramic drainage pipes with perforation along the entire length of the products;
polymeric.

But for some time the first two species have practically gone out of use, because The popularity of plastic analogues is growing rapidly. The disadvantages of asbestos-cement and ceramic products quite eloquently explain this state of affairs:

Excessive weight, which makes it very difficult not only to transport the material, but also to install the drainage pipe. To do this, you usually have to use special equipment.
Difficult pipe laying technology with the need for perforation. As a result, it is extremely difficult to independently carry out installation.
Relatively short service life (average 20-30 years).

Polymeric communications are found in two versions: uncoated perforated pipes for drainage and wrapped in filter material. If a filter is used, then a higher degree of efficiency of the system is noted, since a special material traps large and small particles of contaminants, sand, which, in turn, significantly reduces the likelihood of an early silting of the pipeline from the inside.

Polymer communications are also classified based on differences in the source material. It could be polypropylene, polyethylene, polyvinyl chloride (PVC) products. Polyethylene versions are found in two variations: high and low pressure(PVD and HDPE). In terms of popularity, polypropylene products lose somewhat, but only slightly.

There are polymer pipes for drainage of the site according to their design features:

single-layer executions;
two-layer.

Each of these options is characterized by a certain level of ring strength. There are varieties that differ from each other in the degree of rigidity:

corrugated pipe for drainage is flexible (length varies within 40-50 m, for ease of transportation, products are produced in reels);
rigid communications (produced in cuts of 6 and 12 m).

Plastic versions of drainage pipes for draining groundwater have a number of advantages:

High strength characteristics. To a greater extent, this applies to the two-layer version. The increased degree of endurance is due to the presence of stiffeners, which contribute to the uniform distribution of the load exerted on the pipeline.
Very long service life without signs of external deformations and loss of its basic properties by the product (50-60 years).
A high degree of resistance to aggressive substances, which are often found in large quantities in the soil, as well as resistance to corrosion.
Light weight, which allows you to independently cope with the task of installing the pipeline.
In the presence of a protective filter material, the efficiency of the functioning of such communications increases.
Low cost for the arrangement of the drainage system. This is due to the absence of the need to invite specialists to install pipes, and in addition, the relatively low cost of such products is noted. Especially if you compare the duration of operation with analogues. So, in the case of asbestos-cement or ceramic communications, the pipeline should be replaced three times more often than plastic products.

In addition to all that has been said, it is quite possible to add one more positive point - wide range of, which will allow you to select pipes for the site drainage system in accordance with the requirements and operating conditions.

Choice principle

There are main criteria on the basis of which communications of this kind are selected:

Type of drainage system (open and closed), which determines the preferred type of product in each case. In this case, the presence of holes plays a major role. So, for closed systems the best option is a perforated pipe. The purpose of drainage in this case is to divert groundwater from the site. open systems designed to collect and transport atmospheric precipitation and melt water to the water intake.
The dimensions of the product, which is determined primarily by the amount of liquid that will be discharged. For simple tasks, communications with a diameter ranging from 100 to 140 mm are usually purchased; pipes up to 300 mm in diameter are used to transport large volumes of groundwater. For country houses often used drain pipe 110 in the geotextile filter.
The level of load exerted on the product (determined by the laying depth) necessitates the use of one- or two-layer versions. Recommended hardness class: SN2 to SN16.
Material. Corrugated PVC pipes for drainage of garden plots are the most popular today. Therefore, if the user wants to make the laying task easier, save money and end up with a system with a long service life with high strength characteristics of the pipeline, then this option will be the best solution.

In addition to all that has been said, the operating conditions should also be taken into account. In the case of stony soil, geotextiles are not used. In all other situations, there are no restrictions on laying the filter material, and during installation, a corrugated perforated drainage pipe with can be used.

Installation instructions

Before starting work, a pipeline layout plan is drawn up. The "herringbone" option is usually used. The distance between communications is affected by the type of soil: for sandstones, the distance between the "branches" of the drainage system from each other corresponds to a value in the range of 45-50 m, in the case of preferably clay soil, the distance reaches 10 m, for loamy soil - 20 m.

When is it planned to lay pipes for drainage and storm sewer you must follow the following instructions:

A trench up to 1.5 m deep is dug along the walls of the house, which is mainly determined by the level of groundwater. The width of the ditch should exceed the size of the communications by almost half a meter. During operation, we must not forget about the slope of the drainage pipe for unhindered outflow of water.
A sand and gravel cushion 10-20 cm thick is laid at the bottom of the trench.
Geotextiles are spread, on top of which crushed stone is again poured.
Pipe laying is carried out taking into account the slope at the rate of 2-3 cm per meter.
In the areas of joints and turns, revision wells are located.
Communications are covered with gravel, on top of which the edges of the geotextile laid earlier on the bottom are laid.

At the final stage, the entire structure is covered with sand and soil. The result is a protected drainage system. And taking into account the use of polymer communications, the need for frequent replacement of pipes is reduced. Accordingly, the resulting structure can remain intact for a long period.

Thus, if as suitable option plastic pipes for drainage are considered, the price of such products is not so high (on average from 60 to 200 rubles / meter), and the quality of the system will be excellent. This is determined by the high strength characteristics of communications, long service life, resistance to aggressive environments. Not the last role is played by a wide range of polymer pipes, which will allow you to choose the option that is most suitable for the diameter, type and type of material.

If signs of stagnant water appear on the site: plant roots rot on the site, puddles after rain long time do not dry out, the ground constantly remains wet, ice forms in winter, and mold forms on the walls of the basement in the house, which means it is necessary to lay drainage pipes under the ground for drainage.

Drainage pipes or drains are containers that serve to remove excess moisture from any piece of land.

Drainage systems from pipes - are considered more modern and convenient, because they are located underground, do not violate appearance area and do not cause injury.

There are two types of drains: collecting moisture and draining.

The first type is distinguished by the presence of perforation - small holes through which water from the soil enters the drainage system. Such pipes are laid at an angle along the perimeter of the site or over its entire area. They carry excess water to drainage wells.
The outlet drains do not have perforations. Water does not get into them from the ground, but from a drainage well. They do not collect moisture, but divert it from the well to specially designed places. Often such places are special collectors or ditches, natural reservoirs and cesspools.

There are pipes that not only collect water, but also filter it.

Some types of soil, for example, those containing crushed stone, themselves have a filtering ability. With such soil, clean water enters the drainage system, and it is not necessary to install drains with filters.

Otherwise, for example, if the soil consists of clay or loam, pipes without a filter will quickly fail.

Note! A special winding made of geotextile or coconut fiber serves as a filter. Thanks to an additional layer between the soil and the pipe, only water enters the drainage system. This is important because the more impurities the water contains, the more often the drain pipes will have to be cleaned.

Types of drainage systems

There are many varieties of both pipe and pipeless drainage systems.

This article discusses groundwater drainage pipes: a complete classification of drainage products, their advantages, characteristics and main parameters are presented. Thanks to this information, you will learn how to select the appropriate types of pipes for certain types of drainage systems in accordance with their requirements, soil conditions, etc.

Groundwater drainage pipes: an introduction to the topic

The drainage pipe acts as the main building element, on the basis of which a drainage system is formed, designed to drain areas. This element is responsible for collecting and diverting groundwater, melt and rainwater outside the territory with their preliminary filtration.

Installing large diameter drainage pipes allows you to cope with problems such as:

increased soil moisture;
mold formation;
flooding of the site, the foundation of a residential building and buildings for household purposes, as well as cellars;
permafrost formation;
the appearance of puddles on paved surfaces;
formation of ice on footpaths;
rotting of the roots of garden flowers, vegetable crops and other vegetation due to an excess of moisture in the garden and suburban areas.

Features of drainage pipes with partial perforation, full or no perforation

If we talk about general classification products for drainage systems, the range is represented by the following types of pipes (by type of material):

asbestos-cement;
ceramic;
plastic drainage pipes with and without perforation, as well as with its partial presence.

However, most construction companies have already abandoned the use of pipes made of ceramic or asbestos cement due to the numerous disadvantages inherent in them:

Large weight, requiring significant costs for transportation and installation, because the installation of such dimensional products cannot do without the use of specialized construction equipment.

The slow process of installing a drainage system, which can only be carried out by the hands of professionals.

Low performance. Drainage pipes without perforation are usually on sale, so the holes are made manually. Because of this, during operation, the pipeline clogs faster, so frequent cleaning is required, and in some cases a complete replacement of elements.

The construction of systems based on them is much more expensive than in the case of using plastic elements.

Comparative pricing table:

Advantages of plastic drainage pipes: HDPE and PVC

Polymer products (plastic) are in many ways superior in performance to asbestos-cement and ceramic products for drainage.

List of their advantages:

Long service life.
High strength index.
Complete immunity to corrosion.
Light weight, which facilitates not only the transportation process, but also the installation procedure, as well as speeding up the time for its implementation.
Due to the presence in the assortment of a large number of connecting elements (fittings, tees, etc.), the installation of the system is fast, reliable, and convenient.
The smooth surface prevents dirt from sticking, delaying the clogging process.
The use of drainage pipes in geotextiles of 200 mm or more eliminates the possibility of system silting.
All installation work can be done by hand, since this does not require special education, construction equipment and special equipment are not needed.

On the example of drainage corrugated pvc pipes with a diameter of 200 mm, you could see that the cost of these products can also be attributed to the significant advantages of plastic products.

The range of plastic pipes includes several categories of products:

polyvinyl chloride;
polyethylene;
polypropylene.

The most popular on the market are pipes for drainage systems made of PVC.

Features of PVC drainage pipes: product classification according to different criteria

Products made of PVC and other polymeric materials can be divided into the following categories:

two-layer and single-layer;
flexible pipes (produced in coils, the length of which is 40-50 m);
rigid products for drainage systems (their length is fixed, the assortment includes pipes from 6 to 12 m long);

products with different strength classes (letter marking SN: 2,4,6,8,16);
pipes with and without filter wrap.

Prices for drainage pipes 200 mm (with and without geotextile):

Products presented for sale can have a diameter of 50 to 200 mm. There are also more massive options related to large diameter drainage pipes.

Characteristics of perforated drainage pipes

Flexible single-layer perforated products can be used at depths of no more than 3 m. The pipe class also indirectly indicates the recommended laying depth. In the case of SN2 pipes, the depth should not exceed 2 m, SN4 - no more than 3 m.

Double-layer pipes have a smooth inner surface. In this case, the outer side is corrugated. As a rule, such products have a ring strength of SN6. When arranging the drainage system, lengths of no more than 4 m are used. Coconut fiber or geotextiles can be attached to them as a filter. On sale there are products without a filter.

Flexible drainage corrugated perforated pipes are marked with class SN8. Supplied with or without filter media. Designed for deep laying - up to 10 m. Two-layer products of the same class allow you to deepen the system by no more than 8 m. They are made without a filter.

The average price of drainage pipes 160 mm and 110 mm with perforation and corrugation (3 m):

Features of Perfocor products: products for drainage systems

Perfocor pipes are successfully used for water drainage. Perforations on their surface allow water to penetrate into the products. After that, it is transported further along sewer system or displayed in an artificial or natural reservoir.

The scope of application extends to the construction of:

buildings for various purposes;
roads;
stadiums;
airports;
as well as reclamation of agricultural land.

The connection of corrugated perforated drainage pipes Perfokor is carried out in several ways. For this, a combination of a coupling and an o-ring or butt welding can be used.

Due to the fact that the rubber gasket is placed inside the corrugation during the connection of the system elements, this part cannot move during the installation process. The rubber gasket intended for connection has the same profile as the pipes. Therefore, the possibility of pipeline leakage, as well as groundwater ingress is excluded.

Specificity of corrugated perforated drainage pipes with geotextile

As an effective addition to the pipeline, increasing the terms of its operational service, are used different kinds filters. These materials include geotextile fabric and coconut fiber.

Corrugated perforated drainage pipes with geofabric 160 mm or more are products with a large number of rationally located holes, as well as stiffeners. These small holes are placed in the depression that forms between the corrugations.

The stiffening ribs ensure an even distribution of the pressure exerted by the soil on the pipe. Due to the fact that the load is distributed over the entire length of the pipe, the drainage system can withstand not only soil pressure, but also all additional loads that arise.

These types of pipes are used for laying pipelines at a depth of 0.7-6 m. a large number holes, which fall on 1 m. p. on a special profile of the product, water is quickly collected, passed through the entire system and discharged outside the suburban area.

Diameters of drainage pipes and features of the use of their elements

If you undertake to create a drainage system on the site with your own hands, you should take into account the following recommendations:

The effectiveness of the system depends on how correct your choice of pipe diameter is.

A perforated product with a diameter of 110 mm is capable of draining a section from water within a radius of 5 m. This information should be taken into account when designing a drainage layout.

Pipes must be laid with a slope in the direction where the well or septic tank will be installed.

The process of connecting all elements of the pipeline must be technologically correct.

Pipes with a diameter of 63 mm are used on a par with 110 mm products. Each such element has a network of small holes.

Experts recommend buying a drainage pipe 63 in a geotextile filter for use in areas that are located in lowlands or in areas where there is a high level of groundwater. This material can be used for arranging drainage in the construction of a cellar, an underground garage, as well as modern-type cottages with a basement.

Choosing a pipe for a drainage system according to the type of soil on the site

The foundation part of any structure can be eroded by groundwater even at a depth of 1.5-2 m. Groundwater includes components that can destroy the foundation. Waterproofing in such cases is powerless, so you have to resort to more drastic measures - the construction of a drainage system. In this case, the type of soil, as well as the degree of its moisture content, should be taken into account.

An increased water content in the soil can lead to freezing and decay of plants, the appearance of fungi on them and on fruit trees, as well as to waterlogging of the territory. In this case, it is recommended to use corrugated pipes made of polyethylene. With their help, you will provide a budget and fast drainage system that will relieve groundwater pressure and significantly reduce their level.

Soil types and optimal materials:

Characteristics of 300 mm plastic drainage pipe

Plastic pipes for drainage systems have proven to be durable, reliable products. They are economical and efficient. The use of polymer products can significantly reduce the cost of electrical energy and money for the performance of work on drainage of the site. Such a system can last for 40-50 years.

The technology of arranging the drainage system involves the use of filter materials, as a rule, geotextiles.

The average price of a 300 mm drainage pipe made of polymers is 200-300 rubles / m. n. If the products do not have sockets, their cost is reduced by about 50-100 rubles. In drainage systems, similar options for cast iron pipes are used. Their cost is in the range of 350-450 rubles / m. P.

Regardless of the size of the products, the system is always installed at an angle and in each case it is worth adhering to certain parameters. Installation of pipes with a diameter of 300 mm is carried out with a slope of at least 3 mm. Since this type of product can meet the stiffness classes SN6 and SN8, the pipeline can be laid to a depth of more than 2 m.

Characteristics of large diameter drainage pipes for a ditch

The choice of pipe diameter also depends on the inflow of groundwater. In other words, the selection of products for the drainage system is based on an indicator that reflects the amount of water that passes in 1 second.

Other factors come into play here:

groundwater level;
the amount of excess moisture;
nature of the landscape.

Corrugated PVC drainage pipes with a diameter of 500 mm, 400 mm and 630 mm are two-layer products. Their double walls have a corrugated coating on the outside, and their surface is smooth on the inside.

Due to the presence of corrugations, the pipe walls exhibit high resistance to the occurrence of any deformation changes under the influence of loads. In the assortment of the modern construction market, you can find products corresponding to the following classes of ring stiffness:

SN16.

This diversity allows you to lay the pipeline at different depths. Polymer pipes of large diameters have a wide range of operating temperatures. Extreme points correspond to -40°С and +60°С.

The average price of drainage pipes 400 mm, 500 mm and 630 mm (Perfokor):

Work on the construction of a drainage system on the site is most often carried out simultaneously with its development. In order for the drainage system to function, it is necessary to organize the maximum flow of water to it. The indicator that determines the access of moisture to the pipeline is called the permeability of the soil. To increase it, sprinkling with special filtration materials is used.

These materials include:

gravel;
crushed stone;
pebble.

Thanks to the filter, the volume of liquid from the area entering the system increases. So that the drainage system is not filled with silt and dirt, the speed of water flow through the pipes must be at least 0.2 m / s.

Common mistakes when laying a drainage system:

the use of pipes that are not intended for installation in a certain type of soil (for example, the use of a pipe without a geotextile filter on loamy soils);
lack of filtering dusting;
lack of necessary slopes;
backfilling trenches with non-filtering soil;
untimely removal of accumulated liquid from the collection well.

The effective operation of the drainage system depends not only on compliance with the installation technology, but also on Maintenance pipeline during further operation.

Drainage maintenance involves regularly checking the system for blockages and malfunctions, and eliminating them if they are detected. In addition, it is systematically necessary to monitor the state of the groundwater level in the territory of a suburban area in order to know how effectively the sewage system copes with the removal of excess moisture. It also does not hurt to check the quality of groundwater.

Due to the timely implementation of scheduled repair and preventive maintenance, as well as troubleshooting, you can not only increase the life of the pipeline, but also eliminate the likelihood of accidents.
