How to make a foundation drainage

Starting work on building a house, you need to have an idea about all stages of construction, including how to properly drain the foundation. It is the quality of the foundation that determines the reliability of the entire structure.

The drainage system is used to strengthen the base with an unfavorable type of soil, or in conditions of frequent precipitation, and there are two types:

  • near-wall;
  • ring-shaped.

Wall drainage system

It is necessary for removal of thawed, ground and other waters and protection of a design against their harmful effects. With a high-quality drainage installation, the building's service life increases significantly, since it prevents the accumulation of moisture, mold and other adverse factors that lead to the destruction of the house.

Wall drainage is an angled system consisting of closed pipes. The corners of the structure are equipped with manholes. Wells are necessary to eliminate blockages that may occur during operation.

Hydrostatic and mechanical pressure of the soil water on the foundation is removed with the help of drainage.

Ring drainage system

This drainage system is not mounted at the surface of the walls, and at a certain distance from them (about 3 m). This drainage is used in the absence of the possibility of using the wall type and the installed blind area.

In the absence of waterproofing of walls, or in the presence of a reinforced concrete base, it is worth making a choice in favor of wall drainage, otherwise you will not get the desired result.

Consequences of the absence of drainage

The presence of a drainage system is simply necessary, otherwise the impact of moisture on the base of the house will lead to its destruction. The consequences will appear gradually in the form of a skew of the walls, roof and the whole structure. That is, over time, the probability of falling home is high.

Pipes for drainage

There are a variety of materials for building a drainage system that are sold in hardware stores. The most used are corrugated polyethylene pipes that bend well. The walls of such pipes are equipped with holes (perforations) necessary for the passage of water into them and further ingress into the sump.

The pipe is laid at a depth of 3 meters, and its service life exceeds half a century. They are mounted both before waterproofing, and after. The diameter varies from 5 to 20 cm.

If there is a large possibility of foreign particles penetrating into the pipe, and, consequently, there is a high probability of blockages, additional winding is required from the geopolit.


How to make a foundation drainage Geotextiles Geotexil has recently been rapidly gaining popularity in the construction industry. It is produced using a woven or non-woven method of polymer fibers. Since the raw material is environmentally friendly, then the final material is environmentally friendly.

Geofield has a number of the following advantages:

  • resistance to chemical attack;
  • lack of reaction resulting from thermal oxidation;
  • not rotting , mold and fungal diseases;
  • due to its structure, geopolitically protected from rodent attacks and plant germination.

This material is used in cases where filtration, separation, drainage and protection of the drainage system is necessary.

Independent installation of the drainage system

How to make a foundation drainage Ring drainage When thinking about building your own house, it is necessary to provide a drainage system, otherwise the lifetime of the structure will be minimal.

This task should be approached with the utmost responsibility and all work should be entrusted to specialists. However, acquiring the necessary theoretical base, you can cope on your own.

  1. A sand cushion is made at the bottom of the ditch;
  2. Pipe installation is carried out at an angle of 1 cm per meter;
  3. Pipe cutting is performed with a hacksaw, then the sections are joined using a press fit and seal the joints with glue followed by winding with electrical tape;
  4. Having laid and formed the pipeline, the ditch must be filled with 30 cm of fine fraction gravel, then a layer of filtering geopolit is spreading;
  5. a collector that attaches to drain pipes with with the help of fittings;
  6. The last stage is the tamping of the upper soil layer covering the entire structure. If there is a likelihood of abundant water flows, it is necessary to provide a gravel mound of large or medium fractions.

At this drainage works are considered completed, and in the future you can not worry about the security of your own home.
