A drainage device in the area near the house helps prevent soil flushing, the formation of excess moisture, improve air permeability of the soil (the soil becomes drier, loose, while maintaining its nutrients). Drainage construction perfectly contributes to increased soil fertility and protection excess moisture at home. Each owner of a country cottage or a country house thinks about the device of a drainage system, since it is known that the foundation of any building even at a relatively shallow depth (1.5–2 m) regularly exposed to groundwater, which ultimately may lead to the destruction of the foundation of the building.

Types of foundation drainage

Surface wall drainageSurface wall drainage

The most traditional and inexpensive drainage method are the good old ditches. This method is typical for the flat terrain and lowlands, that is, where it is difficult to make a slope for flow water. The lack of drainage ditches include their unpresentability and that they are destroyed over time, overgrown and clog up.

In addition to the ancient ditches, two more approaches to the device are known. drainage wall systems:

  1. Superficial wall drainage. For his devices need to make a preliminary planning of the site, including work to create slopes from buildings, pits and trenches. Surface drainage is mounted at a distance from buildings.
  2. Deep wall drainage. In this case special pipes and materials are used to equip drainage in close proximity to the foundation of the walls of the building (along perimeter).

Deep wall drainageDeep wall drainage

Today, wall deep drainage foundation is considered the most effective. Its main function is to prevent flooding of the foundation of the house and its basement premises.

Area drainageAreal drainage

Drainage systems for the location of the pipes are divided into the following types:

  • Contour (to protect the foundation of the house);
  • Areal (to protect the site);
  • Bilinear;
  • Single line.

Contour drainage systemContour drain system

Contour drainage is popular. system. Pipes are placed around the perimeter of the protected structure, close enough to all the outside sides of the foundation of the house. IN this drainage system includes corrugated perforated pipes, special structures for water discharge and drainage wells. A gravel and sand filter is created around the perforated pipe. Stiffeners contribute to an increase in safety margin in cross-section along the entire length of thin-walled pipes, which allows they, while remaining light, withstand decent loads at a depth of 10m The drainage pipes should be installed with a small bias.

Modern drainage pipes are made of polyvinyl chloride diameter from 5 to 20cm. Perforation of drainage pipes does not allows penetration into the material used for sprinkling drainage system. The area of ​​the holes should not exceed 0.5% of pipe surface area. Due to a number of advantages that have appeared not so long ago in the construction market polymer drainage pipes radically influenced the arrangement of drainage systems. Plastic the pipes are strong and light, flexible and at the same time rigid. Stack drainage system made of PVC pipes can be up to a depth of 8m. Because the drainage polymer pipes, while in the ground, are fully protected from sunlight, this significantly increases the period of use polymer drainage (over 50 years).

The depth of the drainage device is determined by your requirements for groundwater reduction level, as well as the type and system of drainage. Often enough surface drainage is enough, only choose the right waterproofing and correctly apply it. Waterproofing is also used when sealing joint joints and joints of pipes and wells.

Granite rubble or gravel.

Crushed stone with sand and gravel is not suitable for dusting the drain, since under the influence of water they can clog soil voids and holes in pipes. Dimensions filter particles should be larger than 10 times larger particles of soil.

Drain wellDrainage well

The purpose of the drainage wells is to monitor the working drainage work and cleaning of drainage routes.

The location of the wells should coincide with the points of change diameter, direction and slope of the drainage pipes. They usually located at the lowest point of the infield.

Drainage wells are prefabricated plastic elements. Inside the wells, layers of rubble and sand or broken brick, and on top of the formed layer lay sod, which it is necessary to protect the backfill from the formation of a layer of sludge. By technology surplus water discharged into the drainage well should go into the lower soil layers through backfill, or pump out beyond the boundaries of the development site with a drainage pump.

Experts recommend simultaneously with drainage work to carry out installation of various engineering networks.
