- Types drainage foundation
drainage device in the area near the house helps to prevent soil erosion, the formation of excess moisture, improve the air permeability of the soil (soil becomes dry, friablewhile maintaining its nutrients).Construction of drainage perfectly increases the level of soil fertility and protecting the house from excessive moisture.Every owner of a country cottage or country house thinks about the device drainage system, since it is known that the foundation of any building structure, even at a relatively shallow depth (1.5-2 m) on a regular basis is adversely affected by groundwater, which eventually can lead to the destruction of the building foundation.
Types drainage foundation
trim surface drainage
most traditional and low-cost method of unit drainage ditches are the good old days.This method is typical for the plains and lowlands, that is, where it is difficult to make a slope for water drainage.For lack of drainage ditches carry th
addition ancient canal, known two approaches to the provision of drainage of wall systems:
- Surface trim drainage. for his device is necessary to make a preliminary site plan, including work on creating deviations from buildings, pits and trenches.Mounting surface drainage is carried away from the buildings.
- Deep trim drainage. In this case, using special tubes and materials that help equip the drainage in the immediate vicinity of the foundation walls of the building (on the perimeter).
trim Deep drainage
Today trim deep drainage foundation is considered the most effective.Its main function is to prevent the flooding of the basement of his home and basements.
Drainage system pipe layout is divided into the following types:
- Contour (to protect the foundation of the house);
- areal (protection areas);
- Single Line.
popularity is contour drainage .Pipes located at the perimeter of the protected structure, close enough to all the outer sides of the foundation of the house.In this drainage system consists of corrugated perforated pipes, special facilities for water discharge and drainage wells.Around the perforated pipe filter is created from gravel and sand.Stiffeners help to increase the safety margin in the cross section along the entire length of thin-walled tubes, allowing them remaining light, withstand decent load at a depth of up to 10m.Arrangement of drainage pipes should be made with a slight slope.
Modern drainage pipes are made of PVC with a diameter of 5 to 20 cm.Perforation drainage pipes does not allow penetration of the material used for dusting the drainage system.Hole area should not exceed 0.5% of the surface area of the tube.Thanks to a number of advantages that have appeared recently in the construction market of polymeric drainage pipes radically affected the drainage device.Plastic pipes are strong and light, flexible and at the same time tough.Lay the drainage system of PVC pipe can be to a depth of 8m.Because polymeric drainage pipe in the ground, are completely protected from sunlight, is significantly prolongs the use of polymeric drainage (over 50 years).
depth drainage device is determined by your requirements to reduce the level of groundwater, as well as the type and drainage system.It is often enough surface drainage, it is important only to choose the right waterproofing and correctly apply it.Waterproofing also used in caulking compounds and pipe joints and manholes.
for dusting drainage suitable granite rubble or gravel.
Appointment of drainage wells - is monitoring the correct operation of drainage and cleaning of drainage lines.
Drainage wells are prefabricated from plastic elements.Inside the well poured layers of gravel and sand or broken bricks, and formed a layer on top of the turf is laid, which is to prevent the filling from the formation of a layer of silt.According to the technology excess water discharged into the drainage well should go into the lower soil layers through the backfill or pumped for border area development drain pump.
Experts recommend at the same time to carry out drainage works installation of all kinds of utilities.
