intervention into the circulatory system of underground water level causes an increase of which, in turn, reduces the soil resistance, it leads to blistering and seasonal subsidence.Of course, it gives us great inconvenience and reduces the life of the foundation.

drainage under the foundation avoids the destructive action of groundwater and prevents flooding of basements, cracks in the foundation and walls of the building, skewed windows and doorways, and possibly the destruction of the building.At the same time it manages to get rid of excessive dampness of the walls and ceilings, from destruction of building structures by fungal diseases.

Drainage foundation with his own hands - where to start?

Make drainage strip foundation - not an easy task, but it is quite feasible.Of course, the drainage system equipment would be more reasonable to provide for even the design of the house, but if this was not done, the error must be corrected today.

trench must be excavated with a slope of 1 cm vertically on each longitudinal meter. slope directed toward the drain.The trench bottom is laid a layer of sand 5 cm, and on top of the sand is lined with a geotextile and its edges fixed to the walls of the trench.Following on top of the geotextile - another layer of sand, but this time see 10

thick layer of sand on the upper stacked perforated drainage pipe, and the pipe is filled gravel layer of 10 cm mounted on a wall of the trench geotextile edges are brought together and stitched...

At the end of the pipe, which should be located at a minimum distance of five meters from the house, water intake is arranged.Its upper part is to be a meter below the end of the pipe, but higher groundwater.In the simplest version of the receiving water is a plastic container with holes drilled in it, which is buried in a pit lined with geotextile.

Now that we know how to make the drainage of the foundation, find out where to place the manholes are designed to clean the drain pipes.As a rule, they are located at the corners of the building.If drainage trench extends along the long wall, the wells are arranged at a distance of 12-15 m apart.
