The level of groundwater in the region is quite high, and you have to be prepared for the fact that even at the excavation may require pumping water. It is possible that the drainage will have to build up to the start of laying the foundation. The perfect solution — it draining area by drainage device before the construction of the house .
Drainage — a system of channels running on removal of excess moisture from the area. There are two basic types of drainage: superficial and deep. Drainage of surface water during heavy rainfall is done using open drainage — channel width up to half a meter and a depth of 80 centimeters — dug around the perimeter of the site. Them water from the site drains into the gutter. Sometimes for aesthetic or technical reasons, the use of open drainage undesirable ditch lined with geotextile, create a bed of gravel, put it in the drain pipe, covered with sand, impose top fertile soil and lay sod. This drainage and removes excess moisture from the soil depth, and rainfall. Recessed drainage — a complex engineering system, it is necessary to accurately calculate the diameter of the pipes and their inclination. Especially important is securely mounted around the pipe joint portion. Therefore, these works are best left to experienced professionals of the company «Stroy Garant».
Blind area and drainage around the basement
In addition to drainage around the perimeter, and using tape weakly deepened foundation around it does not hurt to build a blind area with a slope and a width of not less than one meter. And on the perimeter of the foundation to prepare for the depth of the drainage outlet water that will flow from the blind area. Otherwise, during the autumn rains or melting snow to flow under the house water vspuchit soil under the foundation. And, despite the overall drainage area, your home can «float».
In any case, you should not skimp on geological expertise areas — and the choice of foundation, it is desirable to entrust to specialists. Then you do not have to spend much more substantial sums for subsequent repairs or rebuilding.
