Why do I need drainage?
I must say that this issue of concern to enough people who live in their suburban areas, especially if the site is located in a fairly deep depressions and sufficiently close ground water. If this problem does not pay any attention, you will soon land on which the house owner himself will become a swamp, which will be extremely difficult to put in normal form and drain. In the spring of land with houses will be constantly pouring spring water, which will soon lead to the destruction of the basement and reflected badly on the walls of the house.
To successfully avoid all these negative phenomena, it is important to do drainage at the site. Drainage consists of several perforated pipes, which are interconnected by drainage wells. To hole pipe is not clogged mud or debris, the filter materials sealed tube. Drainage pipes are laid on the perimeter of the house, around the perimeter, along the tracks and parking spaces. The pipes must be laid with a gradient towards the discharge of water. The diameter of the drain pipes is varied and yet, of course, will depend on the abundance of water in your country site and from the site area. Typically drainage pipe diameters - 160 mm.
The drainage system can be open or closed. Of course, it is preferable not to have his dacha closed drainage type to him especially, no one paid attention. Subsurface drainage on your property realistically and qualitatively different from the open drain. When the device of the drainage system closed type, it will be necessary to dig a ditch, fill them with gravel and sand. After laying there culverts, you fall asleep again these pipes with gravel, and the top cover all the turf.
And the last. Before starting work on the laying of the drainage system, you definitely need to determine the water discharge point. Shoot all the heights on leveled and calculate the slopes of drainage pipes, and the height of the drainage wells. Otherwise all these your work will not bring you any positive results.
