One of the most common drainage systems is the French drain, constructed by digging a few large, relatively shallow trenches to install a system of pipes in. These pipes are put around a building, directing the water flow away from the building and its landscaping. The pits must then be filled in with gravel.
While it is possible for some people to attempt this project on their own, I would recommend that you leave it to the professionals! Visit us to find out more about our services www.hornsbytarmacanddrainage.co.uk
