With access to the wall, a trench is created on the perimeter of the basement floor, with the concrete slab and subsoil excavated. The trench is created for the installation of Water Guard XL drainage system, which is designed to direct any water collected to the sump pump. It is covered with gravel and a replacement concrete slab. Unlike conventional French drains that are installed outside the foundation or alongside the footing, WaterGuard Drainage System is installed inside the basement and will not clog with silt or plant roots. It will capture any wall or floor seepage before it reaches the basement floor and damages the homeowner's belongings.
