Basement Waterproofing
Interior drainage, also known as a “French Drain” or “perimeter drainage”, is the key to keeping your basement dry. The drain pipes are installed below your floor, next to the footing, and are surrounded by gravel. When water levels rise and hydrostatic pressure starts to build, these drain pipes will collect water and direct it to the sump pump basin where it can be pumped out and away from your home.
THE PROCESS
The process for installing interior drainage starts with removing approximately 8-10” of the concrete floor along the basement perimeter. At West Michigan Waterproofing, we use an electric jackhammer outfitted with a HEPA dust collection system to break up the concrete.
If your basement has a block wall foundation, we’ll also drill “weep holes” in each of the block cores to allow them to drain into our trench and remain dry. Prior to cementing, we install a drainage matting against the wall to cover the weep holes. Drainage matting also acts as a proactive protection barrier in case of a future leaking foundation crack.
When that is complete, we remove the concrete and dig our trench. Once the trench is complete, we add gravel, 4” perforated drain pipe, and finish with a layer of cement.
LIFETIME WARRANTY
Interior drainage is backed by our simple, lifetime fully-transferable warranty. In fact, our warranty is written out directly to the home. Other companies may charge a yearly fee for their warranty as well as make you jump through hoops to transfer it when you go to sell your home. We would rather keep it simple. No worries about misplacing it either, as we always keep a copy on file.
