This flexible, lightweight sustainable product is ideal for subgrade irrigation water control. The drain pipe, also called drain tile is connected to a polyethylene sump basin that holds the groundwater collected and channeled to it by the ADS pipe. For extra protection you will find Zoeller backup pump choices that can be installed in the exact same basin either centrifugal, water-powered or battery backup.
River wash gravel is put in the drain trench to aide in water stream. We then put in Polydrain, an air-gap tech drainage board in the cove area in which the base wall meets the basement floor. This heavy duty built drainage matting is bent and put up the wall and above the trench. It increases water drainage and directs intruding water because of hydrostatic pressure into the subgrade tile system. Following the installation of this Polydrain the trench is sealed using industrial grade concrete.
Montgomery County Interior Basement Waterproofing solutions can also include wall systems. Alternatives are a 6 mil polyethylene vapor barrier which is tucked in the Polydrain and installed normally from floor to ceiling. For a cleaner look and for walls using a high moisture content Polywall, an extruded resin sheet can be installed. It is not difficult to clean, 100% waterproof and does not support mold, mildew or bacteria growth. For wall regions with high water content, like corners, problem areas or older construction, Polydrain can be installed full wall or chest elevated. There are also commercial grade epoxy and polymeric acrylic coatings available.
