River wash gravel is put in the drain trench to aide in water stream. Then we install Polydrain, an air-gap tech drainage board in the cove place in which the base wall meets the cellar floor. This heavy duty built drainage matting is bent and put the wall up and over the trench. It increases water drainage and directs intruding water because of hydrostatic pressure into the subgrade tile program. Following the installation of the Polydrain the trench is sealed using industrial grade concrete
Interior Basement Waterproofing solutions can also include wall systems. Alternatives are a 6 mil polyethylene vapor barrier that’s tucked into the Polydrain and installed normally from floor to ceiling. For a cleaner appearance and for walls using a high moisture content Polywall, an extruded resin sheet can be installed. It is easy to clean, 100% waterproof and does not support mold, mould or bacteria growth. For wall areas with high water content, like corners, problem areas or older structure, Polydrain can be installed full wall or chest elevated. There are also commercial grade epoxy and polymeric acrylic coatings available.
