River wash gravel is placed in the drain trench to aide in water flow. Then we put in Polydrain, an air-gap technology drainage board in the cove area in which the base wall meets the cellar floor. This heavy duty constructed drainage matting is bent and placed the wall up and above the trench. It raises water and directs intruding water because of hydrostatic pressure to the subgrade tile system. After the installation of this Polydrain that the trench is sealed with commercial grade concrete.
Interior Basement Waterproofing solutions can also include wall systems. Options are a 6 mil polyethylene vapor barrier that’s tucked in the Polydrain and installed normally from floor to ceiling. It’s easy to wash, 100% waterproof and does not support mold, mould or bacteria growth. For wall regions with higher water content, such as corners, problem areas or older structure, Polydrain can be installed full wall or chest elevated.
