River wash gravel is put in the drain line trench to aide in water flow. We then put in Polydrain, an air-gap tech drainage board in the cove area where 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 raises water drainage and directs intruding water due to hydrostatic pressure into the subgrade tile system. After the installation of the Polydrain the trench is sealed with industrial 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 typically from floor to ceiling. It’s easy to clean, 100% waterproof and does not support mold, mould or bacteria growth. For wall regions with high water content, like corners, problem areas or older construction, Polydrain can be installed complete wall or chest high.
