River wash gravel is put in the drain line trench to aide in water stream. We then put in Polydrain, an air-gap tech drainage board at the cove area where the foundation wall meets the basement floor. This heavy duty built drainage matting is bent and put up the wall and above the trench. It raises water drainage and leads intruding water due to hydrostatic pressure into the subgrade tile system. Following the installation of the Polydrain the trench is sealed using commercial grade concrete.
Howard County Interior Basement Waterproofing solutions can also include wall systems. Alternatives are a 6 mil polyethylene vapor barrier that’s tucked in the Polydrain and installed typically from floor to ceiling. It is easy to wash, 100% waterproof and doesn’t support mold, mould or bacteria development. For wall areas with high water content, like corners, problem areas or old structure, Polydrain can be installed complete wall or chest elevated.
