River wash gravel is put in the drain line trench to aide in water flow. Then we install 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 put up the wall and over the trench. It raises water and leads intruding water due to hydrostatic pressure into the subgrade tile system. After the installation of the Polydrain that the trench is sealed using commercial grade concrete.
Arnold Interior Basement Waterproofing solutions may also include wall systems. Alternatives are a 6 mil polyethylene vapor barrier that’s tucked into the Polydrain and set up typically from floor to ceiling. It’s not difficult 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 old structure, Polydrain may be set up complete wall or chest high. Additionally, there are commercial grade epoxy and polymeric acrylic coatings available.
