River wash gravel is placed in the drain line trench to aide in water flow. Then we put in Polydrain, an air-gap technology drainage board at the cove place where the foundation wall meets the cellar floor. This heavy duty built drainage matting is bent and placed the wall up and above the trench. It increases water and directs intruding water due to hydrostatic pressure to the subgrade tile program. Following the installation of this Polydrain that the trench is sealed using industrial grade concrete.
Interior Basement Waterproofing solutions can also include wall systems. Options are a 6 mil polyethylene vapor barrier which is tucked in the Polydrain and set up normally from floor to ceiling. It’s not difficult to clean, 100% waterproof and doesn’t support mold, mould or bacteria growth. For wall regions with high water content, such as corners, problem areas or old structure, Polydrain can be set up full wall or chest elevated.
