River wash gravel is placed in the drain line trench to aide in water stream. We then install Polydrain, an air-gap tech drainage board in the cove area in which the base wall meets the cellar floor. This heavy duty built drainage matting is bent and placed up the wall and over the trench. It increases water and directs intruding water due to hydrostatic pressure to the subgrade tile system. Following the installation of the Polydrain that the trench is sealed using commercial grade concrete.
Interior Basement Waterproofing solutions may also include wall systems. Options are a 6 mil polyethylene vapor barrier which is tucked into the Polydrain and installed normally from floor to ceiling. It’s not difficult to clean, 100% waterproof and does not support mold, mould or bacteria development. For wall regions with high water content, such as corners, problem areas or old construction, Polydrain may be installed full wall or chest high. Additionally, there are commercial grade epoxy and polymeric acrylic coatings available.
