River wash gravel is put in the drain trench to aide in water stream. Then we put in Polydrain, an air-gap technology drainage board in the cove area where the foundation wall meets the basement floor. This heavy duty built drainage matting is bent and put the wall up and above the trench. It increases water and directs intruding water because of hydrostatic pressure into the subgrade tile system. After the installation of this Polydrain that the trench is sealed with commercial grade concrete.
Chantilly Interior Basement Waterproofing solutions can also include wall systems. Options are a 6 mil polyethylene vapor barrier which is tucked into the Polydrain and set up typically from floor to ceiling. It’s easy to wash, 100% waterproof and doesn’t support mold, mould or bacteria development. For wall regions with high water content, such as corners, problem areas or old construction, Polydrain can be set up complete wall or chest elevated.
