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 at the cove place where the foundation wall meets the basement floor. This heavy duty constructed drainage matting is bent and put up the wall and above the trench. It increases water drainage and directs intruding water because of hydrostatic pressure into the subgrade tile program. After the installation of this Polydrain the trench is sealed with commercial grade concrete.
Reston Interior Basement Waterproofing solutions may also include wall systems. Options are a 6 mil polyethylene vapor barrier that’s tucked into the Polydrain and set up normally from floor to ceiling. It is not difficult to clean, 100% waterproof and doesn’t support mold, mould or bacteria growth. For wall areas with higher water content, such as corners, problem areas or older structure, Polydrain may be set up complete wall or chest elevated. Additionally, there are commercial grade epoxy and polymeric acrylic coatings accessible.
