River wash gravel is placed in the drain trench to aide in water stream. We then put in Polydrain, an air-gap technology drainage board at the cove area where the foundation wall meets the basement floor. This heavy duty constructed drainage matting is bent and placed the wall up and above the trench. It raises water drainage and directs intruding water because of hydrostatic pressure to the subgrade tile system. After the installation of this Polydrain that the trench is sealed with industrial grade concrete.
Butler Interior Basement Waterproofing solutions can also include things like wall systems. Alternatives are a 6 mil polyethylene vapor barrier that’s tucked in the Polydrain and set up normally from floor to ceiling. To get a cleaner look and for walls with a high moisture content Polywall, an extruded resin sheet could be set up. It’s not difficult to clean, 100% waterproof and doesn’t support mold, mildew or bacteria growth. For wall areas with higher water content, like corners, problem areas or older construction, Polydrain can be set up full wall or chest high.
