River wash gravel is placed in the drain line trench to aide in water flow. Then we install Polydrain, an air-gap tech drainage board in the cove place in which the foundation 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 drainage and directs intruding water because of hydrostatic pressure to the subgrade tile program. Following the installation of this Polydrain the trench is sealed using commercial grade concrete.
Marriottsville Interior Basement Waterproofing solutions can also include things like wall systems. Options are a 6 mil polyethylene vapor barrier that’s tucked into the Polydrain and installed typically from floor to ceiling. It’s not difficult to wash, 100% waterproof and doesn’t support mold, mould or bacteria development. For wall areas with high water content, such as corners, problem areas or older structure, Polydrain can be installed complete wall or chest high. There are also commercial grade epoxy and polymeric acrylic coatings accessible.
