River wash gravel is put in the drain line trench to aide in water flow. Then we put in Polydrain, an air-gap tech drainage board at the cove place in which the base wall meets the cellar floor. This heavy duty built drainage matting is bent and put up the wall and over the trench. It raises water and directs intruding water due to hydrostatic pressure to the subgrade tile system. After the installation of the Polydrain that the trench is sealed using commercial grade concrete.

Ellicott City Interior Basement Waterproofing solutions may also include things like wall systems. Alternatives are a 6 mil polyethylene vapor barrier that’s tucked into the Polydrain and set up normally from floor to ceiling. It’s easy to wash, 100% waterproof and does not support mold, mildew or bacteria development. For wall areas with higher water content, like 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 available.
