River wash gravel is put in the drain trench to aide in water flow. Then we put in Polydrain, an air-gap tech drainage board in the cove area in which the foundation wall meets the cellar floor. This heavy duty constructed drainage matting is bent and put the wall up and above the trench. It raises water and directs intruding water due to hydrostatic pressure to the subgrade tile system. After the installation of the Polydrain the trench is sealed with commercial grade concrete.
Cockeysville Interior Basement Waterproofing solutions may also include things like wall systems. Alternatives are a 6 mil polyethylene vapor barrier that’s tucked in the Polydrain and set up typically from floor to ceiling. For a cleaner appearance and for walls with a high moisture content Polywall, an extruded resin sheet could be set up. It’s not difficult to wash, 100% waterproof and doesn’t support mold, mould or bacteria development. For wall areas with high water content, like corners, problem areas or older structure, Polydrain may be set up complete wall or chest high. There are also commercial grade epoxy and polymeric acrylic coatings accessible.
