River wash gravel is placed in the drain trench to aide in water stream. We then put in Polydrain, an air-gap tech drainage board at the cove area where the foundation wall meets the basement floor. This heavy duty built drainage matting is bent and placed the wall up and above the trench. It increases water and leads intruding water because of hydrostatic pressure to the subgrade tile system. After the installation of the Polydrain that the trench is sealed using industrial grade concrete.
Glen Arm Interior Basement Waterproofing solutions may also include wall systems. Options are a 6 mil polyethylene vapor barrier that’s tucked in the Polydrain and set up typically from floor to ceiling. It’s easy to clean, 100% waterproof and doesn’t support mold, mildew or bacteria development. For wall areas with high water content, such as corners, problem areas or old structure, Polydrain may be set up full wall or chest elevated. Additionally, there are commercial grade epoxy and polymeric acrylic coatings available.
