GrateTrench™

If you have a wet basement not only do you have to be concerned with water penetration under and through the basement walls but also from entrances. So how to we prevent water from flooding through the walkout basement doors, bilco doors, and garage doors? That’s easy, we rely on the industry leader and their engineered basement entrance drainage system … GrateTrench™.

GrateTrench™ prevents water from getting into your basement. The system relies on a drainage channel with a grated cover, typically installed above bulkheads, at the base of basement stairs and across exterior doorways. GrateTrench™ has a unique valve system that opens automatically to let water in and closes when water is not present. Only two teaspoons of water is needed to open the drain valve. A closed valve system will not allow odors from stagnant water to rise and permeate the home. GrateTrench™ closed valve system also minimizes entry of harmful radon gases. The GrateTrench™ system works in conjunction with the basement drainage system GrateDrain™(which we highly recommend) so you never have to worry about water or high humidity levels in your basement again.
