ABSTRACT:
A system for forming a water tight spaced cavity adjacent a basement wall sitting on a footer adjacent the footer drain to prevent water leakage into the basement which incorporates a light weight material with suitable strength to form a water tight sealed open spaced cavity adjacent the wall and the footer drain extending from the footer to near the surface of the ground adjacent the wall so as to keep the outer surface of the wall dry. Preferably a polystyrene or a light weight material is utilized with ribbed or other internal structural supports made to support the outer skin of the unit away from the wall to create the open spaced cavity adjacent the wall.
