(57) ABSTRACT
A foundation protector for a foundation wall prevents moisture being retained in the foundation wall and also provides drainage for surface water so that water does not rest against the surface of the foundation wall. The foundation protector has a smooth exterior surface so that it remains attached to the foundation if earth subsidence occurs. The foundation protector includes a waterproof dimpled sheet with spacedapart protrusions and an outer waterproof membrane which covers recesses formed by the protrusions and provides a substantially smooth exterior surface.
