Abstract
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 spaced-apart protrusions and an outer waterproof membrane which covers recesses formed by the protrusions and provides a substantially smooth exterior surface.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
97 words
A foundation protection system, comprising: a foundation having an outer surface; a waterproof sheet having an inner surface facing the outer surface of the foundation and an outer surface opposite from the inner surface; the waterproof sheet having spaced-apart protrusions extending towards the outer surface of the foundation and providing drainage space extending from the foundation to the waterproof sheet; the protrusions forming recesses on the outer surface of the waterproof sheet; and an outer membrane on the outer surface of the waterproof sheet, the outer membrane covering the recesses and providing a substantially smooth exterior surface.
Claim 2
Dependent Claim
97 words
A foundation protection system, comprising: a foundation having an outer surface; a waterproof sheet having an inner surface facing the outer surface of the foundation and an outer surface opposite from the inner surface; the waterproof sheet having spaced-apart protrusions extending towards the outer surface of the foundation and providing drainage space extending from the foundation to the waterproof sheet; the protrusions forming recesses on the outer surface of the waterproof sheet; and an outer membrane on the outer surface of the waterproof sheet, the outer membrane covering the recesses and providing a substantially smooth exterior surface.
