WaterGuard is an interior waterproofing system that is more efficient and lasts much longer than other perimeter systems. Unlike other systems where it is placed alongside of the footing, WaterGuard is placed on top of the footing. This is important because now since it's on top, mud will not get in the drain and clog it simply because the drain is not sitting in the mud. After WaterGuard is completely installed, new cement will be laid over it to the point where you won't even know its there.
