ABSTRACT:
A water impervious, elastomeric coating is applied to the outer surface of a foundation wall and across the joint between the lower end of the wall and the footing. Protection board is bonded to the elastomeric coating and serves to prevent damage to the coating during backfilling of the foundation wall. The protection board is composed of an impact resistant, extruded, thermoplastic material and has inner and outer faces connected together by a series of parallel spaced ribs which define vertical channels that extend the height of the board. A plurality of spaced isolated holes are formed in the outer face of the board and communicate with the channels. The board not only protects the elastomeric coating from damage, but the inner face provides an additional waterproofing membrane, and the holes and channels facilitate movement of water to the drain tile and relieve hydrostatic pressure on the wall.
