A water impervious panel assembly for a foundation wall. A series of rigid, extruded thermoplastic panels are mounted in side-by-side relation to the outer surface of the foundation wall. Each panel has inner and outer faces connected together by a series of parallel spaced ribs which define vertical flow channels that extend the height of the panel. A plurality of holes are formed in the outer face of each panel and communicate with the channels. The holes and channels facilitate movement of water to the drain tile at the footing of the wall and relieve hydrostatic pressure on the wall. To provide a watertight vertical joint between adjacent panels, the inner face of each panel adjacent one vertical side edge is provided with a first vertical slot that communicates with the flow channel located adjacent that side edge and the outer face of each panel adjacent the opposite side edge is provided with a second vertical slot that communicates with a flow channel adjacent that side edge. A first vertical rib located outwardly of the first slot of one panel is received within a second slot adjacent the second side edge of an adjacent panel to provide an interlocking watertight joint between the panels.
A water impervious panel assembly for a foundation wall, comprising a first panel and a second panel, each panel having a first face and a second face disposed parallel to said first face, each panel also including a plurality of spaced parallel ribs connecting the faces together and defining a plurality of parallel flow channels, each panel having a first side edge and a second side edge, said ribs being parallel to said side edges, the first face of each panel having a first slot adjacent and parallel to said first edge and communicating with a first flow channel disposed adjacent said first edge, said first slot extending the entire height of said panel, the second face of each panel having a second slot disposed adjacent and parallel to said second edge, said second slot communicating with a second flow channel adjacent said second edge, said second slot extending the entire height of said panel, a first rib of the first panel bordering said first edge being disposed in the second slot of said second panel to provide a sealed joint between the first edge of the first panel and the second edge of the second panel, and a plurality of spaced openings in said second face of each panel and communicating with the flow channels.
A foundation construction, comprising a foundation wall having an inner surface and an outer surface, a plurality of panels disposed in side-by-side relation against the outer surface of said foundation wall and composed of rigid plastic material, and securing means for securing the panels to the outer surface of said foundation wall, each panel having an inner face disposed adjacent the outer surface of the foundation wall and having a parallel outer face, each panel also having a plurality of spaced parallel ribs connecting the faces together and defining a plurality of generally vertical flow channels, each panel having a first vertical side edge and a second vertical side edge and having a top edge and a bottom edge, said ribs being generally parallel to said side edges, the inner face of each panel having a first slot adjacent and parallel to said first side edge and communicating with a first flow channel adjacent said first side edge, said first slot extending the entire height of the panel, the second face of each panel having a second slot adjacent and parallel to said second side edge and communicating with a second flow channel adjacent said second side edge, said second slot extending the entire height of the panel, a first rib of a first panel bordering said first side edge being disposed in the second slot of a second panel to provide a sealed joint between the first side edge of said first panel and the second side edge of the second panel, and a plurality of openings in said second face of each panel communicating with said flow channels.
