Amdrain is a two-in-one rigid Expanded Polystyrene (EPS) insulation board with integrated drainage channels. The panel is designed to be used in both exterior and interior applications for below grade foundation walls. The inner side (in contact with foundation wall) has vertical grooves (9/16”/14.2mm deep) creating small air gaps and allowing for moisture drainage while the opposite side is flat.
Amdrain EPS panel comes in 4’x8’ (1.22m x 2.44m) sheets with the thickness ranging from 1.5” (38mm) to 5” (127mm). The panels are designed to be installed in the vertical orientation only. The tongue and groove interlock helps maintain the continuity of the insulation eliminating the need for taping of the joints.
