A panel assembly for use as a combination drainage and insulation member, primarily on the exterior surface of subterranean walls. The assembly has an insulating board with channels on one side of the board. A fabric which is pervious to water and impervious to soil particles, and has a high modulus, is attached to the channeled side of the board. The resulting board is highly effective to collect water and channel it downwardly toward a drainage pipe which may be part of the drainage system, and which usually conveys the water away from the wall. Improved methods of providing subterranean insulation and drainage are also disclosed.

A panel assembly for collecting liquid and conducting it downwardly, said panel assembly comprising: (a) an insulation board having opposing outer surfaces, a top edge, a bottom edge, and two side edges, one of said outer surfaces having first channel means extending inwardly therefrom for conducting liquid toward said bottom of said board: and (b) a covering of a liquid pervious fabric having a high stress/strain modulus firmly attached to said board and extending over said one surface of said board, such that said fabric cannot be deformed by stretching to substantially intrude into said channels under normal earth loading conditions of typical subterranean foundations.
