ABSTRACT:
An insulative waterproof drainage material is presented. The insulative drainage system comprises, in part, a plastic sheet having a plurality of alternate valleys and raised portions in the sheet defining a core. Preferably, the core leads to a slotted pipe. The core has two opposing surfaces. One surface has a water previous fabric material attached thereto while the other surface has a layer of thermally insulative material, preferably a polymeric foam material thereon. The foam or other insulative material has a pre-selected thickness which provides a sufficient R (thermal) value. This insulative drainage system is formed into panels and then adhesively applied to the exterior of a foundation or other retaining wall using any suitable and well known adhesive. Preferably, each panel is provided with interlocking joints which permit a watertight fit between adjacent panels.
