Product Description

Its dimpled sheet provides outstanding drainage and physical protection over under-ground foundation walls. The nonwoven geotextile mat over the dimples creates a continuous air gap for reliable ventilation and drainage of water inflow from the surrounding soil. This composite system excels in a wide variety of other application sectors as well, including basements, underground parking grages, roof terraces, parking garage roofs, etc, providing users a variety of benefits.
