Drainage Mat for Eliminating Hydrostatic Pressure

Driwalltm Prefabricated Composite Drain 10/022 is a nominal 0.3-inch, “zig-zag” geometric patterned core, drainage mat designed to eliminate hydrostatic pressure from behind foundation walls, retaining walls, planters, plaza decks, and balconies.

The product is produced from an extruded polymer matrix of tangled monofilaments, which are heat-welded at the junctions to form a resilient structure. This product utilizes a non-woven geotextile filter fabric to hold the soil or concrete away from the wall or deck and the core.

When using Driwall Prefabricated Composite Drain, aggregate for drainage can be eliminated from a construction site.
