Drainage Mat for Eliminating Hydrostatic Pressure

Driwalltm Prefabricated Composite Drain 10/022-2 is a 0.30-inch, “zig-zag” geometric patterned core, drainage mat designed to eliminate hydrostatic pressure from behind foundation walls, retaining walls, planters, plaza decks and balconies, while providing a protection fabric for the waterproof membrane.

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 structure utilizes a filter fabric to hold the soil away from the wall and core. A fabric is heat-laminated to the surface on one side so that in one step, aggregate for drainage can be eliminated from a construction site.

On the other side of the drain’s three-dimensional core, a protection fabric is heat-laminated. This fabric will act as a protection course to even the way the drain contacts the membrane on the foundation and in one step, provide drainage and protection of the waterproof membrane from damage during back fill.
