Drainage Mat for Eliminating Hydrostatic Pressure
Driwalltm Prefabricated Composite Drain 10/045-2 is a 0.40-inch, square grid geometric patterned core, drainage mat designed to eliminate hydrostatic pressure from behind foundation walls, retaining walls, planters and plaza decks, 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 protectionof the waterproof membrane from damage during back fill.
