Keene Building Products Driwall™ Prefabricated Composite Drain 10/025 - 48" x 100' Roll

DRAINAGE MAT FOR ELIMINATING HYDROSTATIC PRESSURE

The Driwall™ Prefabricated Composite Drain 10/025 is a 0.25-inch, zig-zag geometric patterned core drainage mat engineered to relieve hydrostatic pressure in demanding construction environments. Ideal for use behind foundation walls, retaining walls, planters, plaza decks, and balconies, this product eliminates the need for traditional aggregate drainage, saving time, labor, and space on the job site.

Crafted from an extruded polymer matrix of tangled monofilaments that are heat-welded at junctions, the core offers long-lasting resilience and strength. A non-woven geotextile filter fabric ensures soil or concrete stays clear of the drainage core, maintaining optimal performance over time.
