J-Drain 150 48"x50'

Performs a multi-faceted role by providing protection for waterproofing systems and managing sub-surface water around
building foundations. Consists of a light duty impermeable low profile polymeric sheet cuspated under heat and pressure to form a high flow dimpled drainage core. The core is then bonded layer of nonwoven filter fabric. The filter fabric retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass into the drainage core. Collected water is then conveyed to a proper collection system.
