Prefabricated Drainage Composite
US 200DB consists of a high flow dimpled drainage core formed from a light duty impermeable polymeric sheet cuspated under heat and pressure then bonded to a layer of non-woven filter fabric. The filter fabric retains soil and sand particles or freshly placed concrete or grout, allowing filtered water to pass into the drainage core. Please limit to 20 feet of backfill.
US 220DB includes the addition of a protection sheet bonded to the back side of the core for soft membrane waterproofing systems. US 220DB is compatible with waterproofing systems without the use of a protection board. Please limit to 20 feet of backfill.
Collected water is then conveyed to the US SWD collection system.
