J-DRain 200/220

J-DRain 200 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.

J-DRain 220 includes the addition of a protection sheet bonded to the back side of the core for soft membrane waterproofing systems. J-DRain 220 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 J-DRain SWD collection system
