J-DRain 300, J-DRain 1000

J-DRain 300 and J-DRain 1000 consists of an HDPE geonet drainage core with a filter fabric bonded to one or both sides. The geonet drainage core is literally crush proof, yet flexible enough to conform to irregular surfaces. Because of their crush proof nature, geonet drainage composites can be used in the most extreme cases with heavy loads and /or heavy vehicular traffic.

J-DRain 400 Series: J-DRain 400, J-DRain 420

Performs a multi-faceted role by providing protection for waterproofing systems and managing sub-surface water around building foundations. Soil backfill is retained while allowing water to pass into the drainage system providing hydrostatic relief. Collected water is then conveyed to a proper collection system.


J-DRain 300
Consists of a heavy-duty, high-density polyethylene geonet drainage core with its ridges heat fused to a layer of non-woven filter fabric. The filter fabric retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass through to the drainage core. J-DRain 300 provides drainage from one side only.

J-DRain 1000
Identical to J-DRain 300 in physical properties with the addition of a layer of coated fabric bonded to the back side providing protection for waterproofing systems requiring a protection layer.

J-DRain 400
Consists of a moderate-duty impermeable polymeric sheet cuspated under heat and pressure to form a high-flow dimpled drainage core. The core is then bonded to a layer of non-woven 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. 

J-DRain 420
The identical properties as J-DRain 400 with the addition of a protection sheet bonded to the backside of the cuspated core providing protection for soft membrane waterproofing systems. J-DRain 420 is compatible with waterproofing systems without the use of a protection board.
