> J-DRain 302 > J-DRain 400 J-DRain 302 J-DRain 302 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 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 302 Consists of a heavy-duty, high-density polyethylene geonet drainage core with its ridges heat fused to a layer of non-woven filter fabric on the front and back sides providing drainage and filtration from both sides. 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.

Report No. ESR-1901		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.
