> J-DRain 700 Series: J-DRain 700, J-DRain 720
Performs a multi-faceted role by providing protection for waterproofing systems and collecting excess water in planters, roof top gardens, and other horizontal surfaces. Planting soil is retained while allowing water to pass into the drainage core. The collected water is then conveyed to a proper collection system.
J-DRain 700
Consists of a heavy-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 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 720
The identical properties as J-DRain 700 with the addition of a protection sheet bonded to the backside of the cuspated core providing protection for soft membrane waterproofing systems. J-Drain 720 is compatible with waterproofing without the use of a protection board.
