J-DRain 200 Consists of a light-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. Limited to 20 feet of backfill. J-DRain 220 The identical properties as J-DRain 200 with the addition of a protection sheet bonded to the back side of the cuspated core providing protection for soft membrane waterproofing systems. J-DRain 220 is compatible with waterproofing systems without the use of a protection board. Limited to 20 feet of backfill. 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. J-DRain 400XL Designed for extra heavy duty vertical and horizontal applications that demand greater compressive strength and improved filtration for challenging soil conditions. Heavier duty drain core & fabric. J-DRain 420XL The identical properties as J-Drain 420 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. ---------------------------------------------------------------------------------------------------------------------------------------------------------- J-DRain 500 Consists of a perforated polymeric sheet cuspated under heat and pressure to form a high-flow dimpled drainage core. The core is then punched to allow double sided drainage, 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 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.   J-DRain 780 Consists of a heavy duty impermeable polymeric cuspated sheet (identical properties of J-DRain 700 core)bonded to a layer of heavy duty non-woven filter fabric (8 oz/sq yd.) J-DRain 990 Consists of a heavy duty impermeable polypropylene sheet cuspated under heat and pressure to form a high flow dimpled drainage core. The drainage core is chemically resistant and designed for applications where chemical exposure is possible. 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 Thin Drain A .125", 3-dimensional drainage core with filter fabric. It is designed to create an air void for ventilation while allowing water and moisture to pass through the drain core for easy removal.  Used primarily in under tile drainage. ----------------------------------------------------------------------------------------------------------------------------------------------------------- J-DRain SWD A modular composite drainage and collection system consisting of a 3-dimensional, high-flow, drainage core which is wrapped with a non-woven filter fabric. Available in 6,12,18, 24, & 36” widths.    J-DRain GRS A high strength pre-assembled drainage composite consisting of a dimpled core and two layers of geosynthetic fabric attached top and bottom. The dimpled core has water retention chambers for storing water while allowing excess water to pass through “perforations”. (1 in. dimple height). J-DRain GRS50 A high strength pre-assembled drainage composite consisting of a perforated, dimpled core and two layers of geosynthetic fabric attached top and bottom. The dimpled core has water retention chambers for storing water while allowing excess water to pass through “perforations”.  Similiar to GRS, except GRS50 has a smaller profile height (.40 in.). J-DRain 400RB Consists of a 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 root resistant filter fabric. J-Drain Turfcore Consists of a heavy duty polymeric sheet cuspated under heat and pressure to form a high compression, high flow dimpled drainage core. The core is then cut into speerate sheets to allow for expansion and contraction and then bonded to a layer of root resistant filter fabric.  Designed to enhance G-Max performance for synthetic athletic fields More information on J-DRain Products: Binders & Brochures Installation Instructions & Details Product Data Sheets & Specifications
