J-DRain Composite Drains

US Fabrics is proud to offer the J-DRain line of composite drains. These pre-fabricated composite drains, sometimes refered to as dimpleboards, strip drains or sheet drains, are an excellent alternative to traditional aggregate and geotextile wrapped pipe systems.

J-DRain prefabricated drainage systems (PDS) consist of two parts: a geosynthetic filter fabric and a molded plastic core. Geotextile fabrics have outstanding water flow. The fabric is attached to the core, providing excellent drainage while preventing the backfill from entering the core channel. The core is made of high strength plastic that withstands the type of abuse incurred during backfilling. Compared to traditional systems, J-DRains cost less, install faster and work better!

The high strength core in J-DRain Sheet Drains protects waterproofing and damproofing from damage during backfilling and freeze/thaw cycles.

J-DRain Sheet Drains rapdily lower hydrostatic head pressure by quickly transporting the water away from the wall down to the collection system at the base of the wall. The filter fabric prevents clogging by inhibiting migration of the soil fines, but allows water to enter the spacing in the dimpled core. The result is a highly effective and efficient drainage system.

J-DRain Sheet Drains are manufactured in lightweight, easy to handle rolls and eliminate the need for heavy equipment.

J DRain Sheet Drains offer predictable performance, providing excellent flow rates with most soil types and are tested per ASTM standards.

J-DRain SWD (site water drainage) strip drains offer superior drainage to traditional pipe and stone foundation & french drain systems and eliminate the concerns about gravel quality and soil fines. J-DRain pre-fabricated drains have an 80% open area compared to the 1%-3% open area for 4" perforated pipe and have a planar flow capacity in excess of 30 gal./min./lin. ft.

J-Drains lower installation costs. They install 50% faster than traditional systems, decrease the amount of soils remooved from the jobsite and eliminate the hassle of scheduling and waiting for delivery of gravel.

The felixible, lightweight rolls are easy to install, offer customized fitting and eliminate the need for heavy equipment.

J-DRain SWD drains high compressive strength (8,500 - 11,000 psf) and customized fitting ensure solid connections, long-term effectiveness and reliability.

J-DRain strip drains are ICC & NES approved nationwide for residential foundations (#NER-636).

J DRain Geonets consist of an extruded high-density polyethylene drainage core with a nonwoven filter fabric bonded to the ridges of the core.

The filter fabric retains soil or sand particles as well as freshly placed concrete or grout, allowing the filtered water to pass into the form

J-DRain Geonets are crush resistant (40,000 psf) and can be used in the most extreme environments, and with heavy loading, both horizontally and vertically.

J-DRain offers a full array of fittings and end caps to allow fast and easy installation. Ask your US Fabrics representative for further information.
