J-Drain 400

J-Drain 400 is an impermeable polymeric sheet molded under heat and pressure to form a dimpled drainboard. This board serves to dissipate hydrostatic pressure by moving water away from the walls and foundation of a building to the base of its structure, where it is further drained by another system. The J-Drain 400 system is bonded to a nonwoven filter fabric, which separates sand and other debris particles from the water, and allows that water to safely flow out into another drainage system. J-Drain 400 is able to sustain a higher flow rate while providing a higher compressive strength for greater depths; making it suited for vertical and horizontal single-sided drainage applications. Best if paired with J-Drain SWD 6 or SWD 12 collection systems.
