J-DRAIN 400 Series performs a multi-faceted role by providing protection for waterproofing systems and managing sub- surface water around building foundations. Soil back fill is retained by a filter fabric while allowing water to pass into the drainage core providing hydrostatic relief. Collected water is then conveyed to a proper collection system. Consists of a impermeable polypropylene sheet cuspated under heat and pressure to form a high flow dimpled drainage core. The core is then bonded to a layer of nonwoven 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.

Applications:

• FOUNDATION WALLS
• RETAINING WALLS
• PLANTERS
• UNDER SLABS
• BRIDGE ABUTMENTS

J-Drain 400/420:

Maintains a very high flow rate while providing a higher compressive strength for greater depths. A very popular choice for vertical and horizontal single sided drainage applications. Moderate duty.

J-Drain 400XL/420XL:

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.

420 & 420 XL are identical to 400 & 400 XL with the addition of a membrane protective film on the back side.
