J-DRain 990

Prefabricated Drainage Composite

J-DRain 990 consists of a high flow dimpled drainage core formed from a light duty impermeable polypropylene sheet cuspated under heat and pressure then bonded to a layer of woven filter fabric. The filter fabric retains soil and sand particles or freshly placed concrete or grout, allowing filtered water to pass into the drainage core.

The drainage core is chemically resistant and designed for applications where chemical exposure is possible.
