Product Description

J Drain 400XL/420XL performs a multi-faceted role by providing protection for waterproofing systems and managing subsurface water around building foundations. Soil backfill is retained by a filter fabric while allowing water to pass into the drainage core providing hydrostatic relief. Designed for extra heavy-duty vertical and horizontal applications that demand greater compressive strength and improved filtration for challenging soil conditions.
