J�DRAIN 300, 302, and 1000 are HDPE geonet drainage cores with a filter fabric glued to one or both sides
The geonet drainage core is nearly crush resistant while being flexible enough to adjust to uneven surfaces. Geonet drainage composites can be employed in the most extreme instances with heavy loads and/or significant vehicular traffic because of their crush resistant character. Physically identical as J�DRAIN 300, with the addition of a layer of heavy-duty gray cloth glued to the rear side to provide protection and cushion for waterproofing systems that require a protective layer. It provides drainage from one side only.
