Reliable geocomposite for protecting bituminal waterproofing

The GXP DREN F drainage geocomposite is a material made by extrusion of high-density polyethylene (HDPE), connected on both sides with DuPont™ Typar® thermally bonded polypropylene geotextile and a slip-on foil. It is intended for mechanical protection of thick-layer bituminous waterproofing and optimal drainage of foundation walls. Thanks to its properties, the GXP® DREN F geocomposite is also perfect for various applications in the field of civil engineering and for drainage of building structures, it has a high compressive strength of 250 kN/m², thanks to which it can protect pressure-sensitive waterproofing against damage.


  • 3-layer drainage and protection membrane
  • high compressive strength
  • protection of the waterproofing coating
  • ensuring optimal drainage surface
  • prevents damage resulting from ground movements, backfilling of excavations or subsidence of buildings
