New Insulation and drainage membrane

GXP® Dren 1200 Duo is a waterproof membrane extruded from high density polyethylene (HDPE), 1,2 mm thick, thermally joined with polyethylene geotextile made from continuous fibres 140 g/m² on the top side and polypropylene or polyester geotextile 250 gm² on the bottom side.

Used as:

  • An insulation and drainage layer for retaining and foundation walls, bridge abutments, waste dumps, ash collection tanks, floor slabs, tunnels, draining channels, green roofs
  • A separation and drainage shield in road, railway and airport foundation constructions
  • An increased friction angle between the base and the geocomposite prevents skidding of the geocomposite from slopes under the pressure of the ground


  • A layer protecting against mechanical damage of insulation layers
  • A draining layer for high loads
  • An anti-root layer
  • A sealing and degassing layer for:
    • rubbish dumps
    • waste collection sites
    • industrial tanks
