GXP® DREN

Insulation and drainage membrane

The foil pressed from high density polyethylene (HDPE), combined with thermally welded polypropylene geotextile Typar® SF, is assigned for mechanical protection and optimal drainage of foundation walls. The geocomposite GXP® DREN is also perfectly fit for various applications in civil engineering (underground car parks, bridge abutments, terraces, foundations, retaining walls, etc.) as well as for drainage of building constructions.

Advantages

  • The combination of a bucket membrane with a geotextile provides an excellent drainage layer
  • The reserve of geotextile 5 cm over the membrane prevents penetration of the filling into the system and facilitates overlapping during a horizontal and vertical use
  • Possibility to produce rolls with the length of up to 35 m
  • A properly selected geotextile ensures optimal hydraulic capacity as well as optimal puncture resistance
  • The structure and the embossing densification ensures very good compression strength
