GXP® DREN

Home 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
