GXP® DREN 5+5 is a combination of a membrane pressed from high density polyethylene (HDPE) with a welded polypropylene geotextile (ref. no. Typar®SF32-40). The geocomposite forms a space constituting a perfect drainage layer and the reserve of geotextile 5 cm over the membrane prevents penetration of the filling into the upper section of the system. A structure of double embossings enables a combination of ventilation functions with water drainage, that is, it ensures optimal ground drainage as well as control of moisture and aeration of the covered surfaces of foundation walls. GXP® DREN 5+5 is applied in civil engineering as well as for drainage of building constructions.
