Very durable membrane

The GXP® Plus 20 membrane produced from high density polyethylene (HDPE), with the basis weight of 800 – 1200 g/m² , is assigned for green roofs, as well as mechanical and hydraulic protection of tunnels or other underground constructions with an increased water flow.


  • Very resistant to compression and puncture owing to buckets in the shape of a truncated cone
  • Enables uniform distribution of loads owing to high densification of buckets (400 items/m²)
  • Increased air space between embossings improves thermal insulation
  • During horizontal installation, limits capillary water rising, directs and removes water from downpipes (of the collector)
