GREEN ROOFS

DIMPLED MEMBRANE DRENAXX 20 GTX

• Quick and easy to lay from a roll

• Ideal as a green roof substrate

• Notched HDPE dimpled membrane with integrated PP geotextile

• The isolating and filtering geotextile prevents fine floating particles from settling within the drainage layer

• Increased resistance to pressure thanks to innovative octagonal profiles

• Quick drainage of excess water into water drains

• It does not decompose

Parameters

Grammage (g/m2) 1000
Width (m) 2
Length (m) 10
Dimple height (mm) 20
Compressive strength (kN/m2) 180
Capacity (l/m2) 7
Non-woven geotextile fabric (g/m2) 110

Application

  • Hydro-accumulative layer designed for use on flat and sloping green roofs
  • It retains water necessary for plants to survive during drought
  • Geocomposite acts as drainage and water storage
  • Geotextile performs filtration by allowing a fixed amount of water to be drained from the substrate layer and prevents the dimples from getting silted
  • It forms a protective and drainage layer with high resistance to loads while protecting the surface from freezing

Benefits

Waterproof

Durable

Broad scope of temperatures

Quality Warranty

Recycling

Conformity with standards

Reasonable price

ASSEMBLY

The DRENAXX GTX dimpled membrane in the construction of green roofs is laid on a layer of absorbent-protective non-woven fabric. The cusps should face down (the membrane must not be laid with the notches down) and an overlap of two rows of cusps should be created.
