Delta Membranes Systems - DELTA® Terraxx – Green roofs

DELTA Terraxx is a dimpled sheet with a geotextile layer which acts as a surface layer. Usually used as a green roof external drainage layer which also protects the primary waterproofing applied to substrate prior. Laminated on to the dimpled sheet, a layer of compression-resistant permanent filtration geotextile prevents the dimple structure from being clogged up by sludge, thus guaranteeing optimum drainage in the long run. Terraxx is an external membrane that can be used vertically and horizontally. The membrane has an adhesive tape manufactured on one side to overlap and join to the next part of membrane.

Terraxx is ideal for when you are extending a basement into your garden. Click the technical drawing to the right to show a typical basement garden extension where the Terraxx is being used to protect the basement from above. See how it is linked with our other waterproofing products, Koster 21 or Deuxan 2c to achieve a continuous waterproofing system.

For vertical application we supply all the necessary fixings and capping strips. Geo-drain clips to curtain hang membrane and MS profile to cap the top off. When using insulation behind the Terraxx you can use our Schraube fixings and Terraxx profile capping strip.
