Universal protection and drainage system for green areas that can be walked on or driven on and for vertical applications with installation depths of up to 10 m.
Like all DELTA®-TERRAXX types, the material combination of pressure-resistant dimpled sheet and laminated, filter-stable geotextile serves as a drainage layer and effectively protects pressure-resistant substrates from mechanical influences. The strips have an integrated self-adhesive edge and a tested long-term durability of 100 years.
The universal protection and drainage sheet can be used:
The DELTA®-TERRAXX strips are available in a width of 75 cm for paths, bases, retaining walls and connections.
