Highly pressure-resistant protection and drainage system offering an extraordinary high-pressure resistance and an extremely robust filter fleece. Can be used on areas which may be driven on by trucks and on areas with high traffic volumes, as well as in vertical applications with installation depths of up to 20 m.
The material combination of pressure-resistant dimpled sheet and laminated, filter-stable geotextile serves as a drainage layer for all the types of DELTA® -TERRAXX by offering an effective protection to the pressure-resistant substrates from any mechanical influences. Furthermore, the strips are equipped with an integrated self-adhesive edge and have a tested long-term durability of 100 years.
The highly pressure-resistant protective and drainage sheet can be used as follows:
