Advantages
- Walkable-area compliance
With a total height of about 16 mm, it meets the drainage mat requirements of the ZVDH planning guide and the Gebäudehülle Schweiz leaflet for walkable areas over waterproofing.
- Very high drainage capacity
The optimised dimple structure and height drain more than some thicker products, even in heavy rain.
- Easy handling
At 1.04 m wide it is easy to transport, cut and align, especially in tight spaces such as balconies and loggias.
- Overlap design
A row of smaller dimples on one long side interlocks with the sheet below. A fleece overlap keeps grit and sand out of the drainage layer.
- Long-term durability
Tested ageing resistance supports a predicted service life of up to 100 years. Contains no recycled material.
- Sustainability
QNG-ready, free from ingredients subject to mandatory labelling, conforms to the EU taxonomy.
- Clog prevention
The laminated geotextile's 130 μm opening size stops the dimples clogging.
- Standards compliance
CE-marked to EN 13252, meets DIN 4095, DIN 18531 and DIN 18533.
Where to Use
Best for roof terraces, loggias and balconies in front of level thresholds, and special constructions such as zero-fall green roofs. Also standard uses: flat roofs with heavy gravel protection, under extensive and intensive green roofs, and under areas walked on or driven on by cars.
