Diffusion-open protective and drainage membrane with water storage function and equipped with an integrated, filter-stable geotextile. Surface drainage and water storage in one. Ideally suited for use on green as well as on inverted roofs.
The dimpled membrane is safe for drinking water, resistant to chemicals and does not rot in the ground.
DELTA®-FLORAXX TOP serves as a protective, drainage and water storage layer in extensive as well as intensively greened flat roof constructions. The dimpled sheet is rolled out on a protective fleece (min. 300g/sqm) above the root-proof seal with the dimpled side down. Since the filter-stable geotextile has already been integrated, the plant substrate can be applied directly to the product DELTA®-FLORAXX TOP during the next step. The planting is then done individually.
DELTA®-FLORAXX TOP is also used in the inverted roof as a diffusion-open cover for the thermal insulation. The dimpled sheet is laid on a water-draining separating layer with the knobs facing the roof insulation. After that, the required fill (plant substrate, chippings, gravel, crushed stone, etc.) will be applied directly to the DELTA®-FLORAXX TOP. Even in the inverted roof, greening, the creation of terrace areas or simple gravel is possible without any problems.
