Diffusible protective and drainage membrane with water storage function. 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 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. Then the required fill (plant substrate, chippings, gravel, crushed stone, etc.) is applied to a filter-stable geotextile laid separately on DELTA®-FLORAXX. Even in the inverted roof, greening, the creation of terrace areas or simple gravel is possible without any problems.
DELTA®-FLORAXX 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. This is followed by a filter-stable geotextile on which the plant substrate is applied in the next step. The planting is then done individually.
