    Water storage membrane DELTA®-FLORAXX

    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 material
    In comparison with the standard knobs, the octagon knob structure has greater compressive strength, while the perforation holes serve to allow diffusion and drain excess rainwater onto the sealing layer.

    Advantages

    • Large water reservoir of approximately 7 l/sqm
      DELTA®-FLORAXX stores rainwater. This is why it serves as a water reservoir for dry periods. Excess rainwater can run off through the perforation holes punched in the dimpled sheet and can be drained on the roof waterproofing between the knobs.
    • 80% higher compressive strength
      Thanks to the octagon knob with reinforcing ribs, it has an approx. 80% higher compressive strength than standard nubs.
    • Vapour-permeable
      Thanks to its perforation, the dimpled membrane is open to diffusion (with an SD value of approximately 0.4 m) by enabling unhindered drainage as well as vapour pressure relief. This prevents a closed water film from forming on the insulation and damaging it.
    • Logistics
      DELTA®-FLORAXX FLAT is also available in the format 2.35 x 1.00 m as sheet goods. 200 pieces and/or 470 sqm per industrial pallet. (Compare DELTA®-FLORAXX: 240sqm (6 rolls) on an industrial pallet)

    Application

    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.
