DELTA FLORAXX TOP green roof membrane

Water-retaining drainage sheet with an integrated geotextile for perfect green roofs. Roll size 10m x 2m, fleece width 2.10m Innovative octagonal dimples for outstanding compressive strength. One sheet for drainage, water storage, and filtration. Easy and quick to lay out straight from the roll DELTA®-FLORAXX TOP in warm roofs with an extensive/intensive green cover. Developed specifically for use in green roofs, DELTA®-FLORAXX TOP, an innovative dimpled sheet, forms a protection and drainage layer with a high load-bearing capacity which is optimised for the requirements of horizontal drainage. Acting as a protection, filtration, and seepage layer, it retains 7L of water per m² within its thickness of 20mm. Thanks to its robust octagonal dimples additionally reinforced by ribs, the sheet will safely support even heavy loads. As the filtration layer is fused to the top of the sheet and does not need to be laid our separately, the substrate for planting may be spread directly on the sheet that prevents water from accumulating.
