Studded drainage membrane DIADRAIN-40H

polystyrenedrainagegreen roof drainage

High rainwater retention ⇒ nearly 19,59 l/m2 of water storage capacity Prevention of water channel system overuse ⇒ waterflow speed decreased by stepped barriers Microbiological resistance test (EN 12225) ⇒ additional protection for the waterproofing layer against microbiological damage Recessed evaporation vents ⇒ unobstructed aeration Durable and high impact-resistant material (HIPS) ⇒ stability under pavements, water cooling is not needed during summer installations Snap the board for the required size ⇒ No cutter needed on the work site Negligible overlap loss ⇒ economical installation and cost savings Increased contact area ⇒ decreased surface pressure Vegetation (Intensive) Growing media VLF-150/200 filter layer DiaDrain-40H VLU-300/VLS-500 mechanical protection layer Root-resistant waterproofing membrane Roof construction Water-retention and flow-delay drainage board for semi-intensive and intensive green roofs and hard-surface pedestrian areas for flat roofs and zero-degree slope roof construction, made of recycled high-impact polystyrene (HIPS). Suitable for solving standing water problems on existing roofs. Water-retention and flow-delay drainage board with CE marking, made of recycled high-impact polystyrene, 40 mm high, stepped barrier form, with recessed evaporation vents and water channel system on the underside, compressive strength unfilled: 338 kN/m2 according to test reports (average value measured by SKZ-Testing GmbH, Würzburg,Germany), compressive strength filled at 10% compressive strain: 588 kN/m2, the guarenteed minimum of the compressive strength: 210 kN/m2, water flow capacity on 2% roof slope 1,01 l/m×s certified according to EN ISO 12958,
