Studded drainage membrane DiaDrain-40H

polystyrenedrainagegreen roof drainage

Advantages • High rainwater retention → nearly 19,59 l/m 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 DIADEM® build-up • Vegetation (Intensive) • Growing media • VLF-150/200 filter layer • DiaDrain-40H| • VLU-300/VLS-500 mechanical protection layer • Root-resistant waterproofing membrane • Roof construction Application 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.
