Studded drainage membrane DiaDrain-60H

polystyrenedrainagewater storage

Advantages • High rain- and irrigation-water retention → approx. 30,5 l/m2 water storage capacity • Protecting the waterproofing against the scattering of the filling material → protective overlapping edge around the board • Increased contact surface → heightened protection of the waterproofing through the favorable weight distribution • Long-term ventillation of the root area → increased diffusion openings • Durable and high compressive strength material (HIPS) → no water cooling needed during summer installations • Preventing the sinking of the filter layer → dedicated support cones • Suitable for flooded blue roof → Flooding height with approx 50 mm; with the combination of DiaDrain- 60H-UP as a DiaDrain-120-WM wassermanagement system up to 100 mm water level • Fire classification regarding EN 13501-1 → classified as class „E" construction product, therefore without limitation applicable DIADEM® build-up • Vegetation • Growing media • VLF-200 filter layer • DiaDrain-60H drainage board (filled) • VLS-500 water retention and mechanical protection layer • Root resistant waterproofing membraine • Roof construction Application Rainwater-retention and flow-delay drainage board for semi-intensive or intesive roof gardens, for green roofs with flooded irrigation system and for paved roofs with sporadical traffic, eg. car parks, fire department access roads.
