Application
Rainwater retention and drainage plate extensive and semi-intensive green roofs and paved surfaces subject to vehicular traffic, made of recycled polystyrene with increased impact resistance (HIPS). The specially designed barrier structure provides a run-off retarding effect.
Specification
Heavy duty flow-delay drainage board of recycled high-impact polystyrene, 25 mm high, of paved/wooden surfaces of roof areas and for gravel roof build-up. Due to its excellent load bearing capacity it is appropriate for drainage layer under heavy vehicle roads. Compressive strength 1089,2 kN / m2 (unfilled), water flow capacity on 2% roof slope 0,57 l / m2s certified according to EN ISO 12958.
