Application

When designing a roof with high load traffic, the primary aim is to ensure the effective and fast drainage of water. DiaMassive-25 conducts the water permeating the layer structure through the lower drainage opening to the lower level of the drainage board where it can flow freely to the roof outlet.

Specification

Drainage board with CE marking, made of polystyrene, formed on both sides, high load capacity, for green roofs with pedestrian and vehicle traffic. Tested according to EN ISO 256192, EN ISO 12958 and EN 12225. Made of recycled polystryrene; Compressive strength (unfilled): 827.9kN/m2; Compressive strength (filled): 1214.4kN/m2. Water flow capacity at 2% tested according EN ISO 12958 – 0.68 l/(m×s); In-fill volume: 11.8 l/m2; Weight: about 2,0 kg/m2; Board size: 196×90×2.5 cm (l×w×h), laying with overlap.
