High-quality, CE-marked drainage system with a water reservoir for roofs with limited fall that are planted with extensive or intensive vegetation, or where extensive drainage lengths are required. The drainage system prevents the build-up of hydrostatic pressure on the waterproofing membrane, protects it against mechanical loads and ensures that vapour is able to evaporate freely from the XPS insulation on an inverted roof.
