WINDIDRAIN vegetated covers for flat and slightly sloping roofs

WindiDrain elements provide for the drainage of excess water and retention of useful water.
Furthermore, they enable an excellent ventilation so as to create a harmonious balance between air and water in the substrate soil.
WindiDrain consists in lightweight recycled plastic panels, moulded specially and designed with water retention cups and drainage holes.

This unique design enables the free drainage of excess water and, at the same time, irrigation through the capillary flow and evaporation of water to the soil/vegetation level.
Since moisture retention cups have a significant load-bearing capacity, it is possible to place a soil substrate layer of considerable thickness over WindiDrain elements.
