WINDIDRAIN® system to create roof gardens, provides superior water drainage, water storage, and aeration to create a harmonious balance of air and water in the substrate soil.
The WINDIDRAIN® elements are specifically designed for extensive and intensive roof gardens where substantial water retention is required for plant usage. They are light weight panels made of 100% recycled polypropylene, molded specially and designed with retention cups and drainage.
The unique design allows for the free drainage of excess water, achieving flow rates from 10 to 30 times higher than that of conventional drainage methods. At the same time, the system is engineered to promote irrigation through capillary action and evaporation into the soil/vegetation level. WINDIDRAIN® may easily be installed over waterproofing membranes or insulation. It is easily cut to fit around penetrations, perimeters, and drains. In applications where intensive green roof gardens are required, the retention cups may be filled with mineral substrates.
