Windi Drain
System for roof gardens and green roofs
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.
WINDIDRAIN® may also be installed to create green areas where it was not previously possible. Plants and flowers, can easily grow on existing roofs, terraces and paved yards. The system, has a wide range of uses: to change paved roofs into a garden plot with shrubs and trees; to create intensive or extensive green roofs and for sport fields.
