VersiDrain 25P is an interlocking plastic water retention and drainage tray designed to store and drain water under intensive and extensive green roof systems.
VersiDrain 25P trays are positioned on the waterproofing membrane, covered with geotextile and growth media and plants then installed. Water and soluble nutrients, become stored in an array of mini reservoirs or cells and are returned to the soil, via capillary action, for plant uptake, when required
VersiDrain 25P trays incorporate interconnected channels that allow water to flow between the reservoirs. Perforations in the channels allow excess water to flow to drainage outlets.
VersiDrain 25P protects waterproofing membranes against damage and the high compressive strength effectively supports the weight of growing media, plant species and other weight bearing loads.
