VersiDrain® 25P water retention & drainage sheet by Elmich Australia![]() VersiDrain 25P is a lightweight, high strength perforated sheet that both stores and drains water on green roofs. VersiDrain 25P sheets when covered with geotextile and soil media allow water and soluble nutrients to become stored in an array of mini reservoirs or cells and returned to the soil, via capillary action. Versidrain 25P cells are interconnected by channels that allow water to flow between the reservoirs. Perforations in the channels allow excess water to flow to outlets ensuring fail-safe drainage. Versidrain 25P protects waterproofing membranes and the high compressive strength effectively supports the weight of growing media and even large trees. Advantages
