Ang Mo Kio Ave 3, Singapore
To provide an extensive roof system to enable the establishment of an extensive green roof on the roof of the extension project of the French school of Singapore.
VersiDrain® 25P drainage and water retention trays were installed directly over the waterproofing membrane. Geotextile filter fabric was then laid over the VersiDrain® 25P trays and a planting media was spread on top for in-situ planting of selected plant species. Water retained by the water reservoirs of the trays during wet periods is returned to the planting media by capillary action during dry spells and drawn upon by the plants to sustain vigorous and healthy growth.
