A green roof system of Elmich Australia installed at Universal Studios’ theme park in Singapore provides a barrier against tropical temperatures, helping to cool building interiors and the surrounding areas.

The total green roof area measures 35,000m² and VersiCell drainage cells were used to in-fill the space between the metal ridges to create a level surface on metal roofs sections. A separation sheet, geotextile and VersiDrain 25P drainage and water retention trays were also installed.

EnviroMix, a primarily inorganic soil-less lightweight planting media was then laid down and drought tolerant plant species that require little or no irrigation and maintenance were selected for the green roof system. Evalon, an EVA/PVC root resistant sheet waterproofing membrane was fully adhered to all concrete roof sections.
