Aramsa Garden Spa – Bishan Park, Singapore
To create an extensive green roof on a sloped metal roof that will assimilate well into the natural ambience of the Park, serve as thermal insulation barrier and minimize noise transference during periods of heavy rainfall.
Aluminium battens were anchored onto the metal sloping roof to prevent plant media movement and VersiCell drainage modules placed between the metal ribs to provide a level surface for the subsequent installation of VersiDrain 25P drainage and water retention trays. A geotextile filter fabric was positioned over the VersiDrain 25P drainage and retention trays and EnviroMix GR lightweight inorganic planting media placed on the filter fabric. Locally sourced low maintenance plant species selected for their hardiness, colour, height and ability to tolerate high tropical rainfall followed by hot and dry periods were planted.
