To provide root-resistant waterproofing membrane
To provide the Landscape Roof system for intensive green roof installation on the rooftop of the multi-storey car park
Evalon PVC/EVA terpolymer root-resistant waterproofing membrane was used to protect the roof skin beneath the green roof.
Elmich Landscape Roof
About 15,000 sq m of VersiCell® sub-surface drainage modules were installed directly over the waterproofing membrane provided a void beneath the planting media to enable expeditious transport of excess water to drainage outlets on the intensive green roof. A non-woven geotextile filter fabric was placed over the drainage modules to allow a 100mm sand layer to be spread on top followed by the soil media for plants from shrubs to small trees to be planted. An automated irrigation system was also installed to deliver water and nutrients to the plants at regular intervals.
