VersiDrain® 25P trays that enable water storage for reuse and free drainage of excess water were installed in the shallow planted areas. Geotextile was laid over the VersiDrain® 25P, followed by lightweight growing media and plants. Succulent sedum plantings add lush greenery to the cityscape.
VersiCell® lightweight drainage cells were installed at the base of deep planter boxes allow excess water to disperse.
VersiDrain® 8Geo, a dimpled drainage sheet with an adhered geotextile, was installed onto the planter box walls to protect the membrane and to promote drainage.
Pavers, supported on VersiPave® eliminated the use of bedding sand or screeds. This is a major benefit resulting in significant weight reduction on The Westbury’s building structure. The 4mm void created between each paver allows rapid water drainage onto the membrane and then to drainage outlets, ensuring that the levelled paved surface does not retain water. The waterproof membrane supplied by Green Roof Technologies, Evalon® is a sheet waterproofing membrane that is highly resistant to UV and plant roots, and is backed by a 20 year warranty.
