Gardens by the Bay consists of three distinct waterfront gardens – Bay South, Bay East and Bay Central, set in the heart of Singapore’s new downtown Marina Bay, adjacent to the Marina Reservoir.
Spanning 101 hectares, Gardens by the Bay is an integral part of a strategic plan to transform Singapore from a ‘Garden City’ to a ‘City in a Garden’. The aim is to raise the quality of life by enhancing greenery and flora in the city. The Gardens have been designed with the environment in mind, adopting environmentally sustainable technologies and is intended to be a statement in sustainable engineering and energy efficiency.
VersiCell^® modules were installed at the base of the planter boxes above the underground car park to provide sub-surface drainage. The fully mature luscious trees and shrubs form a green horse-shoe shaped curtain surrounding the central coach and bus parking area above the underground car park.
The Flower Dome is the larger of the two conservatories at the Gardens, at 1.2 hectares. It replicates cool dry conditions and features permanent displays of plants found in the Mediterranean and semi-arid tropical regions. There is also a display field to enable flower shows and non-permanent displays to be exhibited within the Conservatory.
VersiWeb^® slope stabilisation webs installed over the perimeter slopes of the Flower Dome serve as slope stabilisers and also provide media containment to make planting on the steep slopes possible.

Fushionopolis Walk, SIngapore

To provide the Landscape Roof system for planting the perimeter landscaped ramp, sky terraces and rooftop of the building to create recreational space and also offer protection for the waterproofing membrane and assist in the collection of rainwater for recycling.

About 10,000 sq m of VersiCell^® drainage modules placed directly over the waterproofing membrane of the planted areas, provide the drainage cavity beneath a geotextile filter fabric layer and the planting soil above. It prevents the roof from becoming waterlogged and ponding after heavy rain. The drainage modules also provide a protection for the waterproofing membrane, prolonging its serviceable life.
The sum of the vegetated areas of this building exceeds the footprint of the site on which it sits. The uninterrupted 1.5 kilometer long spiral ramp, with a minimum width of 3 m, runs from ground level all the way up to the rooftop, expanding into spacious sky terraces as it rounds each corner of the building. These skyrise green spaces create areas for relaxation and event spaces and allow occupants of the building to interact with and experience nature.
Water discharging from the sub-surface drainage modules is channeled to drainage downpipes at the perimeter ramp and also the roof via siphonic drainage and stored in tanks. A storage capacity of over 700 m3 allows for over five days of irrigation of the building’s extensive landscaped areas via recycled water between rainfalls
