279 Upper Serangoon Road, Singapore

To provide the drainage under-layer beneath the artificial turf of the sports field to be installed on the RC rooftop of the car park of the International School.

The RC surface of the car park rooftop was protected by a waterproofing membrane and then covered with a geotextile fabric. Following this, 6034 sq m of VersiCell^® sub-surface drainage cells were connected into a massive continuous mat over the geotextile to provide the base drainage layer beneath the artificial turf. A further geotextile layer was then laid to blanket the VersiCell^®, onto which the artificial turf panels were rolled out and installed and the necessary field markings created. A cushion of 25mm of sand and 15mm of Styrene-Butadiene Rubber (SBR) rubber were mechanically spread over and eased into the artificial turf to complete the installation.
VersiCell^® enables water permeating through the artificial turf and fine sand and SBR rubber layers to be transported expeditiously to drainage outlets at the perimeter of the field. This efficient discharge of water enables the field for various sports, including American Football and soccer, to dry out quickly after heavy rains.

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
Solaris was awarded the Green Mark Platinum rating, the highest level of certification granted by BCA’s Green Mark, Singapore’s sustainable building benchmark.

Hospital Drive, Singapore General Hospital

To provide support for installation of pavers
To provide sub-surface drainage modules to facilitate efficient drainage in planter boxes

VersiJack^®
VersiJack^® pedestals were extended to appropriate heights and positioned directly over the floor slab to support heavy 600 x 600 x 50mm pavers. A screw-adjust and an integrated locking ring system allowed easy height adjustments and confirmed heights to be secured. Slope Correctors allowed compensation for any slope to fall in the floor slab to facilitate drainage beneath the raised pavers whilst Spacer Tabs enabled constant gaps to be maintained between the pavers. Rubber shims were placed over the Spacer Tabs on the pedestal tops both to make minor height adjustments and provide insulation to reduce vibration and sound transfer. The raised pavers create attractive safe, dry and level open spaces and pathways at the hospital’s landscaped sky gardens.
VersiCell^®
VersiCell^® sub-surface drainage modules were installed at the base and also the sides of planter boxes at the sky gardens. Healthy plant growth is sustained by providing the necessary drainage to prevent waterlogging and ponding in the planter boxes. A geotextile was laid over the modules and 100mm of sand placed on top before infill of approved soil media for planting.
The planter boxes and paved open areas and pathways in the sky gardens create a greener and cooler new heart centre with a therapeutic environment.
