Marina Bay Sands Waterfront Promenade – Singapore

To provide sub-surface drainage beneath deep planter trenches along the waterfront promenade.

VersiCell drainage modules were installed to provide a drainage cavity beneath the planting media in the deep planter trenches along the Waterfront Promenade. This facilitates the efficient drainage of excess subsoil water and prevents water-logging within the trenches which also serve to hide large pipes and services. The drainage modules also offer a protection layer above the waterproofing membrane, provided by a fully adhered layer of Avalon PVC/EVA terpolymer membrane.

15 Joan Road – Singapore

To provide the Green Roof system to facilitate planting on the existing metal roof tops of the main building as well as the adjacent buildings at this address.

Elmich Green Roof was chosen because it is light and easy to install.
VersiCell structural drainage/insulation cells were used to fill the space between the metal ridges of the metal roofs, providing a ventilation layer and also creating a level flat surface. A separation sheet and geotextile was laid on top followed by installation of VersiDrain 25P drainage and water retention trays.

A filter fabric is positioned over the trays and EnviroMix GR, a lightweight and primarily inorganic planting media, installed on top for the planting of selected drought-tolerant plants.
An automated irrigation system is incorporated on the roofs for use during the initial plant establishment and to deliver water in prolonged periods of drought.

W Residences @ Sentosa Cove – Singapore

To provide pedestal support for installation of pavers at rooftop Jacuzzi terraces.

VersiPave pedestals with extenders added to bring them to the appropriate required heights were installed to support pavers at the rooftop Jacuzzi terraces. VersiPave pedestals have four quadrants, each with individually adjustable chocks that keep paved surfaces level even when paver thickness are irregular. The raised pavers eliminate efflorescence, allow services to be conveniently hidden, as well as provide thermal and acoustic insulation. Unwanted water freely drains through the gaps between pavers enabling the paver surfaces to dry out quickly on the terraces.

HDB Car Park Roof @ 309B Ang Mo Kio Avenue 1 – Singapore

To provide the green roof system including the lightweight planting media to convert the roof of the existing car park into an accessible and aesthetically pleasing green amenity area.

The green roof uses VersiDrain 25P to provide water retention and drainage, and a geotextile filter fabric to retain the lightweight planting media.

VersiDrain 25P keeps the manicured lawn on the roof well irrigated and thriving during dry spells, through delivery of stored water via evaporation and capillary action. It also prevents water logging after heavy rain by facilitating drainage of excess water. The green roof also provides thermal insulation, reducing the transference of heat from the roof to the car park level immediately below. The trays also offer protection to the waterproofing membrane, a root-resistant fully adhered layer of Evalon PVC/EVA terpolymer membrane, prolonging its serviceable life.

The green roof enhances urban aesthetics as residents in the vicinity get to enjoy the view of a cool soothing green roof instead of an exposed hot concrete roof. Additionally, in a highly urbanised HDB estate, the green roof mitigates urban heat island effect to keep the surrounding ambient temperature down.

United World College of South East Asia – Singapore

To provide waterproofing membrane protection prior to casting and under-screed drainage to allow entrapped water in the screed to discharge at the sports courts of the college on the roof of the building housing the bus parking bays.

VersiDrain 6P sheets, installed prior to casting over the waterproofing membrane, offers immediate protection against inadvertent membrane penetration or damage due to installation of various services at the promenade. Waterproofing is provided by a fully adhered layer of Avalon PVC/EVA terpolymer membrane. VersiDrain 6P is covered with geotextile fabric followed by a reinforcing wire mesh on top.

The capillary break created by the sheets between structural slab and topping screed prevents water and salts in the screed from migrating upward and also releases hydro-static pressure by allowing the trapped water and dissolved salts to discharge, minimising efflorescence and possibility of cracking on the surface.

VivoCity – Singapore

To provide sub-surface drainage beneath planted areas and also waterproofing membrane protection on the roof.

VersiCell drainage modules were installed to provide the cavity beneath the landscape roof to facilitate efficient sub-surface drainage. An open surface design and high internal void enables VersiCell to rapidly capture and transport excess water preventing the planted areas from becoming waterlogged.

VersiCell modules interlock to form large panels ensuring that they stay securely in place, especially necessary for the larger areas. It also provides a protection layer for the waterproofing membrane, prolonging its serviceable life.
The landscape roof incorporating a tropical island resort-like feel with many coconut trees has played a pivotal role in helping VivoCity to win the inaugural SIA-NParks Skyrise Greenery Award.

HDB Car Park Roof @ 180 Edgefield Plains – Singapore

To provide sub-surface drainage beneath planted areas on the intensive green roof as well as protection for the waterproofing membrane.

VersiCell^® drainage modules were installed to provide a drainage cavity beneath the geotextile filter fabric layer and the planting soil above. Its open surface design and high internal void enables VersiCell^® to rapidly capture and transport excess water after heavy rains, preventing the roof from becoming waterlogged.

High compressive strength allows its use under the trafficable and the heavy load-bearing areas of the roof. Additionally, the modules also provide a protection layer for the waterproofing membrane, prolonging its serviceable life.
The landscape roof mitigates urban heat island effect by sheltering the car park roof from the sun, reducing surrounding ambient temperature. Transference of heat to the car park level immediately below is also consequently reduced. The landscaped roof installed, with numerous large and shady trees, resembles a wooded country garden. It is aesthetically pleasing and provides additional shaded amenity and recreational space for the residents in the vicinity to enjoy.
The landscape roof also offers environmental benefits by acting as an air and chemical filter. Stormwater runoff is filtered at source, prolonging its residence time, thus alleviating downstream flooding.

HDB Car Park Roof @ 88 Tanglin Halt Road – Singapore

To provide the intensive roof system to enable the establishment of a landscape roof on the roof of the car park.

VersiCell drainage modules provide a drainage cavity beneath the geotextile filter fabric layer and the planting soil above. An open surface design and high internal void enables VersiCell to rapidly capture and transport excess water, preventing water-logging. The high compressive strength of the modules allows its use under trafficable areas. The drainage modules also provide a protection layer for the waterproofing membrane, a root-resistant fully adhered layer of Evalon PVC/EVA terpolymer membrane, prolonging its serviceable life.
The landscape roof enhances urban aesthetics as residents in the vicinity as well as commuters from the neighbouring MRT Station get to enjoy the view of a cool soothing green roof instead of a dull exposed hot concrete roof. Additionally, the green roof mitigates urban heat island effect in the highly urbanised HDB estate to keep the surrounding ambient temperature down.
