Lot One Shopping Mall – Singapore

To provide modular vertical greening system for 3 free-standing decorative green walls at the void deck of the shopping mall.

Free-standing metal frameworks were installed in troughs and anchoring pilasters installed on both sides of each framework. VGMs, pre-planted in a controlled nursery environment were mounted to both sides of each framework enabling the free-standing green walls to be viewed and enjoyed from either side. Elements of design were also incorporated requiring the sides of each green wall installation to be covered with steel cladding and the troughs covered with granite pavers to conceal the base of the support framework with the addition of a precision water-jet fountain in one of the troughs.

Pasir Ris Park, Singapore

To provide slope stabilisation for plant media confinement and sub-surface drainage and water retention to enable planting on the RC pitch roofs of the activity shed cum shelter and toilets at the entrance to the Park.

VersiDrain 25P^® drainage and water retention trays were installed directly onto the RC roof tops and a geotextile filter fabric positioned over the trays. In addition to functioning as a sub-surface drainage, the network of cells in VersiDrain 25P® trays retain water which is returned, via capillary action, to the planting media during dry periods, helping to maintain and sustain healthy plants.

VersiWeb^® cellular confinement panels were then placed over the geotextile fabric within the raised curb borders of the roofs and the expandable cells filled with EnviroMix^® GR, a lightweight inorganic planting media. The honeycombed cells of VersiWeb® contain and confine the planting media on which locally-sourced drought tolerant plants requiring minimal maintenance were planted. VersiWeb^® uniformly distributes weight-bearing loads and prevents planting media and plants from being dislodged and sliding down the sloping roofs.

The green roofs blend into the green ambience of the Park and also help to keep the interior and activity spaces beneath them cool.

Aramsa Garden Spa – Bishan Park, Singapore

To facilitate planting on top of existing metal Corus Kalzip roof to provide an attractive green roof that will assimilate well into the natural ambience of the Park, serve as thermal insulation and also help to reduce noise transference during heavy rainfall.

To prevent plant media movement, aluminium battens were anchored onto the metal sloping roof and VersiCell drainage modules were placed between the metal ribs to provide an insulating barrier and a level surface for the subsequent installation of VersiDrain 25P drainage and water retention trays. A geotextile filter fabric was then positioned over the drainage and retention trays and EnviroMix GR lightweight inorganic planting media placed over the filter fabric. Locally sourced plant species selected for their hardiness, colour, height and ability to tolerate high tropical rainfall followed by hot and dry periods and requiring minimal maintenance were planted.

HortPark – Singapore

To provide a modular vertical greening system to enable planting of a wall specifically erected for demonstration and display of various green wall systems at the HortPark.

Steel anchoring pilasters were installed on the full face of the wall with careful attention to alignment. VGMs holding primarily soil-less lightweight planting media contained in a geotextile bag were pre-planted in a nursery environment. Front and rear metal support frames are added to the VGMs on site to provide reinforcement and facilitate anchorage onto the pilasters. A drip irrigation system delivers timed release of water and nutrients to the plants. VGMs can be individually dismounted from and re-mounted onto the pilasters to allow for easy maintenance or replacement if necessary.

Goodwood Residence Showflat – Singapore

To provide a modular vertical greening system to enable planting on both sides of a decorative free-standing wall at the entrance of the condominium.

A steel support frame was installed providing the centre skeleton and anchoring support. VGMs each containing a geotextile bag filled with specially mixed soil-less lightweight planting media and pre-planted in a nursery environment were mounted directly onto both sides of the centre anchoring support. Water and nutrients to sustain plant growth is supplied by a drip irrigation system.

Capella Hotel – Sentosa, Singapore

TO provide a modular vertical greening system to enable planting on 2 symmetrical walls of 250 m² each up to a height of 3 storeys.

VGMs, comprising a geotextile bag filled with lightweight planting media were pre-planted with Asplenium and various species of ferns in a nursery environment prior to installation. Encased in support frames on site, the VGMs were then mounted directly onto the slightly concave walls and a drip irrigation system installed to supply regular water and nutrients to the plants.

Private Residence at Merryn Road – Singapore

To provide both bearer and paver support beside the swimming pool.

VersiJack pedestals with bearer holders and spacer tabs were installed to support bearers and pavers respectively beside the swimming pool. The resultant paved area is a combination of wooden decking and pavers which creates a pleasant and attractive pool deck area. The raised pavers and decking hides services, facilitates efficient drainage of water from the surface and eliminates the possibility of efflorescence forming on the pavers.

Orchard Central Mall – Singapore

To provide paver support and conceal services and pump system for water fountain feature.

VersiJack high strength pedestals extended with 9 extenders to approximately 800 mm were positioned in a deep trough to support heavy pavers to create a void beneath with sufficient depth to conceal an elaborate pump system for a water fountain feature. Necessary adjustments for slope and height were made with the integrated slope corrector and screw and locking ring system in the pedestal respectively and minor height differentials corrected with rubber shims. The water fountain feature with programmed light and water display is now a point of focus on the ground floor of the shopping mall.

Bugis+, Singapore

To provide efficient drainage and void filler in deep planter boxes.

VersiTank were assembled and positioned over the waterproofing membrane in the deep planter boxes providing an insulation layer protecting the membrane. A geotextile filter fabric layer was then installed over the tanks and planting media placed in the planter boxes above the geotextile. VersiTank acts as a drainage cell with large internal void as well as a void filler to reduce the volume of planting media required to fill the deep planter boxes. VersiTank has high compressive strength and is able to resist the combine weight of the planting media and the large trees installed in the planter boxes.

California Pension Service (CalPERS) Building – Sacramento California USA

To provide efficient drainage under 10,000 m² of landscaped areas positioned over underground parking areas, to withstand the weight of onsite mechanical equipment, during the installation of soil mix and to bear the weight of large tree plantings.

VersiCell^® interlocking panels were positioned directly onto the waterproofing membrane, providing membrane protection and covered with geotextile. Planting media was positioned on the geotextile and turf and plant species installed.
VersiCell, unlike cuspated drainage sheets, when covered with a minimum 100mm of soil mix, withstands the weight of bobcats and other mechanical equipment during the installation of soil mix. VersiCell also resists the weight of large newly established and mature tree species. VersiCell is three times more efficient than dimpled drainage sheets in capturing and transporting sub-surface water and does not suffer from severe restriction, caused by geotextile sagging between dimples, in cuspated drainage sheets.
