To provide an extensive roof system to enable the establishment of an extensive green roof on the roof of the extension project of the French school of Singapore.

VersiDrain^® 25P drainage and water retention trays were installed directly over the waterproofing membrane. Geotextile filter fabric was then laid over the VersiDrain^® 25P trays and a planting media was spread on top for in-situ planting of selected plant species. Water retained by the water reservoirs of the trays during wet periods is returned to the planting media by capillary action during dry spells and drawn upon by the plants to sustain vigorous and healthy growth.

To provide the Green Roof System to enable planting on the roof of the house

The green roof system was placed on a structural concrete rooftop slab. VersiDrain® 25P, drainage and water retention trays, were installed on the roof and covered over with a geotextile fabric to enable a lightweight, nutrient rich formulated soil medium (by Code Green) with a maximum of 2.5 inch thick to be installed on the trays. The plants were propagated off site prior to the commencement of the construction allowing the plants to grow during this period. Various grasses, Sedums, Delospermas, and other succulents were hand planted on the roof, which is un-irrigated.

To provide pedestal support for installation of pavers at rooftop bar

VersiPave® supports the 600 mm x 600 mm pavers; eliminating the use of heavy bedding sand on the roof areas, facilitating rapid drainage of water from the paved areas. Each VersiPave® has individually adjustable integrated chocks which are used to ensure that paved surfaces are uniform and level. The air gap created beneath the pavers provide heat and sound insulation, hide miscellaneous services and also serves as a capillary break which prevents dissolved salts and minerals from migrating to the paver surface and form unsightly efflorescence.

To provide green wall system for installation of two green walls

VGP Mounting Panels were installed onto two walls to facilitate mounting of VGP Trays, from floor to ceiling, two-storey high, at the main entrance hallway of the school and on a lower wall fronting the school’s assembly area. The mounting panel at the bottom right was installed first followed by the other panels of the bottommost row systematically from right to left. Subsequent panel rows follow above in the same sequential order. An automated irrigation system, consisting of a network of tubing and a control panel, was installed to supply irrigation to the individual trays at programmed intervals for pre-set durations.
VGP Trays were planted in-situ with selected pre-grown plants and hung 12 trays to a panel to create a dense and lush wall of plants instantly. Anti-lift arms were inserted into individual trays to prevent inadvertent dislodgment of the VGP Trays from their mounting points. The drainage outlets of the bottommost row of trays were connected to a horizontal base tube to allow excess water to be discharged without wetting the immediate area beneath the green walls.
The lush eye-pleasing green walls become instant living educational tools. They enable students of the school to learn that, for a very small ground level footprint, green walls are able to provide many benefits. They contribute to environmental sustainability, enhance aesthetics, improve health and wellbeing by providing a source of stress relief and escape from the demands of urban living. In the specific context of the school, these green walls offer an environment conducive to learning.

VersiWall® GM
Twelve free-standing metal framework structures were erected for pilasters to be secured for VGM modules to be anchored such that vertical greenery is possible all around the framework. Pre-planting of the VGM Modules in a nursery environment allowed selected plants to establish and be appropriately orientated prior to installation, creating lush green walls almost instantly at the hospital project at time of installation.</p>
Both the pitch roof and its retaining wall at the edge were also greened with the VGM system. Anchoring pilasters were installed directly onto the pitch roof and the wall for pre-planted VGM Modules to securely anchor. The completed installation turned the pitch roof and wall from what would have been bare, ordinary and unattractive building features into eye-pleasing and therapeutic green roofs and vertical gardens.
A total of 1630 VGM modules were used for this construction.
The skyrise greenery reflects contemporary research that highlights the significant influence greenery and nature in the built environment has on health and wellbeing, especially beneficial in the setting of the children’s hospital.

VersiJack
11,000 VersiJack pedestals were installed to support expansive raised paver areas in the hospital grounds. Spacer Tabs and Slope Correctors used on the pedestals enabled consistent gaps between pavers to be maintained and allowed compensation for any slope to fall for drainage on the installation surfaces respectively.
Height extensions and minor adjustments were easily achieved by adding extenders and by screw adjustment of the pedestals, and desired heights locked down with the pedestals’ integrated locking rings. The void created beneath the paver platforms allowed miscellaneous services to be hidden.

The vertical greenery, sloping green roof and raised paver areas of the hospital form a protective and insulating shield that helps to cool the hospital building. Not only eye-pleasing, the vertical and rooftop greenery help to reduce the carbon footprint of the hospital, assist in at-source stormwater management, mitigate urban heat island effect, whilst at the same time also creating a therapeutic green and healing green environment for the patients and staff of the hospital and visitors to enjoy.

HortPark – Singapore

To provide green wall system to enable planting on a high free-standing concrete wall

40 VersiWall^® GP (VGP) Mounting Panels were installed onto the 20 sq m wall, 5 panels high and 8 panels wide, according to the pre-determined design. The Mounting Panels facilitate easy mounting of 480 VGP Trays. To enable the overlapping perimeter flanges of individual Mounting Panels to easily align and overlap, the mounting panel at the bottom right was installed first followed by the other panels of the bottommost row systematically from right to left. The same sequential order is maintained for the subsequent panel rows that follow above the initial row.

An automated irrigation system was incorporated. The system consists of a control panel, 4 sprinklers and a network of tubing that will deliver irrigation and nutrients to the plants in the individual trays on the wall at programmed intervals for pre-set durations with the aid of a control panel.

The wall is divided into two sections, the top with 4 panel rows and the bottom with a single panel row. Each section has a fiberglass collection tray positioned at the base (below the bottommost tray row) to collect and discharge excess irrigation water.

Short lengths of tubing were connected to the drainage outlets of the bottommost row of trays of each section of the wall. The ends of these tubes are directed to the collection trays so that excess water flows into the trays before final discharge. The collection trays are filled with pebbles to prevent breeding of mosquitoes if the trays should pond.

The VGP Trays were pre-planted in a nursery environment with the selected pre-grown epiphytes. The epiphytic plants include vines (Rhaphidophora tetrasperma and Monstera deliciosa); creepers (Hoya Carnosa Compacta, Hoya obovata, and Rhaphidophora korthalsii); orchids (Vanilla planifolia and Vanda Miss Joaquim); ferns (Nephrolepis Spp, Adiantum SPP (Maidenhair), Polypodium, and Davallia denticulata); and an epiphytic cactus (Epiphylum oxypetalum).

The planted VGP Trays were hung 12 trays to a panel, to instantly create a dense wall of epiphytic plants. To prevent inadvertent dislodgment of the VGP Trays from their mounting points, Anti-lift Arms were inserted into each individual tray on the wall.

To provide green wall system to install two living walls

A metal framework for welded mesh to be secured was positioned vertically for each of the green walls and a maintenance corridor created by positioning the framework a distance away from the actual wall. The welded mesh enables each VGP Tray to be firmly anchored using four of the tray’s six anchor hooks.

With the convenient maintenance corridor, tubing for the irrigation system are installed unobtrusively at the back of the wall. Incorporation of an automated irrigation system with an integrated control panel enables delivery of irrigation water and fertilizer to the plants of the green walls at pre-set times and programmed durations.

Simple transportation mesh racks on casters enable trays, pre-planted off-site with selected green wall plants, to be easily transported. At the installation site the trays are anchored, according to a pre-determined design, onto the welded mesh to create the living wall. Thereafter, insertion of Anti-Lift Arms locks individual VGP Trays securely to the mesh, preventing inadvertent dislodgement of the trays.

The two VGP green walls totaling 95 sq m installed on the walls at the building exterior and interior courtyard of the School stand in testimony as to how functional aesthetics and a solution to enhance environmental sustainability can both be achieved at the cost of only a low ground level footprint.

To provide green wall system for installation of green wall

Mounting of the VGP Trays was made quick and easy by installation of proprietary VGP Mounting Panels which allow close mounting of up to 12 VGP trays per panel. A network of irrigation tubing was installed to automatically deliver water and fertilizer to the plants on the green wall at pre-set times for pre-determined durations, ensuring their sustained growth.

The VGP Trays were planted in-situ with selected lush pre-grown plants and hung at the maximum 12 trays to a panel to achieve a full lush green wall in the spa instantly. Anti-lift arms were inserted into individual trays to prevent inadvertent dislodgment of the VGP Trays from their mounting points.

The VGP Green Wall stands two-storey tall on the wall of the courtyard at the centre of the spa, visibly conspicuous through open wooden louvered windows from 3 sides. The VGP Green Wall brings a sense of peace and tranquility of a garden into the spa, complementing the spa’s therapeutic and serene ambience, helping to relieve tired minds and bodies and soothing stresses.

To provide green wall system to install living walls in an office

The easy to install and significantly mess-free VGP Green Wall system is the ideal system for the installation of living walls in an office. Selected green wall plants were planted off-site into the VGP Trays. This then enabled the planted trays hung onto simple mesh racks to be easily transported to site, avoiding mess from media spills associated with in-situ planting on site.

The pre-planted trays were then mounted according to a pre-determined design and pattern onto VGP proprietary mounting panels installed from floor-to-ceiling at the reception and on three pillar columns, each on two sides, in the open-plan work area of the office.

In addition to firm anchorage with 3 pairs of hooks, Anti-Lift Arms inserted into the individual VGP Trays lock them securely to the mounting panels, effectively preventing inadvertent dislodgement of the trays. A drainage tube installed to connect the water discharge outlets of the bottommost row of trays channel excess water away, and keep the immediate area beneath the green walls dry.

The VGP Green Walls enliven the office environment and are a source of relaxation and stress relief, for the occupants as well as visiting guests, clients and customers.

To provide the pedestal system to support bearers for installation of wooden decking at landscaped courtyard.
To provide sub-surface drainage cells for drainage in planter boxes.

VersiJack®
VersiJack® pedestals were used to support bearers for installation of three raised wooden decked areas that complement water features at the landscaped courtyard of the building.
Bearers were secured with self-tapping screws to Bearer Holders on the pedestals to ensure that they do not shift and remained firmly in place during and after installation of the wooden decking. Where installation surface was sloped to fall for drainage, Slope Correctors were used to allow adjustments of up to 5% to maintain a level decking surface.
Essential services were hidden beneath the raised decking whilst gaps maintained between individual panels of the decking allowed surface water to drain away, both features combined provide safe enjoyment of the verdant area and water features at the courtyard.

VersiCell®
VersiCell® sub-surface drainage modules were used to line the base as well as the sides of planter boxes. A geotextile filter fabric was installed over the modules before 100mm layer of sand followed by the media for planting were put in to enable planting of plants ranging from ground cover plants and shrubs to trees. The drainage modules prevent waterlogging and ponding in the planter boxes and help to maintain robust healthy plant growth at the landscaped courtyard.
