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.

VersiJack®
Over 10,000 VersiJack® pedestals support the bearers beneath wooden panels for the installation of extensive wooden decked areas at the 10th and 19th levels of the building. Slope Correctors were used to allow adjustments up to 5% to ensure that a level paver and decking surface is maintained throughout. The void under the raised decked areas allow essential services to be unobtrusively hidden and assist surface water to drain quickly away whilst at the same time reduce heat transfer from the decked surfaces to the roof.
VersiJack® pedestals also support pavers for the installation of a water feature at the Sommerset entrance to the premises. The gaps, created by using Spacer Tabs on the pedestals, between the pavers facilitate drainage of water from the pavers back into the water feature.

VersiCell®
VersiCell® sub-surface drainage modules totalling more than 1,000 sq m were installed directly over the Evalon® waterproofing membrane in the planter boxes of the E-Deck and sky terraces. They provide a void beneath planting media to enable expeditious transport of excess water to drainage outlets and prevent waterlogging. A non-woven geotextile filter fabric placed over the VersiCell® allowed a 100mm sand layer to be spread on top followed by the soil media for planting.
In the densely built environment of Orchard Road, the over 1,000 sq m of skyrise greenery form a living barrier that helps to shield and reduce heat absorption by the building. This lowers temperature within the building as well as the ambient temperature of the building’s immediate surroundings. In addition to subsequently reducing energy consumption for air-conditioning and helping to mitigate negative impact brought about by the heat island phenomenon, the skyrise greenery also performs a vital urban stormwater management role.

Evalon®
Waterproofing protection in the planter boxes was provided by nearly 6,000 sq m of a root-resistant fully adhered layer of Evalon® V PVC/EVA terpolymer membrane ideally suited for intensive and extensive green roof application.

To provide green wall system for installation of green wall at basement courtyard 

Proprietary Mounting Panels of the VersiWall® GP (VGP) 2060 green wall system were bolted directly to the wall to enable easy mounting of VGP Trays. The panels were installed from right to left starting from the bottom row in sequential order.

An automated irrigation system was installed to provide delivery of water and fertilizer at pre-determined times for pre-programmed durations.  The irrigation is divided into two zones.  The upper zone supplies irrigation from top of the wall to the halfway point on the wall and the other from halfway point to the bottommost row of trays of the wall. Excess water is discharged through the drainage outlets of the bottommost row of trays connected to a larger pipe laid below the wall. This keeps the immediate vicinity of the green wall dry.

VGP Trays were pre-planted off-site and delivered to site using transporting racks comprised of welded wire mesh tied to an A-frame.   The planted trays were anchored to the mounting panels from right to left starting from the bottom row, a sequence which allows easy close planting and is most systematic and efficient.  Plant palette provided by a selection of suitable plants created a pleasant design on the wall.  Anti-lift Arms were inserted to prevent inadvertent dislodgement of the trays from the wall.

Refreshing and eye-pleasing, the wall of living plants provides the elements of tranquility, peace and quiet, creating the quintessential ambience for respite and to unwind from events of the day when the occupants of the apartment return.

Turf Stabilisation
TurfPave® XD positioned onto compacted sand laid over the compacted substrate of the path created to provide fire engine access way. Infilled with a sandy soil mix TurfPave® XD provides a stable and firm substrate for turf establishment along the access way. When not in use as an access way for fire-fighting operations or emergency purposes, the access pathway remains green and aesthetically pleasing and can withstand constant daily pedestrian traffic.
Rainwater readily infiltrates into the compacted sand base below and then slowly into the substrate before eventual discharge into the local drainage system. An impermeable access way, like an asphalt road on the other hand, will not allow run-off to infiltrate and thus contribute to run-off volumes and stormwater management problems.

Landscape Roof / Sub-surface Drainage
VersiCell® sub-surface drainage modules were installed to line the interior of planter boxes, at the base and also the sides, to provide a void beneath planting media to enable expeditious transport of excess water to drainage outlets to prevent waterlogging. A non-woven geotextile filter fabric over the drainage modules form a filter separation layer that allowed a 100mm sand layer to be spread on top followed by the soil media. Plants from shrubs to trees create the lush landscaped gardens amidst abundant water features.

Extensive Green Roof
VersiDrain® 25P drainage and water retention trays were positioned on the RC rooftops of the clubhouse and two other buildings. A geotextile filter fabric laid over the trays enabled EnviroMix®, a primarily inorganic planting media, to be placed for planting of selected drought-tolerant plants that drape over the sides to form attractive skirts around the rooftops.

TurfPave®
TurfPave® XD is positioned onto compacted sand over a geotextile filter blanketing a sub-soil drainage base layer provided by VersiCell® placed directly over the constructed RC path. Infilled with a sandy soil mix the grass paver provides a firm substrate for turf establishment. The access ways created are green and aesthetically pleasing and provide a stable path for heavy fire engines and other emergency vehicles when needed. Rainwater infiltrates into the compacted base and is discharged via the drainage cell layer below, reducing excessive run-off and stormwater management problems which impermeable roads may pose.
VersiCell®
VersiCell® sub-surface drainage modules installed in planter boxes provide a void beneath the planting media to enable expeditious transport of excess water to drainage outlets for prevention of waterlogging. A non-woven geotextile filter fabric placed over the drainage modules allowed a 100mm sand layer to be spread on top followed by the soil media for plants from shrubs to small trees to be planted, and effectively turn the grounds of the condominium into landscaped gardens.

Turf Stabilisation
TurfPave® XD grass pavers were positioned onto a compacted sand base layer over the compacted substrate of the access way. Infilled with a sandy soil mix, TurfPave® XD whilst providing a stable and firm substrate for turf establishment also creates the mandated access way with ability to bear high compressive loads necessary for passage of fire engines and other emergency vehicles.
The TurfPave access pathway remains green and aesthetically pleasing and is able to withstand constant daily pedestrian traffic. TurfPave does not retain water and thus allows rainwater to infiltrate into the compacted sand base beneath and then slowly into the substrate throughout the length of the green passageway.
An impermeable asphalt road, if installed instead, would repel rather than temporarily retained the rainwater in the substrate and therefore subsequently contribute to excessive run-off and associated stormwater management problems.

Landscape Roof / Sub-surface drainage
VersiCell® sub-surface drainage modules were installed in planter boxes to provide a void beneath the planting media to enable expeditious transport of excess water to drainage outlets. A non-woven geotextile filter fabric placed over the drainage modules allowed a 100mm sand layer to be spread on top followed by the soil media. The resultant lush landscaped grounds, planted with plants from shrubs to small trees, are well-drained and have minimal water-logging problems.

Green Wall
VersiWall® GM (VGM®) vertically greens the retaining wall facing the lift shaft of a glass-walled elevator positioned to convey residents from the underground car park to surface level. VGM® Modules were pre-planted, 6 to 8 weeks prior to installation, with plants selected for ability to thrive in the narrow space in front of the lift shaft which is subject to strong light exposure at the top of the wall and subdued light at the bottom.

Nanjing, People’s Republic of China

To provide system to establish a 1200 sq m green wall along retaining wall

VersiWall® GM (VGM®) modules each contain a geotextile bag filled with a primarily inorganic soil-less lightweight planting media. Pre-planting of the modules 6 to 8 weeks prior to installation in a controlled nursery environment enabled selected green wall plants to be firmly established and orientated vertically. Pilaster mounting rails were bolted directly to the retaining wall to facilitate firm and secure anchorage of the VGM® modules to the wall. Attractive flowing living patterns were created by using the various shades of green, red and orange from the plant palette provided by the selected green wall plants. The otherwise featureless high wall is transformed into a majestic eye-pleasing living wall. The green wall extends a green welcome to commuters, athletes and visitors from around the globe arriving for the Summer Youth Olympic Games 2014 in Nanjing, People’s Republic of China the host city of the Games.
