Singapore

To provide the Modular Green Wall system for the installation of a 85 m² Green Wall on the 35.4 m long wave-like RC wall fronting the main lobby of the Hotel, as part of its major upgrading and renovations.

The modular Elmich VGM Green Wall system was installed on the RC wall erected along the driveway fronting the main lobby of the Hotel. The 2.4m high wall serves to conceal the driveway leading to the Hotel’s underground car park on the other side of the wall. To account for the wall’s slightly meandering design, pilasters were spaced accordingly to allow mounting of the modular VGM modules along the wave-like curves of the 35.4m long wall. As the curves are very gentle, the slightly wider gaps between vertical rows of modules along the convex portions of the wall do not pose a problem as they are soon covered up when the plants are established.

The refreshing living wall serves as a welcome and invitation to guests of the Hotel from all over the world to discover the hotel’s new and exciting facilities after its extensive makeover.

University Town, National University of Singapore

To provide both intensive and extensive roof systems to enable the establishment of an accessible landscape roof at the lower deck and an inaccessible extensive green roof at the upper deck on the roof of the Education Resource Centre of University Town.

 Landscape Roof, Sub-surface Drainage
VersiCell^® drainage modules were installed directly on the waterproofing membrane to provide a drainage cavity beneath a geotextile filter fabric layer and the planting soil above. VersiCell^® with high internal void and an open surface design is able to rapidly capture and transport excess water, preventing the green areas on the roof from becoming waterlogged. The drainage modules also provide a protection layer for the waterproofing membrane, prolonging its serviceable life.
Extensive Green Roof
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 lightweight inorganic planting media, EnviroMix^® GR, spread on top for in-situ planting of various selected drought-tolerant plant species arranged in attractive patterns. 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
From their windows, students residing in the nearby Graduate Residences enjoy a refreshing, cool and aesthetically pleasing layered green roof instead of otherwise bare concrete roofs.

National University Health System, Singapore

To provide the Green Wall System to enable planting on the wall at consecutive levels, from the 2nd storey up to the 4th storey, at the centre atrium of the multi-storey car park of the tower block.

A steel framework was erected incorporating a “swing-door” system that allows pairs of adjacent vertical panels of VGM^® Planting modules to open/swing inwards. This enables accessibility to the living wall from the narrow corridor behind it, eliminating the need for erection of scaffolding to enable access to the face of the high 5-storey wall whenever maintenance is required. The ability of the panels to swing like a door, not only offers enhanced safety but is also cost effective for the long term maintenance of the high living wall.

Each VGM^® Planting Module contains a geotextile bag filled with soil-less lightweight planting media. Modules were pre-planted in a nursery environment 3 months prior to installation for firm establishment and vertical orientation of the selected green wall plants to take place. On site, each module was reinforced with steel brackets and the corners bolted directly to the framework. An irrigation system was incorporated with its piping configured to allow the swing action of the hinged panels.

The mural-like living wall, “painting” the consecutive walls from the 2nd storey to the 5th storey of the car park, presents a pleasing and therapeutic welcome for patients and visitors to the building.

Sentosa, Singapore

To provide slope stabilisation for plant media confinement to enable planting on the mushroom-shaped roof over the gymnasium and also on the steep slope of another roof of the seafront condominium.

VersiDrain^® 25P water retention and drainage trays, facilitating water retention and serving as a base drainage layer, were installed and blanketed over with a layer of geotextile fabric. VersiWeb^® panels were then installed with anchoring to the roof facilitated by strong metal rods embedded in the concrete. The honeycombed cells of VersiWeb^® contain and confine the planting media on which a carpet of Sedum is planted. VersiWeb^® uniformly distributes weight-bearing loads and prevents planting media and plants from being dislodged and sliding down the sloping roofs. Perforations in the VersiWeb^® cell walls facilitate inter-cell drainage, preventing hydrostatic build-up.

The resultant green roofs are not only aesthetically pleasing but are also an effective shield against harmful UV rays from the intense tropical sun. The crown of vegetation protects and prolongs the lifespan of the waterproofing membranes on the roofs and also keeps the interior living spaces beneath them cool and comfortable.

Cove Drive, Sentosa – Singapore

To provide slope stabilisation for plant media confinement to enable planting on the pitched and horizontal rooftop of the seaside bungalow.

Water retention and a base drainage layer is provided by VersiDrain^® 25P water retention and drainage trays. A geotextile filter fabric is then installed blanketing the water retention and drainage trays.

For added security and strength, VersiWeb^® panels are installed straddling the horizontal rooftop and the steep slope of the concrete roof to be planted. The honeycombed cells of VersiWeb^® contain and confine the planting media for the establishment of a refreshing crown of grass. VersiWeb^® uniformly distributes weight-bearing loads and prevents planting media and the carpet of grass from being dislodged and sliding down the steep sloping roof. Perforations in the cell walls of VersiWeb^® facilitate inter-cell drainage and prevent hydrostatic build-up.

Besides setting the bungalow apart from its immediate neighbours, the resultant green slopes are aesthetically pleasing and form an effective shield against the intense tropical sun, helping to protect and prolong lifespan of the waterproofing on the roof. The green roof also helps to keep interior living spaces cool and surrounding ambient temperatures down, mitigating UHIE.

Rasa Sentosa Resort, Singapore

To provide a modular green wall system to enable vertical greening, both along the front pavement corridor and at the lobby of the beachfront resort hotel.

A stainless steel framework is constructed to enable the green wall at the lobby to tower beyond the height of the wall beside the staircase spiraling from the basement to the lobby at ground level. To allow adequate time for plant establishment, Vertical Greening Modules (VGMs), comprising a geotextile bag filled with soil-less lightweight planting media were pre-planted in a nursery environment about 8 to 12 weeks prior to installation. Metal support brackets are attached to the VGMs on-site enabling the them to be easily and firmly anchored to pilasters secured to the steel framework or directly to the wall. The Elmich modular green wall system allows easy mounting and dismounting of individual VGMs for maintenance or replacement whenever necessary.

Automated drip irrigation and fertilisation systems were installed for each of the walls.

The inviting living wall at the front corridor greet guests and visitors as they arrive at the resort and the towering green wall at the lobby sets the mood for a refreshing stay at Singapore’s only beachfront resort.

Marina Bay Financial Centre, SIngapore

To provide strong and secure paver support to support heavy pre-cast concrete sections weighing up to 5 tonnes to be raised 900 mm off the base structure.

 Elmich Green Wall System, consisting of Vertical Greening Modules (VGMs) housing a geotextile bag containing soil-less lightweight planting media was specified for this project. Pre-planting of the VGMs was carried out at the nursery about 8 to 12 weeks before scheduled installation, allowing firm establishment and gradual vertical pre-orientation of specially selected indoor plants. On site, metal support brackets were attached to the modules to facilitate their mounting onto pilasters fastened to a steel framework.

A drip irrigation system is incorporated in the system and a drainage gully installed at the base of each wall to collect and channel excess water. Excess water is drained via a down pipe with connection to and linking the drainage gullies of all 8 levels.

Artificial lighting is provided above the walls to provide the plants with an adequate source of light to maintain healthy plant growth.

Jurong Central Park

To provide the Green Roof system to facilitate planting on the mushroom-shaped concrete pitch roof of the McDonald’s restaurant at Jurong Central Park.

The steep gradient of the mushroom-shaped roof necessitated metal restraining barriers to be installed before VersiDrain^® 25P drainage and water retention trays, cut to fit the individual compartments created by the restrainers, were positioned. A filter fabric is laid over the trays and a lightweight and primarily inorganic planting media placed on top for the planting of a carpet of pearl grass.

A network of cells in VersiDrain^® 25P act as little reservoirs to retain water which is returned, via capillary action, to the planting media during dry spells, maintaining a healthy carpet of green over the eye-catching roof of the restaurant.

An automated irrigation system was incorporated on the roof for use during the initial plant establishment and to deliver regular irrigation when necessary.

The result is a refreshing carpet of green which blends unobtrusively into the green environment of the park.

One North Residences – Singapore

To provide the Green Roof System to enable planting on the roof of the Club House beside the swimming pool of the condominium.

To prepare the concrete roof to be planted, VersiDrain^® 25P, drainage and water retention trays, were placed over the roof and covered over with a filter fabric, enabling a lightweight and primarily inorganic planting media to be installed on the trays. Regular irrigation for the selected plants, mostly drought-tolerant Sedum, is supplied by the installation of an automated irrigation system.

The green roof forms a protective shield against the elements for the waterproofing membrane on the roof and also helps to keep the interior of the Club House cool. From their windows and balconies, residents at the condominium enjoy the view of a decorative green roof instead of exposed concrete which would have been in severe conflict with the cool water and wood elements of the pool area.

Both lightweight and easy to install, Elmich Green Roof is ideal for this roof.

Bukit Timah Community Club – Singapore

To provide the Green Roof System to facilitate turfing on the rooftop of the Community Club and create additional amenity space.

A polyurethane separation sheet was laid directly over the waterproofing membrane followed by a geotextile layer as initial preparation for the concrete roof to be planted. This was followed by installation ofVersiDrain 25P, drainage and water retention trays, covered over with a filter fabric, on which regular planting media was placed and Pearl Grass planted. A water sprinkler system was installed to provide automated irrigation at each lawn section.

In addition to enhancing aesthetics and opening up amenity space, the green roof provides a protective shield that prolongs the lifespan of the waterproofing membrane. Thermal insulation afforded also helps to keep the interior space directly beneath comfortably cool and save long-term energy costs for air-conditioning. The green roof also keeps immediate surrounding ambient temperature down and Urban Heat Island effect in check.
