GENERAL SPECIFICATIONS UPDATED 06.2018

Roof Gardens

.... we are committed to providing sustainable living roofs for healthy, ecologically responsible buildings.

Extensive Roof Gardens PROFILE DEPTH: 140mm - 200mm

From the new residential home to greening a garage roof or home extension – all the way to an extensive roof on a large commercial building – extensive roof gardens are the latest in the sustainability tool kit for acoustic and temperature insulation, water management and aesthetic beauty.

Extensive and semi-extensive roof gardens have a thin growing medium <200mm deep, planted with predominantly native vegetation.

Fytogreen designs roof gardens specifically to suit the site conditions, inclusive of weight and set down limitations. All Fytogreens roof gardens are irrigated and designed for low maintenance.

PLEASE NOTE: We do not supply the waterproof membranes, however we will direct you to the most suitable membrane systems.

1. Extensive Roof Garden (140-200mm Profile)

Typical Specification

1.1 LDPE layer at a minimum of 200 micron. This layer is 200-300mμ thick with a gsm of approximately 200gm. The function is a protection layer to the membrane at the initial installation stage, as well as a long term root protection layer for the membrane.

1.2 Drainage Cell: 20mm Atlantis Flo Cell 20 The drainage cell is HDPE with a crush strength of 200kPa and is fungus resistant. The thickness is 20mm with a weight of 1500gsm. Flo cell will hold 1.8lt/m2 of water in the cupʼs for re-absorption by roots when required.

1.3 Geofabric: Bidim A14-A24 Bidim “A” is a non-woven, needle punched, continuous filament, polyester textile made in Australia from recycled polymer. The geofabric layer is 2mm thick and has a wet weight of 360gsm.

1.4 Hydrocell 40 Extensive Media Hydrocell 40 Extensive Media is a proprietary engineered combination of scoria in two size grades (other mineral material is used where scoria is not economically available), composted pine bark and hydrocell flakes. The thickness is specific to the weight allowance for the project, but as a quick check guide 11kg/m2/10mm of depth as a saturated weight allowance.

The function is to provide a very lightweight, non hydrophobic low organic content media that is stable over time, has excellent capillary properties for sub surface irrigation, good shear strength due to particle shape for sloped surfaces and is suitable for a wide range of plant species.

1.5 Stone Mulch Layer: 20mm scoria, recycled concrete or basalt. 14-20mm material is used as a stone mulch in a range of locally available materials.

Functions are to reduce the opportunity for blow-in weed species to readily establish as well as provide a stable ballast layer protecting the substrate layer during plant establishment from excessive wind.

1.6 Sub Surface Drip Irrigation Netafirm R Techline AS with emitter spacing of 150mm and a flow rate of 1lt / emitter / hr. buried 30-40mm in the media profile at 400mm row spacing will ensure a uniform moisture application.

1.7 Plants A wide range of plant species can be selected subject to the site and climatic conditions at a range of densities to fit the client expectations. (Contact Fytogreen for a detailed design)

1.8 Optional Item: L-Profile Edge 1.2mm Stainless Steel edge profile to retain the garden from the box gutter.

The standard height is 150mm, with vertical slits for fast water penetration, folded along the top edge for improved rigidity. L-Profile is made to order, so height options available.

The L-Profile has holes in the base, so it can flashed welded or sikaflexed into position on the underlying membrane, ensuring no penetrations through the membrane.

The parapet edge should ideally be a minimum of 20mm higher than the garden.

1.9 Saturated Weight Allowance Guide (see following page) • Extensive Weight Guide

140mm to 200mm

NB: Water proofing and independent certification of the water proof membrane is “work by others”

Intensive Roof Gardens, Podium and Planter Boxes PROFILE DEPTH: 200mm -1500mm +

Intensive roof gardens are typically heavier than extensive gardens, with a garden profile depth of 200-1500mm+ supporting substantial vegetation, shrubs and trees – a landscaped space for people to use for recreation, gardens or a natural habitat.

Fytogreen are proud to have supplied over 550,000m2 of roof gardens and roof garden media components throughout Australia . We assists landscape architects, garden designers and supplies components to landscape contractors for intensive roof gardens.

PLEASE NOTE: We do not supply the waterproof membranes, however we will direct you to the most suitable membrane systems.

Fytogreen Australia - providing sustainable solutions for the built environment

An extensive and intensive roof garden installed in a restricted access security area at the USA Embassy in Canberra, comprising of a combination of paved, lawn and garden areas.

The planting design combines Australian natives with a lawn area migrating through to succulents within the thin profile sections of the roof.

Fytogreen designed and constructed this roof garden in collaboration with SIKA and ILD. SIKA and ILD provided products and services to complete the waterproof membrane and assist in complying to the single source green roof delivery specification.

2. Fytogreen Intensive Roof Garden, Podium and Planter Box (200mm Plus Profile)

Typical Specification2.1 LDPE layer at a minimum of 200 micron.

This layer is 200-300mμ thick with a gsm of approximately 200gm. The function is a protection layer to the membrane at the initial installation stage, as well as a long term root protection layer for the membrane.

2.2 Coreflute protection board Minimum 2.5 mm for vertical planter wall membrane protection.

2.3 Drainage Cell: Atlantis Flocell 20 drainage cell The drainage cell is HDPE with a crush strength of 200kPa and is fungus resistant. The thickness is 20mm with a weight of 1500gsm. Flo cell 20 will hold 1.8lt/m2 of water in the cusp’s for re-absorption by roots when required. Flow rate of 200lt/min at a 1% gradient.

2.4 Geofabric: Bidim A14-A24 Bidim “A” is a non-woven, needle punched, continuous filament, polyester textile made in Australia from recycled polymer. The geofabric layer is 2mm thick and has a wet weight of 360gsm.

2.5 Hydrocell RG30 – Water Reservoir Layer Hydrocell is a proprietory urea aldehyde resin based hardfoam that is either manufactured directly onto the roof or delivered in a pre-manufactured sheet composition, as either a 60mm or 100mm layer.

The dry weight is 4kg/m2, which is complemented by it’s ability to absorb water into the open cell structure to reach a field capacity weight of up to 55kg/m2.

The functions of the layer are numerous: • Water reservoir of up to 51lt/m2 at field capacity per 100mm • Fines filter, protecting the geofabric layer from blockage of media fines. • Excellent growing media in it’s own right,

with a balanced air water ratio at field capacity. • Non-hydrophobic, so can be easily re-wet if the situation arises. • Excellent capillary properties enabling water

to be moved upwards through the profile.

The Hydrocell RG30 layer is made up of interconnected small to medium cells or pore spaces, enabling the usable media volume to be approximately 99%.



2.6 Hydrocell 40 Lightweight Planter Media Hydrocell 40 Lightweight Planter Media is a proprietary engineered combination of medium washed sand and scoria (other mineral material is used where scoria is not economically available), composted pine bark and hydrocell flakes. The thickness is specific to the weight allowance for the project, but as a guide 12kg/m2/10mm of depth as a saturated weight allowance.The function is to provide a lightweight, non hydrophobic low organic content media that is stable over time, has excellent capillary properties for sub surface irrigation, good shear strength due to particle shape for sloped surfaces, high hydraulic conductivity and is suitable for a wide range of plant species.

2.7 Stone Mulch Layer: 20-40mm scoria, recycled concrete, bluestone or basalt. 20-40mm material is used as a stone mulch in a range of locally available materials.

Functions are to reduce the opportunity for blow in weed species to readily establish as well as provide a stable ballast layer protecting the substrate layer during plant establishment from excessive wind.

2.8 Plants A wide range of plant species can be selected subject to the site and climatic conditions at a range of densities to fit the client expectations.Controlled release fertiliser is selected to suit the plant species planted.

2.9 Sub-surface irrigation Fytogreen in conjunction with Netafim Australia design and install irrigation systems to suit the site requirements.

Geoweb® Cellular Confinement

The Geoweb® system is the most advanced soil stabilization technology available on the market today. Initially developed by the US army to allow trafficking of heavy vehicles over very soft ground.

The Geoweb® system consists of a flexible, high-strength network of interconnected cells that confine and stabilize soil. Geoweb® is widely used around Australia as a support platform in unsealed roads, on slopes and in low velocity channels.

A variety of infill materials can be used depending on the problem, including topsoil with selected vegetation, sand and gravel, larger rock and stone and concrete.

The system is made from high quality polyethylene in collapsed, lightweight panels that are easily and safely handled on-site. Geoweb® has a solid reputation for quality and innovation and is manufactured to the highest international standard with ISO9001:2008 accreditation.

Geofabrics supports the Geoweb® system with design and support and installation tools.

Geofabrics also offers additional technical support for the selection of the cell depth and anchoring system, based on the conditions of the application.

A four person crew from Fytogreen was able to install the Geoweb® Cellular Confinement System within four working days. The crew divided the tasks into two separate components. Two workers ran the tendons through the cells, whilst the additional two workers installed the ATRA® keys to secure the adjoining panels to each other along their longitudinal edges.

The growing media was stored in bulk bags, and lifted above the system by a mobile crane for installation. The Fytogreen installation team was then able to spread and foot compact the growing media, as the slope was considered too steep for the use of compaction equipment.

The Geoweb® Cellular Confinement System’s unique design provides resistance to sliding for thin soil veneers on steep slopes, which ultimately allowed for the construction of a previously unfeasible, living green roof on a 20° slope.

Project: Victorian Desalination Plant Date: October 2012 Client: Fytogreen Location: Wonthaggi, VIC

The Victorian Desalination Plant, located in Wonthaggi Victoria, was commissioned to supply an additional 150 billion litres/year of drinking water to Victoria’s water system. One of the highlights of the desalination plant is the living green roof, which is the largest in Australia.

Fytogreen was awarded the contract for the 26,000m2 living green roof, which consisted of various plant species, all indigenous to the local environment. The majority of the living green roof was constructed on slopes less than 15°, and did not require any specialised construction techniques for veneer stability. However, approximately 650m2

of the roof was to be constructed on a 20° slope, which required additional consideration for the stability of the growing media.

The Geoweb® Cellular Confinement System was selected for use on the 20° slope, as the unique tendon anchoring system resists sliding forces on steep slopes, which would otherwise be subject to veneer failure.

The Geoweb® Cellular Confinement System is available in cell depths ranging from 75mm to 200mm. Selection of the cell depth and anchorage requirement is related to the steepness of the slope, angle of repose, depth and density of the infill material. A cell depth of 150mm with 10kN/m tendons running down the slope, placed in every second cell across the slope was selected for the living green roof application.

Sloping Roof Gardens SUPPORTING SLOPES FROM 15° TO 45°

Fytogreen support the use of ‘The Geoweb® Cellular Confinement System’s for any roof garden with a slope above 15 degrees.

This unique design provides resistance to sliding for thin soil profiles on steep slopes, which ultimately allows for the construction of a previously unfeasible, living green roof up to a 45° slope. The design is ratified by Geofabrics Australia.

Roof Garden Media HY40 LIGHWEIGHT PLANTER MEDIA MIX

Hydrocell 40 Lightweight Planter Media is a proprietary engineered combination of medium washed sand and scoria (other mineral material is used where scoria is not economically available), composted pine bark and hydrocell flakes. The thickness is specific to the weight allowance for the project, but as a guide 12kg/m2/10mm of depth as a saturated weight allowance.

The function is to provide a lightweight, non hydrophobic low organic content media that is stable over time, has excellent capillary properties for sub surface irrigation, good shear strength due to particle shape for sloped surfaces, high hydraulic conductivity and is suitable for a wide range of plant species.

Fytogreen’s Hydrocell growing medium is tested in a variety of climatic and planting conditions, assisting in conserving waterand providing a most efficient water-saving systems available.

Water Reservoir Layer HYDROCELL RG-30

Hydrocell is a proprietary urea aldehyde resin based hardfoam that is delivered in a pre-manufactured sheet composition.

The dry weight is 4kg/m2/100mm, which is complemented by it’s ability to absorb water into the open cell structure to reach a field capacity weight of up to 55kg/m2/100mm. The Hydrocell RG30 layer is made up of interconnected small to medium cells or pore spaces, enabling the usable media volume to be approximately 99%.

Available in 30mm, 60mm or 100mm depths.
