Green Roof

A ‘Green Roof’ development involves the creation of vegetated space integrated structurally on top of a structure. The word ‘roof’ in this context refers to any continuous surface designed for the protection of inhabitants from the elements, whether open or closed on the sides. The vegetated space may be below, at, or above grade, located on a podium deck, a ‘sky garden’ on an intermediate floor level, or at the very top level of the building, but in all cases the plants are not planted in the ground. Freestanding planters placed on top of a roof do not constitute the recognised international landscape industry definition of a green roof, which is characterised by the integration of the vegetation containment structure with the building roof structure.

- vegetation on the roof, local specsies are recommended to use
2. Substrate (View graphical detail)
- a mixture of growing media supplying water and nutrients
3. Filter Sheet (View graphical detail)
- filtering the non-watersoluble material to remain on the roof
4. Drainage Board (View graphical detail)
- to drain excess water to prevent prolonged saturation
5. Protection Moisture Mat (View graphical detail)
- protecting the layer below and storing water and nutrients
6. Root Barrier (View graphical detail)
- preventing the roots growing into the waterproofing material
7. Structural Deck with waterproofing

Slope roof

Geo Synthetic Cell system is designed for sloping roof. It is a matrix of lightweight, expandable and flexible thermoplastic strips (View sample here) that are ultrasonically bonded to form a strong, dimensionally stable and inert honeycomb structure. The thermoplastic strips do not have perforations to ensure optimum strength of each cell.

When filled with substrates, the system creates a three dimensional barrier and structural bridge that uniformly distributes weight-bearing loads and enhances drainage and prevents build-up of hydrostatic pressure.

Features & Benefits

- Perforated cell walls
- Unrestricted grass runner and root growth
- Achieve greater soil depth
- Can be installed in layers or stacked
- Withstands high weight bearing loads
- Distributes weight bearing loads
- Resists downward and lateral pressure and movement
- Avoids need to construct load support structures
- Prevents infill from being forced into substrate
- Easily dismantled and re-used
- Minimal Maintenance


- Slope stabilization and protection
- Earth retention on retaining walls and embankments
- Load support on driveways, maintenance roads, parking lots, cart paths, walkways,
  pipeline/sewerage supports and channel crossings
- Channel and shoreline protection on river banks, scour aprons, boat ramps and spillways
- Planting media containment on sloping extensive green roof or wall


- Provides cost effective, long-term slope protection and stabilization
- Ease in transportation and on site handling due to collapsible cells
