Root Barrier, Drainage Modules, Bentonite, Grass Pavers
Vercan root barrier is made in Australia from recycled HDPE. It is a tough material and can be easily bent around corners or cut with a utility knife. Vercan is manufactured in two types dimpled and textured. Some landscapers and councils prefer the dimpled as they believe the dimples act as more of a deterrent because roots tend to follow a smooth material whereas the roots will go off in another direction with a dimpled sheeting.
We stock 300mm, 600mm, 900mm, 1200mm wide in both standard and dimpled. These are available in 10m and 30m length rolls.
Sodium bentonite is often specified to be used as a root inhibitor for root barrier installations. Typically when using sodium bentonite as a base for root barrier a mixing ratio of 1:15 (bentonite to soil) for good quality soil or 1:10 ratio for poorer earth. You will need approximately 5kg per 10m of root barrier, allowing for a 50mm depth x 100mm width of bentonite/ soil mix.
If you are using bentonite clay as a repair for earth dams a common mix is 20kg soil to 1kg bentonite.
Our sodium bentonite is a civil engineering grade (see brochure for specifications) and is suitable for drilling, dam repairs and root barrier.
VesiCell offers architects and developers greater design flexibility and has a wide range of applications in the landscape, building and construction industries.
VersiCell® is a lightweight interlocking plastic structural module used for subsurface drainage or to form tanks for underground water percolation systems.
When installed with a waterproof membrane, VersiCell® eliminates the need for an additional protection layer.
VersiCell® modules are easily interlocked in the same plane (a) or at right angles (b) to one another. They may be butted together without interlocking.
Greater design flexibility as the modules may be interlocked in one plane or at right angles to one another to form continuous large panels, conduits and tanks.
Easy Installation Large easy-to-join modules or pre-assembled panels allow rapid installation and minimise on-site disruption.
Lightweight and High Strength Honeycomb design results in a lightweight high compressive strength structure.
The modules are resistant to biological attack and to a wide range of chemicals.
High surface void area and internal void volume results in efficient drainage. Narrow profile enables a greater soil depth to be utilised in planter beds allowing the use of a wider variety of landscape plants.
VersiCell® is manufactured from high strength recycled plastics.

Versidrain Dimpled Sheeting
Versidrain’s integrated non-woven geotextile covering the dimples prevents soil particles from blocking the drainage sheet, creates an air gap for ventilation, and allows the inflow and transport of water from surrounding soil.
VersiDrain 8 Geo is installed with the geotextile facing the backfill.
Typical areas of application include:
- Retaining and basement walls
- Tunnels and landfills
- Paved areas
- Roof gardens and landscaped decks
Provides and efficient drainage system for underground structures
Acts as a protection layer over waterproof membranes
compressive strength permits usage in moderate load bearing situations of up to 250kN/m² (25t/m²)
Wide and easy to handle rolls result in rapid and low cost installation
TurfPave Modular Grass Pavers
Turfpave is a tough product which provides architects and developers with a vehicle resistant grassed alternative to concrete, stones and asphalt pavements.
Turfpave XD: A tough Grass Paver which provides architects and developers with a vehicle resistant grassed alternative to concrete, stones and asphalt pavements. Manufactured from 100% recycled polypropylene. TurfPave XD is suitable for both soils and gravel.
Turfpave Grass Pavers are a permanent lightweight and practical, aesthetically pleasing, and environmentally friendly alternative to concrete pavers. Grass Pavers are quick to install and being light they require less handling and labour.
Positioned under the grass surface, Turfpave Grass Pavers distribute loads from traffic including vehicles and pedestrian to the basecourse below. This has the effect of minimising grass and root compaction. In addition the interconnected cells allow roots to develop with minimal restriction resulting in a durable and stable grass surface which is able to withstand heavy loading.
Turfpave Grass Pavers enhance our environment by allowing the creation of stabilised and durable lush lawns which add to the quality and beauty of the environment.
