surface stabilisation

The GEOHEX™ Erosion Control System is an Australian-made plastic grid turf and substrate stabiliser that has a huge variety of uses across a range of applications and industries. Made from 100% recycled post-consumer plastics, GEOHEX™ is a sustainable and more cost effective substitute to concrete and bitumen-type products.

By increasing the structural integrity of the soil, GEOHEX™ Erosion Control System helps stabilise infill material, mitigates erosion, and controls shearing, lateral and vertical movement in a wide range of soil and substrate types. GEOHEX™ creates a stiffened base layer that provides increased load support whilst preventing soil subsidence and erosion.

With a maximum load bearing capacity of 1200t/sqm when filled and made from recycled and recyclable interlocking polypropylene hexagonal cells, GEOHEX™ is suitable for use in just about any type of ground and geological conditions.

recycled Posts, bollards and sleepers

A unique and CSIRO tested co-mingled plastics recycling technology developed in Australia is now available from Holloway Group. The plasmar range of 100% recycled plastics fence posts, bollards and sleepers are bacteria and rot resistant, long lasting and demonstrate significant benefits over timber in agricultural, civil, residential and commercial applications.

Built upon 17 years of research and development, plasmar products are free from additives like lighteners and UV stabilisers, with the product's strength, durability and shelf life a result of the engineering and industrial strength polymers used in their manufacturing

Visit the plasmar website for more information on the range and it's applications.

Residential slab reinforcement

The residential building industry has been called to adopt more sustainable alternatives to polystyrene wafflepods which can have detrimental effects on the environment, communities and surrounding flora and fauna when it becomes damaged or is blown away by wind.


Expensive to transport and difficult to store, traditional wafflepods have been an ongoing challenge for builders for years, but with waffle pods meeting current building codes, the industry has continued to use them. Biax Foundations is changing the game with its next generation of residential slab void, known as the Biax Foundations System. Biax pods are made from 100% recycled plastic, stack and store neatly and have proven to be a simple and effective system to install.
