RMAX GeoFoam polystyrene building blocks have been used as a high performance fill material in several civil engineering and commercial building construction projects around Australia. RMAX GeoFoam is an expanded polystyrene product featuring an excellent strength-to weight ratio that makes it the ideal choice for absorbing heavy structural and mechanical loads while reducing underlying soil stresses. RMAX GeoFoam is a preferred fill material effective in stabilising roads, steep embankments, bridge abutments and sensitive below ground pipework.
Victoria projects where RMAX GeoFoam was used as fill material include the CitiLink projects comprising of Southbank interchange; and the Power Street Bridge North Abutment, where 4,000 cubic metres of RMAX GeoFoam were used.
The Western Link Freeway Project in Victoria involved the construction of on and off ramps, where 7,000 cubic metres of RMAX GeoFoam were used.

RMAX GeoFoam also featured in the Eastern Distributor Project in NSW where the material was used for the Northern Art Gallery Overbridge in bridge voids because of its combination of light weight and strength; and the Moore Park Site where it was used in formwork for guide walls in tunnel construction.
The Port Motorway Project in Queensland used 3,000 cubic metres of RMAX GeoFoam.
The Sino Iron Project, where RMAX GeoFoam was used, is being developed at Cape Preston, 100 kilometres south west of Karratha in Western Australia's Pilbara region. This is the largest magnetite mining and processing operation under construction in Australia.
