Engineered Precast Solutions for Infrastructure Projects

Our specialist engineering and manufacturing teams work closely with clients from concept design through to installation. We provide tailored precast concrete solutions that meet project-specific requirements relating to structural performance, durability, constructability and aesthetics.

Using advanced design and manufacturing processes including 3D modelling, mould design, concrete mix optimisation, lifting design and in-house concrete testing, Geoquest delivers reliable and efficient precast products for some of Australia’s most challenging infrastructure environments.

Bridges, Tunnels and Transport Infrastructure

Geoquest is recognised for delivering innovative precast solutions for bridges, overpasses, underpasses and tunnels. Our patented TechSpan® precast concrete arch system has been used on major road, rail and mining projects, including installations spanning up to 21 metres, making it one of the most advanced precast arch solutions available in Australia. TechBox™ structural box culverts and trapezoidal culvert systems provide efficient solutions for pedestrian crossings, rail underpasses, drainage structures and transport corridors. 

Retaining Walls, Noise Barriers and Architectural Precast

In addition to structural infrastructure components, Geoquest manufactures a range of retaining wall systems, noise barriers and decorative precast solutions. Our T-Wall® modular gravity retaining wall system and TechWall™ counterfort retaining wall system provide robust solutions for road and rail grade separations, embankments and earth retention applications. FanWall™ noise barriers deliver effective acoustic protection, privacy and security while supporting a variety of architectural finishes.
