Driving Melbourne’s Critical Infrastructure with Proven Thermal Sand Solutions
At GPQ, we are proud to be supplying high-quality thermal sand products to projects across all three major Melbourne growth corridors, while also servicing customers throughout regional Victoria, from projects as far as East Gippsland, Seymour, Melton and Geelong.
Our thermal sand range has been developed to meet the increasing demand for engineered backfill materials used in specialised construction and infrastructure applications.
GPQ currently offers three thermal sand products, including:
✔️ Washed Thermal Sand – perfect for high volume projects including solar and BESS, achieving TR ratings below 1.1 K•m/W
✔️ Screened Thermal Sand – ideal for stringent TR requirements like data centres and HV cable embedment projects, achieving TR ratings below 0.9 K•m/W - consistently one of the lowest on the market
✔️ Additional thermal sand products tailored to project requirements
As the use of thermal sand products continues to grow across the construction industry, GPQ is actively investing in the development of new products and specifications to support emerging markets and specialised applications.
