Hardings Hotmix birds eye view of site

Hardings Group is a locally owned and operated Tasmanian specialist civil contracting and asphalt business.

Starting out in 1986, as a two-man operation working on private driveways, Hardings Hotmix spent the following years growing and branching out into new areas, as new opportunities in the industry were identified. In 2011 with the addition of the Asphalt Batch Plant, Hardings Hotmix became a key Asphalt supplier on the North West Coast of Tasmania.

In early 2021 Hardings Hotmix was merged with CBB Contracting, then acquired by Sonic Civil Investments. With 3 years of growth, 2024 began with a rebranding of the Hardings Hotmix business name to Hardings Group which better reflects the diverse range of services we offer and supports our direction of growth in the construction industry.

We remain committed to the tradition of growing to meet industry needs and identifying opportunities to improve performance. Today, the Hardings Group employs a workforce of over 100 and services Tasmanian water, sewerage, roads, urban, rural, industrial construction, and infrastructure sectors.
