Direct Mix Group

Thebarton, SA 5031



Direct Mix Concrete is your local South Australian ready mix concrete supplier, established in 1961. Proudly using locally sourced materials, Direct Mix is a subsidiary of Adbri Limited. We provide government, local construction businesses and builders with the highest quality ready mix concrete supplies, backed up by technical expertise and exceptional customer service, on and off site.

For almost 60 years, Direct Mix Concrete has partnered with businesses to successfully complete the most technically challenging projects, from the construction of concrete bridges on the Northern Expressway through to submerged concrete structures at locks along the Murray River. The low shrinkage aggregate, sourced from our own quarries and used in all of our ready mix concrete supplies, has become an imperative for these major projects.

Direct Mix is one of South Australia’s largest concrete suppliers. Our local quarries and plants operate within environmentally sustainable principles to supply metropolitan and regional areas of the state.

Southern Quarries Pty Ltd and Direct Mix Concrete are committed to fostering a sustainable future. From energy efficient lighting to water recycling and land recovery, our processes minimise our impact on the environment. Through positive business partnerships, we aim to support construction projects that benefit our community environmentally, socially and economically.

Driving Sustainability

With an eye on the future, we have initiated the following processes, operations, and facilities to minimise our impact on the environment:


Rainwater is captured, stored and used at all facilities

Waste water is recycled through settlement ponds and used at all concrete plants, including for vehicle wheel wash

We use dry produced, manufactured sand in our concrete and supply dry screened natural sand from our Peninsula Quarries sand mine at Price. These important measures eliminate the need for washing sand with water, and avoid associated environmental impacts such as silt dams.

We use environmentally safe Polo Citrus products, made from natural orange oil, for dust suppression at our crushing plant at Sellicks Hill, saving thousands of litres of water per year.

Oil, Fuel and Energy

Our energy efficient machinery uses alternative fuels such as Adblue

Used oil is collected for professional recycling by a third party

We use energy efficient lighting in our offices.

Land Recovery

We have purchased and revegetated more than 300 acres of buffer land surrounding the Sellicks Hill Quarry

Our Sellicks Hill and Price Quarries have been revegetated with native plants. 

Community and Compliance

We protect our local environment and community by ensuring all vehicles used at our quarries enter a wheel wash facility, which uses recycled water to minimise ‘drag out’ of dirt and mud onto public roads.

We comply with all relevant legislation, standards and codes of practice.
