Throwback to Menard’s Mass Soil Mixing at the Brisbane Airport

Wheels Down! Throwback to when Menard Oceania performed its Mass Soil Mixing solution at the Brisbane Airport!

Our team was brought in to perform the Ground Improvement works on the BAC Pavement Rectification-International Airport Pavement Rectification project. The existing soil conditions were lack of bearing capacity. Mass Soil Mixing is the technique that was chosen as part of Menard’s large portfolio of techniques. Menard has established itself as a leader in Mass Soil Mixing across Oceania, successfully implementing this technique in numerous projects.

Soil Mixing (SM) is a ground improvement technique that integrates a binding agent directly with the onsite soil, enhancing its physical and mechanical properties to meet geotechnical challenges, such as the one we face at one of Australia’s busiest airports.

Why Mass Soil Mixing?
• Cost-effective: Reduces the need for importing fill material or extensive excavation.
• Sustainable: Reuses existing soil, limiting environmental disruption.
• Reliable: Provides uniform ground improvement for large-scale projects.
The Mass Soil Mixing scope of work was completed two weeks ahead of schedule. This project highlights Menard’s commitment to delivering innovative and efficient solutions tailored to complex ground conditions.

Our work involved several critical stages to ensure the project’s success:
• Performing laboratory mix trials and construction field trials to optimise the binder content and meet technical specifications for a suitable sub-grade.
• Undertaking Mass Soil Mixing in challenging ground conditions, including dredged sand and soft clay below the water table.
• Using excavators with mounted mixing tools to create a thick cement-soil stabilised sub-grade layer.
• Conducting frequency-based testing on the treated zones to verify the design intent, including Unconfined Compressive Strength (UCS), sub-grade reaction, unit weight, and secant modulus.

It’s always rewarding to see our techniques play a part in essential infrastructure projects. Have a project in mind where Mass Soil Mixing could make a difference? Let’s talk!
