Boral Concrete – CFA Piling & Retaining Wall Construction

Location

Geelong, VIC

Scope of Works

• CFA piling using specialised auger equipment
• Installation of steel posts for retaining wall system
• Concrete placement during drilling process
• Excavation and benching to maintain safe working areas
• Coordination with concrete supply for continuous pours

Outcome

The retaining wall system was constructed to support changes in ground levels and stabilise the surrounding area, ensuring long-term durability and site safety.

Despite tight access conditions and operating alongside an active facility, the project was delivered safely, efficiently, and to program, showcasing Mellis Earthworx’s capability in large-scale industrial piling and retaining solutions.

This project at Boral Concrete in Geelong involved the delivery of CFA piling and retaining wall works within a live industrial environment. Mellis Earthworx completed the drilling and installation of piles to support structural loads and create a stable retaining system.

Using a continuous flight auger (CFA) piling method, piles were installed efficiently by drilling and concreting in a single operation, ensuring minimal vibration and disruption to surrounding infrastructure.
