We’re proud to announce the completion of one of Butler Excavations’ most significant and technically demanding projects to date.
Situated in the steep terrain of Lorne, this project involved constructing three large-scale 3-meter high retaining walls across tiered levels at the rear of three adjacent residential properties. The works were designed not only to mitigate pre-existing landslide risks but also to create flat, usable land in preparation for future residential development on each block.
The site posed significant challenges, such as dense vegetation, excavation through hard clay and rock, and limited access for machinery and trucks due to the steep natural site slope and the close proximity of existing dwellings on two of the properties. Nevertheless, the works were carried out to a high standard of engineering and quality, with safety consistently prioritised throughout the project.
Scope of Work Highlights:
• Clearing and grubbing resulting in the removal of 7 truck-and-trailer loads of green waste
• Excavation and disposal of over 3,400 m³ of fill material and 44 tons of concrete
• Supply and installation of 160 galvanized UC steel posts (100–200 mm wide, up to 7.2 m long), each placed in 450 mm diameter footings at depths of up to 3.5m
• Placement of approximately 100 m³ of structural concrete
• Installation of over 1,750 charcoal concrete sleepers (120 mm thick)
• New water supply and drainage infrastructure integrated into site works
• Carpentry works including 160 lineal meters of timber paling fencing, 140 lineal meters of timber balustrading for fall over protection, and staircase construction
• Landscaping to finalise and stabilise the site
This project demonstrates our capability in delivering complex earth retention solutions in sensitive and high-risk environments. If you’re planning a retaining wall installation—whether residential or commercial—reach out to Butler Excavations to ensure it's built right.
