Solidity is an Australian-owned helical piling specialist. Since 2016 we’ve designed, manufactured, tested and installed true helical screw piles for residential, commercial, civil and energy infrastructure projects.
We do it all in-house:
• Engineering: pile design to AS 2159 by our own engineering team
• Manufacturing: Australian C350 steel and robotic welding at our Melbourne factory, scaled to deliver 6,000 piles a month
• Testing: static compression, tension and lateral load testing, plus dynamic testing and geotechnical testing
• Installation: our own crews and machines, up to 120 piles per day per rig
Clients can take the full package or any single part of it, from design through to supply-only.
Energy infrastructure is a core focus. Our piles carry 50 to 2,000 kN and sit under solar farms, battery energy storage, substations and transmission structures, including Limondale BESS, Fulham Solar Farm and the Dock Area Zone Substation.
We install across Victoria, New South Wales and South Australia and supply piles nationally. Our team of around 40 covers engineering, manufacturing and site installation.
We also built the Solidity Engineering Toolkit, a browser-based suite of pile design and site-record tools, and released it free to the industry.
