The Helical Pile

What a helical pile is
A helical pile is a steel shaft with one or more helix-shaped bearing plates, screwed directly into the ground rather than poured or driven into place. The helix bears on the soil the way a screw thread bears on timber, which is why the technology has held up in the ground since it was first used in the 1800s, long before “screw pile” was a modern buzzword.

The Helical Pile, by FTA
FTA’s Helical Pile is our flagship system, installed and refined since 2012 in accordance with Australian Standards. It’s the default technology for the widest range of soil conditions, particularly lower-strength, less dense or fill soils where a shallower ground screw won’t achieve the required bearing.

Why it works
- Installed with verified torque on every pile — capacity confirmed as it goes in.
- No concrete, no curing wait, immediate load-bearing capacity.
- Fits residential, modular, commercial and infrastructure applications alike.
Where it’s used
Modular schools, mining camps, battery storage sites, government housing, and homes — over 3,000 projects across Victoria and Queensland.
Location coverage
With an established presence in Victoria and Queensland, we mobilise nationally for large-scale projects.
