Explore the helix geometry, material strength and installation benefits of Multiturn Screw Piles, from load capacity to removal and reuse.
What sets it apart
Multiturn Screw Piles combine patented helix geometry, cast steel and a three-stage installation process. The system supports a range of load requirements while allowing removal and reuse.
Handles heaving clay, acid sulphate soils, and areas prone to subsidence, without compromising structural integrity.
Easy to install and reuse, Multiturn Screw Piles leave a lighter footprint than traditional concrete-based foundations.
Light to heavy-duty shaft sizes and wall thicknesses, suitable for both round and square configurations.
Multiturn Helix Screw Piles present a substantially lower environmental risk than concrete-based foundation systems.
There are no chemical additives introduced into the soil, no risk of concrete leachate entering the water table, and no disruption to the soil structure or the organisms that inhabit it. Because the piles can be fully removed at end of use, the long-term footprint on the site is minimal.
Sensitive sites · contaminated ground · strict remediation
Despite their low environmental impact, Multiturn Screw Piles remain suitable for heavy load applications.
A range of light to heavy-duty steel shaft sizes and wall thicknesses can be specified to meet varying load capacity requirements, with compatibility across both round and square shaft configurations. This flexibility allows the system to be engineered to the specific demands of each project rather than applying a one-size-fits-all solution.
Round and square shafts · light to heavy duty
The helical form of the pile base creates a screw effect that works in both directions.
Piles can be cleanly extracted and relocated without damage to the surrounding ground. Structures such as site sheds have long relied on this system precisely because the pile and helix can be unscrewed and moved to a new location as required.

The reduced diameter of the Multiturn Helix — which provides a 2x bulb factor — represents a 30% cost saving on materials compared to traditional screw pile designs.
Combined with the ability to certify load capacity, eliminate the need for load testing, and re-use piles across multiple projects, the system delivers measurable value for builders and project managers across the project lifecycle.

The helix edge
The Multiturn Helix is the core of what makes this system work.
The reduced diameter of the Multiturn Helix represents a 30% cost saving on materials compared to traditional screw pile designs.
As the pile is driven into the ground, the helix penetrates clays, gravels and shales, displacing loose material rather than disturbing the surrounding soil profile. Unlike a standard plate helix, the Multiturn cutting edge is capable of penetrating up to 4 MPa rock.
The steel used throughout (Cast Steel Alloy ASTM 216 WCB) offers a yield strength range of 300 to 600 MPa, effectively negating the risk of catastrophic pile failure.
