Screw Piles

What are screw piles?

Screw piles are a type of deep foundation consisting of hollow steel shafts with helical flights, of various sizes, that are installed (or screwed) into the ground to the required design depth.

The winding action used to install the piles is quick and occurs with minimal noise and vibrations.

Once at their target depths, the hollow steel shafts are filled with concrete and provide the connection to the supporting structure above. They are ideal for supporting building foundations and, because of the low noise and vibration installation, are ideal for projects within the established urban environment.

Also, due to the low ground disturbance during installation, they are suitable for sites where the minimisation of spoil is important, e.g. contaminated sites. Additionally, we can install screw piles with a range of different sized equipment, meaning that they can be installed in hard to access spots.

Applications Include

Technical Information

Built to industry standards
Can be designed for a range of different soil types and loading scenarios
Can be connected to the building foundation through a direct connection or by using steel reinforcing bars cast into the top of the pile
Corrosion is addressed either by allowing for a sacrificial thickness of steel or by adding a surface coating to provide protection
Designed following the New Zealand Building Code

Do you make these products yourself?

We can manufacture screw piles in-house to suit the required design using various pile shafts and helix diameters. The helix is welded to the pile shaft by our qualified welders, adhering to our strict weld procedures, ensuring you receive a pile of the highest quality standard.
