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.
