Screw piling: How Does it Work?

Screw piling is a widely used technique, both for creating and strengthening the foundations of structures from domestic homes to major infrastructure projects.

There are many different approaches to inserting piles.

So, what is screw piling and how does it work?

What Are Screw Piles?

Screw piles are steel shafts inserted into the ground, in segments joined together, which are then filled with concrete or grout to support the structure above.

Screw piles are a type of deep foundation that can be installed quickly with minimal noise and vibration.


How Do Screw Piles Work?

Screw piles are wound into the ground by earthmoving equipment.

During installation, the screw piles cut into the soil as opposed to auguring through it. The shafts and helical flight are designed to suit the different ground conditions. Once the pile has reached the target depth, it is typically filled with concrete and permanently remains in place.

Why is Screw Piling Used?

Screw piles have been used for nearly two hundred years, traditionally for building roads and railways, as well as other major engineering projects.

More recently though, screw piling has been used in various contexts within domestic homes, including sheds, decking and stairs.

This is because screw piling is quicker and easier to install than any other type of piling. It also requires a relatively small amount of equipment and involves less soil displacement than other methods, meaning it is a cheaper and more environmentally friendly method.
