Screw Piling from Belowground

At Belowground, we can implement a range of piling techniques to provide innovative foundation and underpinning solutions, where we use modern rigs that are suited to the majority of ground conditions.

Screw foundations are particularly useful due to their ability to perform in all soil types. They are effectively screwed into the ground, much in the same way that a screw is wound into a plank of wood. This is a highly efficient, clean and quick means of installation that can be accomplished with minimal vibration and noise. Once the screw pile has been deployed, its helix shape then serves to disperse the building load.

How Does a Screw Pile Work?

The piling used in screw pile foundations is made from galvanised hollow steel sections. Each section has at least one helix attached (if not more). The recommended type of helix will vary depending on the soil conditions, where we will analyse the needs of your site in order to find the right solution for you. Once the piles are deployed, these helices serve to hold them at a constant pitch.

Screw piling installations are typically completed with the use of powerful hydraulic motors. These exert an enormous amount of torque while the pile is screwed into the ground. We will bring this equipment to your construction site and secure it against heavy-duty handling machinery, such as excavators or mast-mounted crane rigs.

One of the most critical considerations has to do with the interface between the helical screw piles and the structure that is being built over the foundation. Our highly qualified technicians have experience completing this kind of work across all of southern England, so you can rest assured that your building is in safe hands.
