Screw piling can be used for a wide range of applications and is essential for the successful installation of builds such as bridges, wind turbines, temporary structures, tree roots, building foundations and much more.
WHAT ARE SCREW PILES?
Screw Piling is a method which is used to build deep foundations in a range of soils. Screw piles can be installed quickly and with minimal noise and vibrations. They are wound into the ground similar to how screws are wound into wood which is an efficient means of installations. They also hold a mechanism of dispersing load which gives them their outstanding in-ground performance.
Screw piling is subject to building regulations and requires approval from local building control inspectors. Structural Repairs handle the liaison with building inspectors and arrange the required inspections as part of the service. Get in touch today for a free consultation!
HOW IS SCREW PILING CONDUCTED?
Screw piles are circular and hollow steel screw tubes which hold one or more helices on their outer surface. As opposed to auguring through the soil it is being penetrated into, screw piles cut into it following a constant pitch. The helices the screw piles hold are design specifically to suit the desired ground conditions. The pile is able to remain permanently fixed in place once it was reached the desired ground depth as they are typically filled with concrete. The protruding pile is able to provide a connection between the building above and the ground it is cemented into which in many cases increases the capacity of the pile.

How much does Screw Piling cost?
Screw piling costs vary on the depth and size of the pins as well as the ground conditions and soil conditions. Screw piling costs would start from £575 per pile.
Advantages of Screw Piling
One of the major advantage of screw piling is that it can be installed quickly and with minimal noise and vibrations. In addition, screw piles are also able to be driven at any angle to suit any desired design needs. Screw piles are can accept loads in either tension or compression and are able to accept full loads immediately after installation.
Uses of Screw Piling
Screw piling a build would be undertaken in order to build a deep foundation. It is also a fantastic method to use on a range of soils, including earthquake zones with liquefaction potential. The process of screw piling strengthens the existing foundations of a build and stabilizes against movement. Screw Piles are repeatedly specified as the foundation of choice for building in tree protection areas.
Screw Pile FAQs
We’re here to help! Here you’ll find the answers to the questions we get asked the most about screw piles. If you would like to know more, get in touch for a free consultation.
- What is the screw piling process?
Screw piles are wound into the ground in a similar way to how regular screws are wound into a wooden surface or wall. Once in place, the screw piles are filled with concrete as a means to firmly stabilise them. The protruding pile is then able to provide a connection between the build above and the ground it is cemented into.
- What does screw piling mean?
Screw piling is when a build’s or structure’s foundation is deepened or better secured. As opposed to other foundation securing methods, screw piling can be installed quickly and with minimal noise and vibration. It can be applied to a wide variety of structures such as tree roots, bridges, wind turbines, temporary structures, tree roots, building foundations and much more.
- How much does screw piling cost?
Depending on the level of service you’re looking for, screw piling comes in many different forms and with varying price tags. Each method can be used for different structure types, different materials, and will also depend on the current foundation and its materials. When carrying out screw piling procedures on your property, it is important to note that you may require consent. Screw piling costs would start from £575 per pile.
- What are the advantages of screw piling?
Screw piling can be installed with great ease given that few machinery is utilised and is a project which can be completed in a timely manner. It is also a method which has a low carbon footprint, therefore making it more environmentally friendly then other similar solutions available. Screw piling is a process which does not require soil to be removed from site, making it relatively mess-free. Screw piles are able to be installed in close proximity to existing structures and can be easily removed when they are no longer needed. Another major advantage of screw pilling is that it can be installed with minimal noise and vibrations. In addition, screw piles are also able to be driven at any angle and can accept loads in either tension or compression to suit any desired design needs. Piles are able to accept full loads immediately after installation meaning they can get connected and be ready to use instantly.
- What machinery is used to implement screw piles?
To drive and secure a pile into the ground powerful hydraulic motors are used to apply the large torques which are required as part of the process. The hydraulic motors are fastened onto handling machines that range in size, according to the size of the structure. To connect the pile to the structure under question geotechnical and structural input is required as a means to understand the structure and the ground which the piles are being driven into.
