Contaminated ground mitigation
As a true soil-displacement method, our screw piles generate no spoil or bore arisings. That greatly reduces the risk of environmental cross-contamination and the cost of hazardous landfill levies.
What we install
Screw Piles Ltd provides principal contractors, structural engineers and commercial developers with a complete, end-to-end foundations package: full technical design, load verification, materials supply and precision installation.
Helical screw piles carry heavier structural loads, and alongside high-capacity helical anchor systems our experienced operatives engineer the reinforced concrete ground beams and capping rafts that sit on top. Our screw piles are built to the highest standards, to ISO 9001 and CE standards. We work across London, the South East and East Anglia, with nationwide coverage.
For site managers and engineers
As a true soil-displacement method, our screw piles generate no spoil or bore arisings. That greatly reduces the risk of environmental cross-contamination and the cost of hazardous landfill levies.
Fast-cycling, low-access installation suits highways, rail frameworks, telecommunications infrastructure, high-mast signage and gantry foundations.
Helical piles can be mechanically reversed out of the ground without leaving buried concrete behind, making them a sustainable foundation for temporary events, site accommodation and modular commercial buildings.
Our screw piles are built to ISO 9001 and CE standards, and our work conforms to ISO 9001 quality management systems. Installation torque is monitored continuously with CE approved instrumentation, giving instant, field-verified compression and tension capacities against the project parameters.
Typical commercial work
Screw pile foundations are used across a range of industries, from road and rail to telecommunications.
Foundations for extensions to commercial buildings, installed close to existing structures with no vibration.
Easy to remove when no longer needed, which makes them excellent for temporary use.
No spoil to remove from site, saving waste landfill costs.
Foundations for civil engineering, water treatment and other utilities.
Cost-effective solutions for road building and railway projects.
Including electrification network expansion.
Foundations for large signs, designed for vertical and lateral forces such as wind.
Underpinning in new build work, and piling close to existing structures.
Tree root avoidance support systems.
Proven on site
One of the big advantages of screw piles is that we can check how much weight each one will carry while we are putting it in. A gauge on the machine measures how hard it has to work to turn the pile into the ground.
The harder a pile is to turn, the more weight it can hold. So we know straight away that every pile is strong enough, and we check the readings against the design worked out for your ground.
Access & sustainability
Our equipment is small enough for most sites. The piles are turned in by a mini digger of 1.5 to 5 tonnes, fitted with a powerful, CE approved drill head. Where there is no room for a digger, or the piles are going in inside a building, we use smaller equipment that is carried in by hand.
The piles themselves are made from recycled steel. When they are no longer needed they can be unscrewed and used again, just as strong as before, so nothing has to be left in the ground.

0330 043 3216Yes. Screw piles are unusual among piling types in that they can be loaded immediately after installation. There is no need to wait for concrete or grout to harden.
Load capacity is a function of the torque required to install the pile, considered together with the design load based on the subsoil values. In most soil conditions, particularly cohesive soils, the ultimate capacity increases slightly with time.
Piles are normally installed by a mini excavator fitted with a low-speed, high-torque hydraulic drill head, turning at 6 to 10 rpm. Typically only an operator and one assistant are needed.
Yes. Screw piles can be removed as easily as they were installed, which makes them especially useful for supporting temporary structures.
