Screw Piling
Screw piling is a versatile and efficient foundation solution that provides reliable support where traditional concrete foundations may not be suitable. Also known as helical piles, screw piles are installed quickly, minimise disruption and are ideal for both residential and commercial projects.
At Capital Piling, we supply and install screw piling systems across London and the South East. Our team works closely with clients, engineers and contractors to deliver a dependable foundation solution tailored to your project requirements.

Fast Installation
Minimal Ground Disturbance
Immediate Load Bearing
Typical Applications for Screw Piles:
Screw piling is used across a wide range of foundation projects where a precise, engineered solution is required. It provides dependable load-bearing support for both temporary and permanent structures.
Residential extensions and new-build homes
Commercial and mixed-use developments
Basement and underpinning projects
Modular and prefabricated buildings
Projects near existing structures requiring controlled installation
Is Screw Piling Right for Your Project?
Screw piling is often specified where traditional foundations are not suitable due to access restrictions, Tree Preservation Orders (TPOs) or third party wall constraints. Because installation involves minimal excavation and significantly reduced vibration, it is well suited to projects close to neighbouring properties or within protected root zones.
The process also produces very little spoil, making it a more environmentally considerate foundation option. Suitability will depend on ground conditions and structural requirements. Our team can review your project details and advise whether screw piling is the most appropriate solution.

What Is Screw Piling?
Screw piling uses steel piles with one or more helical plates welded to a central shaft. These are rotated into the ground using hydraulic equipment, advancing through soil layers until they reach the required depth and load-bearing capacity.
The helical plates transfer load into competent soils, making them suitable for a wide range of ground conditions. Because installation does not require excavation or concrete pouring, screw piles can be installed quickly, with minimal spoil and reduced site disturbance.
As the piles are loaded immediately once installed, follow-on trades can continue without delay

We install structural screw piles in 60mm, 76mm and 89mm shaft diameters, commonly specified for residential developments, new build properties and light commercial structures.
These pile sizes are suitable for engineered foundation solutions where controlled installation and verified load capacity are required.

Installation Equipment
Depending on site access and structural requirements, piles are installed using:
Depending on site access and structural requirements, piles are installed using:
Handheld hydraulic drive units for restricted or internal access locations
Excavator-mounted hydraulic torque heads for higher load capacities and deeper installations
We coordinate with structural engineers and Building Control where required to ensure compliance and approval.
Screw piling is commonly specified for extension and infill projects across London where planning constraints, neighbouring properties and protected areas influence foundation design.
Tree Preservation Orders (TPOs) - Provides a low-impact foundation solution within protected root zones where excavation must be carefully controlled
Party Wall Situations - Offers a controlled, low-vibration installation method suited to projects close to adjoining properties
Environmental Considerations - Reduces excavation and concrete usage compared to traditional trench foundations
Why Engineers Specify Them - Allows load capacity to be verified during installation, providing confidence in constrained urban ground conditions.
This makes Screw Piling a Reliable Choice for many London piling projects, it offers a straight forward solution where traditional foundations are simply not suitable.

Why Choose Screw Piling?
Screw piling offers a reliable and efficient alternative to traditional foundation methods. Its controlled installation process and adaptable design make it suitable for a wide range of residential and commercial projects.
Screw Piling offers several practical and technical advantages:

Engineered and Verified Installation
Minimal Disruption
Immediate Structural Support
Adaptable to Project Requirements
Suitable for Protected and Sensitive Areas
How Screw Piling Is Installed
Site Review & Design Input
Ground information and structural load requirements are reviewed to confirm the appropriate pile specification, diameter and installation criteria.
Positioning & Setup
Specialist hydraulic equipment is positioned over the pile location, ensuring accurate alignment in accordance with the foundation layout.
Mechanical Installation
The pile is rotated into the ground using calibrated machinery. Installation torque is continuously monitored to verify that the required load capacity is achieved.
Final Depth & Connection
Once the design depth and resistance are met, the pile head is prepared and fitted with the appropriate bracket or connection detail, ready for immediate construction to commence.

Frequently Asked Questions
Navigating foundation solutions requires expert insight. Explore our answers to common queries. We address installation timelines, costs, and suitability for restricted access sites.
What is mini piling?
Mini piling is a specialised foundation solution using high-strength, smaller diameter piles. They tend to be between 100mm and 450mm. The method is for sites with restricted access, low headroom, or poor soil conditions. These can make traditional piling impossible. Mini piling is the industry standard for stabilising existing structures (underpinning). It's also used for building house extensions and working within tight urban footprints.
Do you offer quotations/price match quotes for mini piling projects?
Absolutely. We provide fully itemised, transparent quotations. Our team tailors these to your specific ground conditions and structural requirements. We are committed to offering the best value in the market. If you receive a written quote from a comparable provider for the same specification, we aim to match that price. Call us at 0333 202 6412 for a no-obligation assessment.
When can you start/finish work for mini piling projects?
One of the key benefits of mini piling is rapid mobilisation. Our compact rigs are easier to transport and set up than heavy machinery. This means we can often begin work sooner than traditional piling contractors. Project duration depends on the number of piles and ground depth, but we pride ourselves on efficient turnaround times. Contact us today to check our current lead times and secure your slot.
Do I need to hire any additional equipment for mini piling projects?
No, we provide a complete end-to-end service. Our fleet includes state-of-the-art, self-contained mini piling rigs. These are capable of fitting through standard doorways and operating in confined spaces. We supply all necessary grout pumps, reinforcement cages, and ancillary tools. This ensures you face no hidden hire costs or logistical headaches.
Is mini piling noisy, or will it cause vibration damage to existing structures?
Mini piling is explicitly designed as a low-vibration solution. This makes it the safest option for working adjacent to existing foundations, party walls, or in dense residential areas. Our bored piling techniques cut into the ground rather than hammering it. This is unlike traditional driven piling, which relies on heavy impact. It significantly minimises noise pollution and ground movement. This protects the structural integrity of your property and prevents disturbance to neighbours.
Can mini piling be used in difficult ground conditions or clay soil?
Yes. Mini piling is exceptionally versatile and effective in challenging soil profiles. This includes loose gravel, "made ground" (rubble), and shrinkable clay prone to subsidence. We employ specialised techniques to prevent borehole collapse in unstable soil. These include using temporary casings. Such ensures we can achieve the load-bearing capacity and protection against ground heave. This is even in cases where standard trench footings would fail.
