What Is Piling?
Piling is a foundation technique used when the ground near the surface cannot support a structure’s load on its own. Structural piles — typically made from reinforced concrete or steel — are driven or bored deep into the ground until they reach a layer of soil or rock with sufficient bearing capacity. The building’s load is then transferred down through the piles to this stable layer.
Piling is used across a wide range of projects: domestic extensions where soil is soft or made-up ground is present, new-build residential developments, commercial buildings, and infrastructure projects including bridges and retaining walls. It is also commonly required where traditional shallow strip or raft foundations would be at risk of settlement or heave.
When is piling required?
A structural engineer or geotechnical survey will typically determine whether piling is necessary. Common triggers include:
Made-up ground or filled land at the site
Proximity to trees, where roots or desiccated clay creates movement risk
Soft, loose, or waterlogged soil with low bearing capacity
Existing subsidence or signs of foundation movement
Heavy structural loads that a shallow foundation cannot safely support
Construction adjacent to existing buildings where vibration must be minimised
Types of Piling We Carry Out
The correct piling method depends on ground conditions, structural loads, site access, and proximity to adjacent buildings. Pile Foundations carries out the following methods:
Mini piling
Small-diameter bored piles (typically 150–300mm), ideal for restricted access, low headroom, or domestic projects. Equipment is compact and can often work inside existing buildings.
Helical piling
Steel piles with helical blades that are screwed into the ground. No vibration, no spoil removal, and quick installation. Well-suited to soft soils and projects sensitive to noise or ground disturbance.
CFA piling (Continuous Flight Auger)
The most widely used bored pile method in the UK. A continuous auger drills to depth while concrete is simultaneously pumped through the hollow stem. Suitable for most soil types and ideal for urban sites.
Driven piling
Preformed concrete or steel piles driven into the ground by hammer. Rapid installation and high load capacity, though generates more noise and vibration. Best suited to dense granular soils away from sensitive structures.

Our Piling and Groundworks Services
As specialist piling contractors, we offer a complete range of deep foundation and groundworks services for residential and commercial clients across the UK.
Helical Piling
Helical piles (also known as screw piles) are a low-vibration, low-disturbance foundation solution. The steel piles are rotated into the ground using a torque head mounted on an excavator. Because they generate no spoil and minimal noise, helical piles are particularly well suited to urban domestic projects, extensions close to neighbouring properties, and sites with restricted access. Installation is typically complete within one to two days for a residential project.
Underpinning
Underpinning is used to strengthen or deepen the foundations of an existing building — typically where subsidence, ground movement, or adjacent excavation has compromised the original foundation. Pile Foundations carries out traditional mass concrete underpinning as well as beam and base underpinning and pile and beam systems, selected according to the cause of movement and the structural requirements of the building.
Foundation Contractors
We design and install bespoke foundation systems for new-build domestic and commercial projects. This includes reinforced concrete pile caps, ground beams, ring beams, anti-heave measures, and pile-supported raft systems. Our in-house engineers produce all structural calculations and drawings, meaning architects and developers can procure design and build from a single contractor.
Concrete Finishing
We provide reinforced concrete slab installation and concrete finishing for ground-bearing and suspended floor applications. Our teams work to tight tolerances on level and finish, producing durable results suitable for residential, commercial, and industrial use.
Basement Construction
Pile Foundations designs and constructs basement shells for residential extensions and new builds, including contiguous bored pile walls, reinforced concrete slabs, and waterproofing systems. We manage the full structural package from initial engineering through to finished shell, coordinating closely with architects, party wall surveyors, and main contractors.
Piling Contractors Across the UK
Pile Foundations operates from four regional bases, covering London, the South West, and the Midlands. Our teams are experienced in the specific ground conditions and planning requirements typical to each area.
Piling Contractors in London
London’s dense urban environment presents specific challenges for foundation work: restricted access, proximity to existing structures, deep clay soils subject to shrink-swell movement, and the presence of the London Underground and other utilities at depth. Our London team works extensively with architects and structural engineers on residential extensions, basement projects, and commercial developments, using low-vibration methods including helical piling and CFA piling where sensitivity to adjacent buildings is a concern.
Piling Contractors in Bristol
Bristol’s ground conditions vary significantly across the city — from the soft alluvial soils of the river valley to sandstone and limestone in elevated areas. We regularly work on domestic underpinning and extension projects in older terraced properties, as well as commercial and mixed-use developments in Bristol’s expanding urban fringe. Our Bristol team carries out site investigations and provides foundation design as part of a full design-and-build package.
Piling Contractors in Exeter
Exeter and the wider Devon region presents a mix of red sandstone, mudstone, and river alluvium. Our South West team handles residential piling, underpinning, and foundation projects throughout Exeter, Plymouth, Taunton, and the surrounding areas, often in older properties where subsidence or poor original foundations require remediation.
Piling Contractors in Birmingham
Birmingham and the wider West Midlands sits on a complex mix of coal measures, clays, and made-up ground, particularly in areas of former industrial use. Pile Foundations has experience working on brownfield sites requiring ground investigation and bespoke piling solutions, as well as residential new-build and extension projects across the region.
