Trusted CFA Piling Contractors in London – Strong, Quiet Foundations for Urban Sites
Welcome to KHB Piling LTD, a London-based piling
contractor providing engineered foundation solutions across the capital and the surrounding areas. We specialise
in CFA (Continuous Flight Auger) piling – a low-noise, low-vibration technique that is
particularly well suited to London’s dense, built-up locations.
Whether you are delivering a residential extension, a basement or a multi-unit scheme, our aim is the same:
a cleanly installed, fully recorded pile that Building Control can sign off without delay.
As an experienced piling contractor in London, we understand local ground conditions – from London Clay to
mixed fill and terrace gravels – and we match the piling method to the site. Our teams work with architects,
main contractors and private clients, supplying foundations that are dependable, compliant and ready for
the superstructure.
- Faster programmes – CFA rigs can install a good number of piles per day, helping you stay on programme.
- Cost-aware – no permanent casing or extensive spoil removal keeps overall costs under control.
- Quiet and low-vibration – ideal for tight terraces, mews streets and mixed-use buildings.
- Works in varied ground – London Clay, made ground and granular bands can all be handled.
- Reduced lorry movements – less excavated material means a tidier, safer site on narrow London roads.

What Is CFA Piling – and Why Is It Used So Much in London?
CFA (Continuous Flight Auger) piling is a bored piling method in which a continuous auger drills to depth
and concrete is pumped through the hollow stem as the auger is withdrawn. Because the soil is supported
throughout the operation, the bore does not collapse and there is very little disturbance to adjacent
properties. Reinforcement is placed immediately afterwards into the fresh concrete.
- it keeps noise and vibration to a minimum,
- it reduces spoil handling on site,
- it gives a uniform, in-situ pile with good load-bearing capacity.
It is therefore a sensible choice near party walls, busy streets, schools, hospitals or fully occupied
residential areas where disruption must be kept low.
How We Install CFA Piles – Our Step-by-Step Method
At KHB Piling LTD we follow a controlled, UK-standard process on every job.
1. Site and Ground Review
We look at access, headroom, drawings and any ground investigation so the pile diameter, depth and reinforcement suit the structure.
2. Continuous Drilling
A CFA rig drills to the designed depth in one operation, supporting the ground with the auger flights throughout.
3. Concrete Placement
As the auger comes out, high-quality concrete is pumped in under pressure through the hollow stem, forming the pile from the base upwards.
4. Reinforcement and Records
Steel cages are placed while the concrete is still workable. We retain piling logs so your engineer and Building Control have a full record.
This sequence gives a pile that is to depth, to line and to the specified volume of concrete.

We provide a complete service, from advice at design stage through to final pour.
- review of drawings and ground investigation,
