CFA Piling (Continuous Flight Auger)

CFA piling is a widely used foundation solution for apartment schemes and larger commercial developments. The process involves drilling and filling the pile with concrete in one continuous operation, creating strong reinforced concrete foundations that safely support the structure above.

At Capital Piling, we deliver CFA piling on projects of all sizes - from single residential builds to larger multi-unit and commercial developments. Each pile is designed to suit the specific ground conditions, structural requirements and overall needs of your project.

Typical Applications for CFA Piling:

CFA piling is frequently selected where vibration control, ground stability, or structural loading influence foundation design.

Residential developments and large scale developments

Commercial and mixed-use buildings

Industrial buildings and warehouse units

Sites with clay, made ground, or variable soil profiles

Sites with variable or challenging ground conditions

Is CFA Piling Right for Your Project?

CFA piling is commonly used where ground conditions require bored pile construction and reduced vibration compared to driven systems. It provides consistent structural performance across a wide range of soil types.

The most appropriate piling method depends on site constraints, load requirements, and engineering design. Our team will review your project and advise on the most suitable foundation solution before any commitment is made.

What Is Continuous Flight Auger (CFA) Piling?

CFA piling is a bored piling method where a hollow stem auger drills to depth before concrete is pumped through the auger as it is withdrawn. This creates a continuous reinforced concrete pile without leaving the bore open.

Its controlled installation process makes it particularly suited to urban environments and sites where ground movement must be carefully managed.

About CFA Piling

Why Choose CFA Piling?

Continuous Flight Auger (CFA) piling is often selected when a project needs a deep foundation solution that can be installed in a controlled and efficient way, particularly on built-up sites.

CFA piling offers several practical and technical advantages:

Reduced vibration compared to driven piling methods

Consistent pile formation through continuous concrete placement

Suitable for a wide range of ground conditions, including London clay and made ground

Efficient installation for programme-sensitive projects

Adaptable pile diameters and depths to suit structural design requirements

How CFA Piling Is Installed

Site Investigation & Design

Ground investigation data, structural loading requirements, and project constraints are reviewed to confirm pile type, diameter, depth, and layout.

Continuous Flight Auger Drilling

A hollow-stem continuous flight auger is rotated into the ground to the specified depth. The soil is supported by the auger flights during drilling.

Concrete Placement

Concrete is pumped through the hollow stem of the auger as it is steadily withdrawn. This controlled process maintains positive concrete pressure.

Reinforcement & Completion

Immediately after concreting, the reinforcement cage or steel section is inserted into the fluid concrete to the required depth

Ground Beams & RC Slabs

Mini piling can be delivered to suit your project scope and stage:

Mini piling only – where ground beams or slabs are providedseparately

Mini piling with RC ground beams and/or RC slabs – a fully coordinated package

RC ground beams and RC slabs only – where piling has already been completed

This flexibility allows us to integrate seamlessly with existing teams or deliver a complete foundation solution under a single contract.
