SFA piling: the restricted access piling technique
Working in urban environments or confined spaces calls for a piling technique that fits the bill. Sectional auger piling is an excellent alternative for getting reliable results even in restricted access areas.
Restricted access
The auger sections can be transported and assembled on-site, allowing for piling operations in confined spaces or areas with limited headroom.
Versatile
SFA is supplied in small sections, requiring a short mast on the piling rig. However, the number of sections added to the rig can exceed the depth CFA piling can achieve.
Cost-effective
Smaller plant requirements typically mean smaller costs. SFA piling is often a more cost-effective option, especially for restricted access projects.
Advanced installation process
Our installation process uses modern rigs equipped with Non-Destructive Testing (NDT) instrumentation. This technology monitors key parameters such as pile depth, penetration rate, drill resistance, concreting pressure, and extraction rate, which allows for efficient control throughout the installation process.
Quality assurance
Bespoke to your requirements
Every SFA piling solution we deliver is tailored to your project’s specific needs. Our in-house team ensures each design and installation meets the highest standards for quality, safety and performance. Plus, all our rigs are equipped with onboard systems to monitor concrete depth in real time for high levels of accuracy and control on site.
Health & Safety at the core
As a leading provider of piling and ground beam solutions, safety is built into everything we do. Our team works to a safety-first culture, supported by industry accreditations and rigorous internal standards
Environmental responsibility
We’re focused on reducing the environmental impact of every project. Our SFA piling methods are designed for low-noise, low-vibration performance, and we continuously seek ways to cut carbon, reduce waste, and support your long-term environmental goals.

What is sectional flight auger piling?
Sectional flight auger piling is a form of replacement piling. Like continuous flight auger piles, they work by replacing the ground with a column of concrete to form the foundation.
CFA vs SFA piling: which is best for my project?
The main difference between CFA and SFA piling is that SFA piles are constructed with sectional augers (usually supplied in 1-2m lengths). The augers are incrementally introduced as the pile advances, providing more control over the depth of the piles.
How are SFA piles installed?
We install SFA piles by drilling a hollow stemmed auger into the ground. We then inject concrete through the hollow stem as the auger is withdrawn, before inserting a reinforcement cage. During SFA piling installation, we can add and remove augers to achieve the required design depth.
Why choose Green Piling for sectional flight auger piles?
With over 25 years of specialist experience, Green Piling is one of the UK’s most trusted providers of SFA piling. We offer a fully in-house service, from design and estimating to manufacturing and installation, giving you full visibility, consistent quality, and expert support at every stage.
We invest in advanced piling rigs equipped with modern, computerised systems that monitor auger depth, rotation speed and penetration rate in real time. This ensures every pile is installed with precision, control and full compliance with industry standards.
