CFA Piling
Continuous flight auger (CFA) piling is a method of foundation installation that is used in poor ground conditions, for specific below-ground strata formations, on made ground, or at sites with high water tables. It involves drilling and concreting at the same time, resulting in much faster installation.
Piled Solutions is a CFA piling specialist for Chelmsford, Colchester, Croydon, Harlow, Harrow, Haywards Heath, Romford, St Albans, Tunbridge Wells, Wimbledon and the surrounding areas.
We take on high-value projects and smaller jobs, with expertise in commercial requirements. The types of projects and buildings we work on include schools, blocks of flats, and new build developments, among many others. We also specialise in helical screw piles and subsidence treatment.
A hollow-stemmed auger is rotated into the ground to the design depths before concrete is pumped through the hollow stem and the auger is extracted simultaneously. We then insert steel reinforcements into the wet concrete.
This type of foundation installation is suitable for most ground conditions and construction projects, including soils with clay, sand, silt, gravel and soft rock. Common applications for CFA piling include:
Our piling contractors drill and concrete CFA piles as part of a single and continuous process, which enables faster installation times compared to traditional bored piling.
Because we use reinforcement immediately after casting, CFA piling can accommodate significantly higher structural loads.
Continuous flight augers are track-mounted rigs suitable for use in tight spaces with low headroom clearance.
With minimal noise and vibrational output, this method is particularly suited to built-up urban areas and sites with higher-than-average groundwater levels.
Piled Solutions oversees the entire installation process. Our track-mounted rigs use innovative monitoring equipment during CFA piling to guarantee good auger rotation, high penetration rates, accurate depths, perfect extraction and the correct concrete pressures. We achieve quality assurance through non-destructive testing, inspection and pile integrity.
Our company meets the foundation installation needs of customers in Chelmsford, Colchester, Croydon, Harlow, Harrow, Haywards Heath, Romford, St Albans, Tunbridge Wells, Wimbledon and all the surrounding areas.
