CFA Piling – Expert Continuous Flight Auger Foundations for Your Project

At Ancora Foundations Ltd, we specialise in CFA piling (Continuous Flight Auger piling), providing high-performance, precision-engineered foundation solutions across Sussex, Kent, London, and the South East. Our CFA piling contractors combine technical expertise, modern equipment, and in-depth geotechnical knowledge to deliver vibration-free, cost-effective, and structurally robust piles tailored to your project’s specific requirements.

The Process & Benefits

Continuous Flight Auger (CFA) piles are installed using a hollow-stem auger that drills to the design depth. During extraction, high-quality concrete is pumped through the auger stem, forming a continuous pile, into which a steel reinforcement cage is inserted. This method ensures consistent pile quality, superior load-bearing capacity, and minimal ground disturbance, making CFA piling an ideal choice for residential developments, commercial buildings, basements, retaining walls, and civil infrastructure projects.

  • Expert CFA piling contractors experienced in both domestic and large-scale projects
  • Vibration-free, low-noise piling methods perfect for urban or sensitive environments
  • Rapid installation with minimal disruption to your site

Services FAQ

For sites with limited access or low headroom (like basements or rear gardens), we use SFA (Segmental Flight Auger), Grundomat, or Helical piling. These methods utilise compact, handheld, or modular equipment that avoids the need for large rigs.

We use ODEX piling for challenging strata. This method cases the hole simultaneously while drilling, preventing bore collapse in loose soil and allowing us to penetrate through boulders, fill, or rock obstructions securely.

Yes. Beyond piling, our Reinforced Concrete (RC) teams construct piled rafts, ground beams, and retaining walls. This ‘one-stop’ approach ensures seamless integration, faster delivery, and clearer accountability for your project.

Absolutely. We specialise in vibration-free and low-noise techniques (such as CFA, SFA, and Helical piling) that protect adjacent structures and minimise disruption to neighbours, fully compliant with environmental standards.

Yes. We design and install Contiguous and Secant piled walls to retain earth and exclude water for basement excavations. These are engineered to withstand high lateral loads and integrate with the final structure.

We operate with strict adherence to Eurocode 7, BS EN standards, and NHBC requirements. We provide full design warranties, collateral warranties, and comprehensive Quality Assurance (QA) logs for every pile installed.
