CFA
PILES

The Continuous Flight Auger (CFA) piling method is a quick and versatile solution well-suited for a wide variety of ground conditions and construction projects. The technique is virtually vibration-free, as well as being one of the quietest piling solutions, making it particularly advantageous for projects in urban settings where minimising disturbance is essential. The combination of a low level of potential nuisance and high efficiency presents CFA piles as an ideal solution for various construction challenges.

WHAT THEY’RE USED FOR

CFA piles prove their versatility by being applicable in a wide range of ground conditions, including gravels, sand, silts, clays, weak rocks, and mixed strata. This adaptability makes CFA piles a reliable choice for diverse construction projects spanning the residential, commercial, infrastructure, and industrial sectors. Whether the project needs stability in loose soils or requires penetration through various geological formations, CFA piles showcase their effectiveness as a dependable foundation solution across a spectrum of construction applications.

THE PROCESS

The CFA pile is a replacement piling technique with piles formed by augering to the required depth using a hollow stem continuous flight auger. Once at the required depth, concrete is pumped through the hollow stem whilst the auger is withdrawn at a controlled rate.

Pile arisings brought to the surface during the augering process are cleared from the auger as it is extracted from the ground, leaving a shaft of freshly placed concrete up to the piling platform level. To complete the pile formation a reinforcement cage designed for project-specific requirements is installed into the fresh concrete.
