CFA PILING

The Continuous Flight Auger (CFA) piling method is a fast and adaptable approach that is highly effective across a broad range of ground conditions and construction scenarios.

This technique generates minimal vibration and is one of the quietest piling options available, making it especially beneficial for urban projects where reducing disruption is crucial. The blend of low disturbance and high efficiency makes CFA piles an excellent choice for addressing diverse construction challenges.

WHAT THEY’RE USED FOR

CFA piles demonstrate their versatility by being suitable for a broad spectrum of ground conditions, such as gravels, sands, silts, clays, weak rocks, and mixed strata. This adaptability makes them a dependable option for various construction projects, ranging from residential and commercial to infrastructure and industrial sectors. Whether a project requires stability in loose soils or needs to penetrate through different geological formations, CFA piles prove to be an effective and reliable foundation solution for a wide array of construction applications.

THE PROCESS

The CFA pile is a replacement piling method where piles are created by drilling to the desired depth with a hollow stem continuous flight auger. Upon reaching the required depth, concrete is pumped through the hollow stem as the auger is carefully withdrawn at a controlled pace.

The material displaced during the drilling process is removed from the auger as it is extracted, leaving behind a shaft of newly placed concrete up to the level of the piling platform. To finalize the pile formation, a reinforcement cage, tailored to the project's specific needs, is inserted into the fresh concrete.
