Piling is one of the best techniques to provide essential support for any construction. Wherever there is the presence of soil at the construction site that cannot support the necessary weight for the building at a not-so-deep depth, this technique gets used. In this scenario, the piling method helps to set deep foundations which support the construction in an ideal way. Therefore, it is essential to pick the right piling contractor with the right equipment set and a skilled workforce to launch the structure. Using continuous flight auger (CFA) piling is efficient and proves beneficial.
In this blog, we will understand the benefits of piling contractors and then talk about continuous flight auger (CFA) piling.
Benefits Of Piling Contractor

One of the tools used by the piling contractor is the continuous flight auger (CFA) piling.
Let’s get to know more about it.
What Is A Continuous Flight Auger (CFA)
The CFA comprises a helical auger similar to the household screw. It extracts the soil once drilled onto the ground through a circular motion to extract soil. Once done with the extraction of ground, concrete gets injected with high pressure via a hollow central stem, fed slowly while the auger gets removed.
Advantages Of CFA
- Minimum vibration levels
- Lower Noise levels
Disadvantages Of CFA
- Installation takes eight weeks and is expensive.
- Contaminated soil may slow down your projects as it needs to be attended to on priority before the actual work commences.
- Underwater piling may be challenging without the installation of steel casings. There is always a risk of collapsing the pile bore. The process also demands long piles than driven, resulting in more prolonged continuous noise exposure.
- CFA piling requires more construction traffic.
