Advantages of a Continuous Flight Auger (CFA) System

There are several reasons why the use of a CFA system is beneficial. They can be installed quickly and quietly, with low levels of vibrations and are also an environmentally friendly option. Unlike displacement type piles, CFA piles have a very low risk of ground displacement or loose soil that becomes solid causing damage to any neighbouring foundations or utilities.

Another advantage of using a CFA system is that it is possible to monitor the entire installation process of the piles. A flow meter provides accurate data that is then recorded and can be analysed. Information that is collected includes penetration/uplift per revolution, auger depth and injection of pressure at the head of the auger.

The CFA system also has an excellent rate of installation success so it is definitely an option worth considering.
