We are experts in CFA auger design and manufacturing. CFA is becoming more and more popular because it is a fast and effective drilling technology that allows you to drill the pile in one shot. The concrete is pumped directly through the centre of the auger when removing it from the ground which makes it a fast drilling method. CFA has very minimal vibrations during the drilling process and because there is no need to work with bentonite or polymers, there is almost little or no effect on the environment. The CFA flight sections come in various diameters and lengths depending upon the machine to be mounted on and torque output. We utilize a hexagonal coupling system to insure a maximum and well sealed connection between the flights. Various drilling teeth and bits can be mounted on CFA augers according to your requirements.
