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

CFA PILES ARE A TYPE OF DRILLED FOUNDATION IN which the pile is drilled to the final depth in one continuouus process cusing a continouous flight auger

CFA piles - drilled by continuos flight auger system - combine the advantages of the driven piles with the veracity of the bored piles. The drilling method allows to excavate in a wide of soils, dry or water logged, loose or cohesive and also to penetrate through low capacity, soft rock formations such as loamy clays, limestones and sandstone, etc

CFA diameter range from 400 to 1400 mm
