Standard Auger

CFA pile is drilled to the predetermined design depth in one continuous process using a continuous flight auger.
Concrete is then pumped under pressure down hollow stem of the auger to the bottom of borehole. Once pumping starts, the auger is progressively withdrawn, bringing soils with it to the surface.
When the auger and its load of soil are finally removed, reinforcement elements to meet the design requirements are placed in the concrete pile.
Continuous Flight Auger (CFA) piles are installed without significant vibration or excessive noise produced.

Standard auger is provided with bottom concrete exit with steel plug & recovery chain.
