Continuous Flight Augering, also known as auger cast piling, is a technique used to created concrete piled foundations.
CFA (continuous flight auger) piles are drilled and concreted in a single continuous operation, which allows a much faster installation process than bored piles. Reinforcement is added into wet concrete after casting which permits the pile to withstand the full range of structural loading. The process of CFA piling involves rotating a hollow stem continuous flight auger into the soil, to a certain depth, before concrete is then pumped through the hollow stem to fill the cylindrical cavity made by the auger, as the auger is gradually removed. The reinforcement cage is then set down through the freshly placed concrete.
Rotary piling can be used to support a structure where the highest load carrying capacity is required.
RBP (rotary bored piling) involves a piling rig which uses specific drilling tools, such as augers and buckets, in order to remove soil and rock. These specially designed tools are used to bore into the ground continuously, which removes spoil. The pile is progressed until the desired depth is reached. This form of piling is used for large commercial and industrial sites, public buildings and transport infrastructure. The method includes screwing a temporary steel sleeve into the ground whilst an auger is used to dig out the inside of the casing. The reinforcement steel cage is then placed into the bore after the pile toe level has been reached. Concrete is then poured using a tremie-pipe which is when the steel casing can be removed.
