Auger Bored Mini Piles are generally used in cohesive soils where segmental augers are rotated into the ground and the soil being penetrated is flighted to the surface by the augers.
Where the ground is unstable, temporary casing can be installed in conjunction with the augers to progress the bore. When the predetermined pile length has been achieved, the steel reinforcement is placed and the pile bore is filled with either concrete or grout.
This technique is most suitable for cohesive soils and is particularly time efficient and cost effective where open boring is possible.
Our powerful, high torque minipiling rigs can install piles diameters up to 600mm in restricted access and headroom environments.
