SFA piling is created by drilling sectional augers flights into the ground. The sides of the hole are supported at all times by the soil, auger or placed concrete, eliminating the need for the temporary casing or bentonite slurry. Upon reaching the required depth, sand-cement grout or concrete is pumped down the auger flight filling the pile, whilst the augers are steadily and slowly withdrawn. Once filled reinforcement is immediately placed into the pile.
With powerful rigs it's possible to construct large diameter piles with relatively small rigs making us able to cope with whatever your project requires.
