Bored pile are drilled using buckets and/or augers driven by percussion boring (vibratory hammers) or through rotary boring (twisting in place).

Maximum Pile Diameter/ Depth: Ø2500mm / 100m
In unstable soil strata, the use of bentonite fluid assists in stabilising the bore especially in large diameter deeper piles and allows the insertion of heavily reinforcing steel cages. This is known as flush boring (see more below).
