Bored Piles are non-displacement piles capable of carrying large vertical loads and are particularly efficient and cost effective when boring into cohesive soils.
Pile diameters range from 300 mm to 4.0 m.
Pile lengths to a depth of 90m.
Rig weights range from 11t to 180t.
Bored Piles offer larger diameter piles than any other piling method and permit pile construction through particularly hard strata. Where unstable strata is encountered temporary or segmental casing and permanent steel liners, bentonite slurry or polymers may be used for bored piling.
Bored Piling is a popular foundation system for bridges and tall buildings. It is also applicable to retaining walls, secant, contiguous and soldier pile walls.
Bored piling is a progressive system of drilling and withdrawing the auger until the desired depth of pile is reached. In most cases excavated material is being verified and the pile base is cleaned before placing the reinforcement steel and pouring the concrete.
