Bored piles are generally for bearing upon however a common use is also to provide a retaining wall by means of contiguous piles or King post piling.

Piling is generally to diameters 300mm to 750mm and depths up to 34 metres.

Kelly bar short stem bored piles is a traditional means of piling in clays.

It has the advantage of being able to bore an open hole with tools which can socket or core into bedrock for better bearing.

Our rigs have telescopic Kelly bars which can bore up to 34 metre depth.

This system is used for King Post Construction where a wall is formed by means of panels of precast concrete installed between the posts which generally are steel columns concreted into the bored holes at 3-4 metre centres.
