Rotary Bored / Cased Piles

Rotary Bored Piles are usually employed for large commercial and industrial developments, public buildings and transport infrastructure projects. Quinn Piling has developed specialist expertise in delivering large, complex and technically challenging projects.

Basic Technique

An auger is used to excavate the earth, whilst a steel sleeve is inserted to maintain the bore through the top layers of unstable ground. A steel cage or pattern of reinforcing rods is introduced into the bore before the concrete is poured. The steel sleeve is later withdrawn.
