Guided auger boring

Directional Auger Boring is a fully guided trenchless technique carried out between two prepared shafts, which are usually manholes. The Directional Auger Boring rig is set up in the launch shaft and the guided probe is then jacked through the ground to the reception shaft using laser guidance.

Steel casings carrying auger flights are progressively installed following the pathway made by the guided probe. An upsizing motor is attached to the last auger. As the upsizing motor is jacked into the ground product pipes are progressively installed at the launch shaft. The augers and casings are progressively removed at the reception shaft. On completion of the pipe jacking process the upsizing motor is removed and the pipe jacked to its final position. Pipes installed can be steel or vitrified Clay.

Guided auger boring is the quickest and a cost-efficient way to install sewers, ducting and pipework. It's also the most environmentally friendly method too. it causes minimal disruption to road users, pedestrians and surrounding areas and less disruption to the environment.
