Auger boring is a trenchless method used for installing underground pipelines or conduits. It involves using a continuous flight auger, which resembles a screw, to bore a hole through the ground. A pilot tube is typically installed first, followed by the auger which excavates the soil and transports it to the surface.

This process is carried out from within a jacking pit. The auger's rotation creates a hollow path. Once the desired length is excavated, the product pipe or casing is pulled or pushed through the open hole behind the auger. The soil removed by the auger is then disposed of.

Auger boring is suitable for a variety of soil conditions, including sand, clay, and gravel. It is often employed in urban areas where open trenching would cause significant disruption. The method is known for its accuracy in maintaining alignment and grade.

Advantages of auger boring include minimal surface disturbance, reduced impact on existing infrastructure and traffic, and the ability to install pipes under roads, railways, and other obstacles without excavation. It is generally considered a cost-effective solution for certain types of installations. However, it is not suitable for very long distances or in areas with obstructions like large boulders or bedrock. The size of the pipe that can be installed is also limited by the auger diameter and the jacking pit size.
