Auger boring specialists across New Zealand
Auger boring is a trenchless method used to install larger diameter pipelines over longer distances. Using a rotating cutting head, we bore through the ground while removing spoil, making it a dependable option for straight, accurate runs.
It’s the method we turn to when the job calls for size, length, and consistency. At United Tunneling, we handle auger boring projects with the right gear and know-how to get through the ground cleanly and efficiently, without unnecessary disruption above.
How auger boring works
Auger boring is a trenchless method used to install larger diameter pipelines by rotating a cutting head through the ground while removing spoil through a hollow auger system. The pipe is simultaneously jacked forward from a launch pit, allowing for a controlled and efficient installation.
It is best suited to straight runs where ground conditions allow for stable, continuous boring over longer distances.
Large diameter pipeline installation
Ideal for installing larger pipes for water, stormwater, and utility infrastructure.
Road and rail crossings
Used to install pipelines beneath transport corridors with minimal surface disruption.
Long straight installations
Well suited for projects requiring consistent alignment over longer distances.
Industrial and civil infrastructure
Commonly used in infrastructure upgrades, subdivisions, and industrial developments.
Stable ground conditions
Performs best in ground that allows for steady boring and spoil removal.
Deep pipeline installations
Suitable for projects requiring deeper installation beneath surface infrastructure.
Benefits of auger boring
Tough jobs, done well.
Auger boring – what you need to know
What is auger boring used for?
Auger boring is used to install larger diameter pipelines underground, often for water, stormwater, and utility services.
When is auger boring the right choice?
It’s best suited to long, straight runs where ground conditions allow for steady, controlled boring.
Can auger boring be used under roads or rail?
Yes, it’s commonly used for crossings beneath roads, rail lines, and other infrastructure without disrupting the surface.
What ground conditions does it work in?
Auger boring performs best in stable ground conditions where the bore can be maintained without collapse.
How accurate is auger boring?
It provides good alignment for straight runs, though it’s not as highly controlled as microtunneling for precision work.
