Reliable pipe jacking across New Zealand

Pipe jacking is a trenchless method used to push pipes through the ground with controlled force, allowing for accurate underground installation without the need for open trenches. It’s a solid option for projects where space is tight and disruption needs to be kept to a minimum.

At United Tunneling, we use pipe jacking to keep jobs moving where traditional methods would slow things down. With the right setup and an experienced crew, we deliver reliable installations across a range of conditions, keeping things precise and efficient from start to finish.


How pipe jacking works

Pipe jacking is a trenchless method used to install pipelines underground by hydraulically pushing pipes through the ground from a launch pit to a receiving pit. It allows for accurate installation without the need for continuous open trenching, making it ideal for confined or sensitive environments.

The pipe sections are jacked forward one at a time as excavation occurs at the face, with spoil removed as the system advances. This provides controlled alignment and reliable installation across a range of ground conditions.

Urban infrastructure installation

Ideal for installing water, sewer, and stormwater pipelines in built-up areas where open trenching isn’t practical.

Road and rail crossings

Used to install pipelines under major transport corridors without disrupting traffic or surface infrastructure.

Accurate pipeline alignment

Provides reliable control over line and level for projects requiring engineering precision.

Medium-distance pipeline installation

Well suited to longer runs where consistent alignment and controlled installation are required.

Tight or restricted sites

Works well in confined areas where access is limited and surface disruption must be kept to a minimum.

Benefits of pipe jacking

Minimal surface disruption above ground.

Accurate line and level control underground.

Works well in urban and built-up areas.

Safe installation under roads and infrastructure.

Reliable option for confined or restricted sites.

Tough jobs, done well.

Pipe jacking – what you need to know

What is pipe jacking used for?

Pipe jacking is used to install pipelines underground without open trenching, commonly for water, sewer, and stormwater systems in urban or restricted areas.

How does pipe jacking differ from microtunneling?

Pipe jacking is the method of pushing pipes through the ground, while microtunneling uses a remote-controlled machine for higher precision. The right method depends on the project requirements.

What ground conditions can pipe jacking handle?

It works across a range of ground conditions, with the setup adjusted to suit the soil and site requirements.

How many pits are needed?

Typically, a launch pit and a receiving pit are required, which keeps surface disruption to a minimum.

Is pipe jacking suitable for urban areas?

Yes, it’s well suited to built-up environments where space is limited and digging long trenches isn’t practical.
