The leaders in Slurry Microtunnelling and Civil Works

GM Microtunneling is based in Western Australia, we have 40 years of experience in horizontal boring and the expertise you need for your next project.


Slurry Microtunnelling is a trenchless construction method used to install pipelines beneath buildings, highways, railroads, runways, rivers, and environmentally sensitive areas. This method is particularly suited to gravity sewer, water and drainage pipelines as the process is extremely precise with deviations from target less than +/- 10mm over 160m.

GM Microtunnelling owns and operates the latest in Microtunnelling Slurry Shield machines using the Iseki TCZ & TCS range.

We install pipe for a variety of applications including:

Sewerage pipelines
