Pezzimenti Tunnelbore specialises in microtunnelling – the drilling of highly accurate, laser-guided bores ranging in diameter from 325mm to 3000mm in ground ranging from sandy clay to basalt in lengths up to and beyond 300m. Microtunnelling has become an integral part of installing gravity flow sewers and stormwater in urban areas.

Innovation In-House

Pezzimenti Tunnelbore Innovation in-House

All equipment used by Pezzimenti Tunnelbore is designed and manufactured in the Melbourne Workshop, giving the flexibility to design machinery to achieve project-specific solutions.

Unsurpassed Experience

Pezzimenti Tunnelbore Unsurpassed Experience

Since inventing vacuum spoil extraction in 1986, the Pezzimenti Microtunnelling System has completed more than three times the number of bores of any other alternative in Australia.

Environmentally Safe

Pezzimenti Tunnelbore Microtunnelling Environmentally Friendly

Unlike other pipe installation techniques, our system leaves the surface undisturbed. Critical surface areas including areas of Aboriginal significance and natural water courses all remain untouched, ensuring the protection and preservation of their value.

Microtunnelling Ground Left


Detatchable cutters and a modular system means Pezzimenti can operate in very soft to very hard rock

Microtunnelling Length


Single drives up to 260m and lengths up to 440m, using intercept bore method.

Microtunnelling Diameter


The system that can microtunnel diameters ranging from 300mm up to 3000mm.

Microtunnelling Pipes


Any pipe that is available in the Australian market can be installed with this system.

Microtunnelling Accuracy


The laser guided system achieves as standard: +/-10mm at distances up to 150m and +/-40mm at 200m.

Microtunnelling Equipment


The modular system means we can achieve setup in very tight or expansive sites.

Feature Project – Wyee

Pezzimenti Microtunnelling Feature Project Wyee

Pezzimenti completed two simultaneous Rail Crossings at Wyee on the NSW Central Coast during one 48 hour weekend shutdown. Retractable heads were used on both bores.
