Microtunnelling – pipe jacking – thrust boring – laser tunnel boring

Edge Underground are the experts when it comes to the trenchless installation of water and sewer pipelines in Australia. We utilise a range of installation methods to ensure every job is completed safely, efficiently and within budget.

Absolute precision microtunnelling


For microtunnelling installations, Edge Underground uses the Vermeer AXIS guided boring system, which was developed by company founder Stuart Harrison himself.
Back in 2002, Stuart was dissatisfied with the microtunnelling solutions available in the market, concerned that no product allowed for the optimum combination of high efficiency, productivity and pinpoint precision.
So Stuart began developing his own guided boring system: a versatile, pit-launched microtunneller, guided by laser to provide provide on-grade, pinpoint accuracy to within +/- 5mm. Stuart developed the machine so that he could change the head and cutter style or configuration to deal with changing ground conditions, making his microtunneller extremely versatile.
Stuart’s microtunneller made waves in the trenchless installation industry, and in 2006, Vermeer reached an agreement to acquire Stuart’s patented technology. Since then, Vermeer has worked with Stuart to further refine the Vermeer AXIS guided boring system and distribute it to wider markets.
Since it was first developed, the Vermeer AXIS guided boring system has been used to successfully install hundreds of thousands of metres of sewer and water pipelines under various ground conditions, providing operators with an efficient method of installation that offers pinpoint accuracy every time.
Edge Underground truly is Australia’s microtunnelling contractor of choice.
