To help the utility sector deliver its huge pipeline of work over the next decade, Edge Underground has expanded its national footprint.
Edge Underground, a leader in trenchless technology and microtunnelling, is expanding its footprint across Australia with the opening of a new base in Adelaide.
With existing bases in Melbourne, Sydney, Gold Coast and Townsville, Edge Underground –alongside its parent company, OptionX Group – has built a reputation for delivering innovative, reliable and cost-effective trenchless solutions. The new South Australian base marks another milestone in the company’s growth, helping it better serve clients across the country.
OptionX Group CEO, Stuart Harrison, said this move reflects Edge Underground’s overall growth strategy and strengthens its ability to provide industry-leading solutions to more clients nationwide, ensuring faster response times and greater project efficiency.
“Expanding to South Australia just made sense – it’s a natural progression that allows us to grow Edge Underground while staying close to the needs of our clients,” Mr Harrison said.
“At the same time, our commitment to supporting the growth of microtunnelling across Australia reflects our belief in smarter, less disruptive infrastructure delivery. We know our technologies have the potential to help shift markets away from traditional open trenching and toward more advanced trenchless solutions.”
Driving trenchless innovation
Edge Underground has long been at the forefront of trenchless innovation, and it even played a pivotal role in the development of the AdaptX microtunnelling system.
This groundbreaking technology, designed by Mr Harrison, has redefined efficiency in the industry by adapting to all ground conditions – including hard rock – without compromising accuracy or requiring costly machine modifications.
Edge Underground recently deployed this AdaptX system in a key Tasmanian project, demonstrating the growing demand for this technology across the country and reinforcing the company’s ability to support projects in diverse environments. Edge Underground has also been instrumental in the research and development of Riteline, a revolutionary casing spacer system.
Riteline ensures secure pipe installations and enhances performance in trenchless projects, setting a new standard for accuracy, versatility and ease of use. The system is height-adjustable from 30mm to 125mm, comes in Flex and Rigid Series options, and features adhesive backing to eliminate slippage during installation. It is already trusted by major Australian water authorities, with more than 100,000 units installed nationwide.
Proven success
Edge Underground said its reputation has been built by tackling jobs that others deem too difficult. With a long history of record-breaking microtunnelling projects, the company has successfully completed work in both major cities and remote locations, often tackling hard rock, mixed groundwater levels and other extreme conditions.
Among Edge Underground’s most notable projects was a job that involved installing critical infrastructure in challenging rocky terrain. By leveraging a combination of AdaptX technology and expert project management, Edge Underground was able to complete the work on time and within budget – despite conditions that would have caused significant delays for traditional methods.
With its new South Australian base, Edge Underground continues to build on its momentum, offering greater support for projects across the country and reinforcing its presence as a national leader in microtunnelling and trenchless technology.
Whether it’s high-performance trenchless installations or advanced innovations like AdaptX and Riteline, Edge Underground remains a trusted partner for delivering efficient, accurate and cost-effective solutions. U
