As trenchless innovation accelerates globally, contractors are being challenged to adapt quickly, investing in technology that expands capability, improves efficiency, and supports sustainable growth.
Remaining competitive now requires investment in equipment that strengthens both technical capacity and business resilience.
For Recore Pipe Relining Specialists, this has meant strategic investment in advanced equipment and premium materials to expand operational capacity, enhance quality control, and support the business as project scale and complexity increase.
Operating in an evolving market, Recore Pipe Relining Specialists has adopted the latest trenchless technology from Rausch Rehab, including the RRcure 1500 UV curing system – engineered to deliver controlled, verifiable curing outcomes in demanding environments – and the RRLQ Hybrid Manhole light source, which enables curing in vertical shafts and maintenance holes up to DN1800.
The business has also expanded its capability to undertake complex renewal projects with the Cosmic C120 robotic system.
This modular system enables mainline and lateral inspections, robotic cutting, and the installation of UV-cured tophat seals and short-form patches, allowing the team to deliver a broader range of trenchless solutions efficiently and accurately.
Together, these investments further cement Recore Pipe Relining Specialists as a key player in New Zealand’s trenchless market.
Based in Waikato, Recore Pipe Relining Specialists delivers innovative solutions to complex infrastructure projects on behalf of councils and construction partners across the Waikato and Bay of Plenty regions along with the wider New Zealand market.
Supported by Pipe Core with materials and equipment aligned to project requirements, the team recently completed the renewal of 76m of DN375 sewer main beneath a busy road in Huntly on behalf of Watercare NZ.
The project utilised SAERTEX-LINER® MULTI, a glass-reinforced liner engineered for long-term structural performance in gravity sewer applications and backed by a verified 100-year technical service life, paired with the Rausch RRcure 1500 for curing.
Access was achieved via manholes on either side of the road, with a seven-person crew split across upstream and downstream locations to maintain clear communication and efficient coordination throughout installation.
High-pressure water jetting was used to prepare the host pipe prior to liner installation. Given the pipe’s depth of approximately two metres and its role in servicing a growing catchment, installation quality and curing verification were critical.
“We’ve now completed over 800m of lining using the RRcure 1500, giving us confidence on this project. Curing has gone smoothly across all installations,” said Daryll Walker, General Manager at Recore Pipe Relining Specialists.
“The ability to monitor the liner throughout the curing process gives both us and our client confidence that the liner has been properly cured, particularly in deeper assets where visibility is limited.”
Traffic management was implemented for the duration of the works, with over-pumping managed using two vacuum trucks.
The crew was on-site for two days, with curing completed within a four-hour window before flows were safely reinstated. Efficiency onsite was essential to minimise disruption and manage costs associated with traffic control and bypass operations.
The project marked Recore Pipe Relining Specialists’ first engagement with Watercare NZ, who were impressed with both the outcome and the contractor’s demonstrated capability.
“Our client wanted a liner system that could clearly support a 100-year technical service life – something SAERTEX multiCom® could stand behind,” said Walker.
“In trenchless work, no two project conditions are the same, but the goal is always long-term asset performance,” said Sergej Fast, Technical Manager at Pipe Core.
Walker acknowledged the collaboration behind the project, noting the partnership approach taken with Pipe Core and SAERTEX multiCom to ensure the right technology was selected and the outcome was a success.
“It all went smoothly, and we can clearly see the benefits of our investments. We look forward to continuing this work in New Zealand backed by our technology partners,” Walker said.
