NWPX Infrastructure's Innovative Leap in Microtunneling

NWPX Infrastructure, Inc., renowned for its advancements in water-related infrastructure products, has made a groundbreaking stride with the successful installation of its patent-pending Permalok® Radial Bending Joint technology. This innovative solution redefines the possibilities in trenchless infrastructure construction by allowing for steel casing pipes to be laid out in intentionally curved alignments. This marks a significant shift in how microtunneling projects are approached, particularly in densely populated areas.

A Landmark Installation

On June 10, 2026, the company announced that it had completed the first successful field installation of this revolutionary technology in Pleasure Bay, New Jersey. This specific installation utilized a 72-inch outer diameter casing pipe, achieving a 5,500-foot-radius curve, demonstrating its flexibility in navigating the complexities of urban infrastructure.

The Radial Bending Joint system not only allows for curved installations but does so while retaining the integrity of the pipe and eliminating the need for welding. This feature significantly reduces field labor requirements and is compatible with traditional microtunneling boring machines and jacking systems. Prior to this technology, engineers had to design their projects around existing underground obstacles, which often led to challenges and increased costs.

Advantages of the Radial Bending Joint

Scott Montross, President and CEO of NWPX Infrastructure, expressed his enthusiasm about the impact of this technology on the industry. He highlighted that the successful application of the Radial Bending Joint signifies that curved steel microtunneling is not merely a concept but a tangible reality, enabling previously unfeasible infrastructure projects to become possible.

In total, approximately 1,290 linear feet of casing pipe were installed as part of an urgent wastewater infrastructure project for the Two Rivers Water Reclamation Authority. This project was designed by Hazen and Sawyer, and the installation was executed by Northeast Remsco Construction. This innovative approach provided a critical solution in completing a wastewater conveyance project that had been stalled due to construction challenges.

Impact on Future Infrastructure Projects

The introduction of the Radial Bending Joint technology by NWPX marks a pivotal addition to the trenchless infrastructure space. It opens new avenues for engineers and construction teams who face the task of integrating modern infrastructure solutions within the existing urban fabric. This advancement can potentially lessen the environmental impact by reducing the need for extensive surface disruption. By minimizing excavation, the new technology can lead to smoother project timelines and reduced costs.

NWPX Infrastructure has reaffirmed its position as a leader in innovation within the industry with this milestone. The company emphasizes its commitment to developing solutions that meet the growing demand for improved water management infrastructure across North America.
