Northwest Pipe Company's Permalok HDD Joint has received the prestigious 2025 Abbott Innovation Award from the North American Society for Trenchless Technology (NASTT). The award was presented at the 2025 No-Dig Show in Denver, recognizing groundbreaking innovations in trenchless technology.
The Permalok HDD Joint is a direct-push steel casing system engineered to optimize Horizontal Directional Drilling (HDD) operations. Its weld-free, press-fit joint design eliminates the need for pipe string-out and welding on the exit side, which significantly reduces the overall footprint, accelerates installation, and lowers construction costs.
This innovative system has already demonstrated real-world impact, notably in the Champlain Hudson Power Express (CHPE) project, where it enabled installation in a dense urban environment that traditional HDD methods could not accommodate. The award underscores Northwest Pipe Company's commitment to developing high-performance solutions for complex infrastructure challenges.
