Helical Anchors, Inc. (HAI), www.helicalanchorsinc.com, with manufacturing and corporate offices located in Minneapolis, MN, recently supplied (20) 2.875” O.D. (73mm) with 0.217” wall (5.5mm) helical piles with 8”,10” helix bearing plates for strengthening a residential foundation in Portland, OR. In addition to the helical piles, (20) underpinning brackets were installed. Load testing was a requirement for the project, and the test piles were loaded to 200% of the required (40) kip design load. Both the piles and the brackets have been certified by ICC-ES as reported in ESR-3982.
HAI has the ability to to make larger diameter helical piles up to 12.75” O.D. (323.9 mm).
“We are the only helical pile manufacturer that inertia welds their piles,” said sales manager, Ryan Dungan. “This technology originated in the oil industry, and HAI is leading the industry using this technology to manufacture our helical piles. The science of inertia welding is simple, but doing it correctly time and time again is something that requires in-depth training and rigid quality control standards. By combining our high strength steel with this manufacturing technique, our piles can withstand higher torque capacities, which allows our clients to install smaller and less expensive piles, while at the same time achieving the capacities of our competitors’ larger diameter piles,” Dungan added.
