 Helical Anchors, Inc. (HAI),,  with manufacturing and corporate offices located in Minneapolis, MN, recently supplied (106) 4.50” O.D. (114.3mm) helical piles with 10”,12”,14” helix bearing plates for foundation support for a 30 ft. X 50 ft. one story addition and renovation to an existing building.  The piles were installed on the interior of the existing structure.  The project required axial compression service loads of 70 kips, axial tension loads of 2 kips and lateral load of 750 lbs. for each pile.  A safety factor of 2.0 was assumed to develop the piles ultimate capacity. All of the piles were installed to 16-20 ft. on a layer of bedrock

“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.
