PierTech Systems is excited to announce the receipt of ESR-3969 from the ICC Evaluation Service, LLC (ICC-ES), on the company’s new and improved 2-7/8” helical pile system. This product is in compliance with AC358 and provisions of 2015, 2012, and 2009 International Building Code (IBC).  ESR-3969, includes the newly patented Cross Lock Connection on all lead and extension sections, new construction bracket, and the patented Tru-Lift Bracket for underpinning existing foundations.

“At Piertech we take pride in providing excellent customer service and innovative products.  After years of watching contractors struggle with hole elongation and lost time making pile connections, we set out to design a superior product that would eliminate these issues. The Cross Lock Connection is the solution. Customers using this product tell us they save up to 50% on their installation time.” says Kevin Kaufman, President of PierTech Systems.

PierTech’s patented Cross Lock Connection boasts some major improvements on the conventional pipe sleeve coupler:


  • Instant alignment
  • Complete steel on steel connection
  • Torque is fully contained in the coupling
  • Zero bolt hole elongation during installation

PierTech Engineer Michael Wilkis talked about their company’s accomplishment. “We understand the importance of having independently accredited products for our customers. Our team has worked around the clock to have our new patented 2-7/8″ Cross Lock Connection System in compliance with the top building codes in the world, in time for the 2017 construction season.”

As the helical pile industry continues to grow each year, it is more important than ever for engineers and building officials to choose manufacturers who are committed to the level of quality control found in the AC358. This is evident when a manufacturer receives an ESR report on their product.
