January, 2017

PierTech Systems, with headquarters in Chesterfield, MO (, recently announced the receipt of ESR-3969 from the International Code Council Evaluation Service (ICC-ES), for the company’s new and improved 2.875” (73mm) helical pile system and brackets. This product is in compliance with the newly revised ICC-ES Acceptance Criteria (AC358) and provisions of the 2015, 2012, and 2009 International Building Code (IBC).  ESR-3969 includes the newly patented Cross Lock Connection on all lead and extension sections, a new construction bracket, and the company’s 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 bolt 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 including:

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

PierTech engineer, Michael Wilkis, commented about the 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 2.875” Cross Lock Connection System in compliance with the top building codes in the world and 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 manufacture’s products with confidence knowing they are in compliance with AC358.  PierTech Systems is proud to now offer products with this important designation.
