Development of Design Recommendations for Helical Pile Anchorages Subjected to Cyclic Load Reversals.


Helical Pile Design Training Course

Based on DFI’s Helical Design Guide, this course covers design recommendations, installation and specifications of helical elements.

Initiative currently in progress…

Helical Tradeshow

Showcases high-quality, safe, reliable and cost-effective foundation solutions using helical piles and tiebacks. Structured technical education program, including indoor and outdoor equipment exhibitions, and live installation demonstrations.

Industry Outreach

Young Professionals

Educating the next generations of design professionals about helical deep foundation products. Reach out to a committee member or a DFI representative today to get plugged in to our current young professional or student activity.


As we inform the deep foundation industry on the benefits of the use of helical products, one of the most important partners in this effort are the trade contractors who use the products every day. Our committee is constantly seeking new ways get our contractors involved. For more information on how to join our committee reach out to a committee member or DFI today.
