CHANCE® Helical Piles provide the performance of concrete without the high mobilization costs and liabilities of driven or auger-cast piles and drilled shafts.
This time-saving and cost-effective deep foundation solution utilizes instant torque-to-capacity feedback as a built-in means of quality control, providing quality throughout the project. Helical Piles are designed, tested, and proven economical solutions for applications in expansive soils, high water tables, fill areas, and other sites where unstable soils require specialized support.

The Helical Pulldown™ Micropile brings the advantages of the pre-engineered helical system to the heavy micropile and anchoring markets providing tension loads of 70,000 lbs to 200,000 lbs and compression loads of 20,000 to 400,000 lbs. The pulldown micropile is a time efficient high capacity pile system that is constructed by reinforcing the helical pile shaft with a grout column. The addition of a high density grout column provides increased resistance to buckling in weak sub-surface soils while protecting the helical pile against corrosion in aggressive soils. By combining the skin friction of the grout column with the end-bearing helical piles, load capacities can be substantially increased.
