Helical piles, also known as helical piers, are deep foundation underpinning elements constructed using steel shafts with helical flights. The shafts are advanced to bearing depth by twisting them into the soil while monitoring torque to estimate the pile capacity.
Helical piles are one of the most common structural piling methods for residential foundation repair and new construction. An engineer will opt for helical piles when the soil conditions are known to have settlement problems, an installer will know how far to turn the piers to reach the desired depth/capacity by monitoring the installation torque.
Helical piles can be used for commercial foundation repair and new construction. We use CHANCE Helical piles for both, which can achieve ultimate capacities up to 300,000 pounds for each pile.
For foundation repair there are various benefits as well. Helical piles do not excavate, or create spoils that need to be removed, and loads can be immediately applied. You can install them in any weather condition, as well as in limited access areas.
Helical Tieback Anchors are also an option for tension applications. Once the minimum depth is obtained, the capacity can be determined by reading the installation torque and correlating it to the holding capacity ratio. Capacities up to 200,000 pounds are obtainable for tiebacks. Tiebacks can be used for roadways, building-site preparation, and retaining walls.
Quick Installation Time
We understand that these types of projects can be time sensitive. Depending on depths and site access piles can be installed at rates as high as 15-30 piles a day.
Suitable for Limited Access Area
Since our deep foundation support solutions are minimally invasive, they are also suitable for limited access areas.
LEED stands for Leadership in Energy and Environmental Design. Being LEED certified means our projects are resource efficient.
