In new commercial construction, helical piers serve as a high-efficiency alternative to traditional deep foundations, specifically designed to address challenging soil conditions like expansive clays or loose fill. They are used to transfer structural loads to competent bearing strata deep underground, ensuring stability in environments prone to movement or freeze-thaw cycles.

Key ways helical piers are used in new commercial projects include:

• Foundations for New Structures: They provide primary structural support for commercial buildings, especially when soil reports indicate weak or variable subsurface conditions.
• Immediate Load Bearing: Because they require no concrete curing time, the piers can be loaded immediately after installation. This can accelerate construction schedules by up to 66% compared to traditional methods.
• Deep Foundation Stabilization: The piers are advanced into the ground using rotary equipment until they reach a bearing stratum, preserving the soil’s integrity with minimal disturbance.
• Lateral Support and Shoring: Helical piers are utilized as tiebacks and lateral anchors to resist soil pressure against excavation faces and retaining walls.
• Municipal Infrastructure: They are frequently used for public works projects like boardwalks and pedestrian bridges, where low site impact and speed are critical.

Throughout the process, installers use torque-to-capacity correlation to provide real-time verification of load capacity, ensuring the foundation meets rigorous ASTM and ASCE engineering standards.
