How it works

Installation

Length adjustment

Piles are typically installed using conventional tracked or wheeled excavators equipped with a torque motor attachment. This attachment measures the torque applied during installation to ensure compliance with the design specifications.

Helical Piles are driven into the designated bearing stratum by rotating the steel shafts, a process facilitated by the torque motor connected to the excavator or rig.

Steel sections are joined using bolted connections, with additional sections added as needed to reach the required pile depth.
Strategically positioned helical flights along the shaft allow the pile to penetrate the soil without augering or displacing it, while torque is continuously monitored during installation. To verify compliance with design requirements, the final torque measurement is recorded over the last meter of advancement before the pile is set at the specified datum level.

Compliance and Approval

Executed DOT approved projects

Executed Federal Contract projects

Executed FAA construction projects

ISO 9000-Certified Manufacturing

From the first pile to the millionth, every CNT Geotechnical product meets the same exacting standards—guaranteeing uniform performance and reliability on every project.

ICC-ESR Certified

CNT Geotechnical products are backed by an ICC-ESR report, the industry-standard verification that our manufacturing process consistently meets code requirements. This certification ensures that the products we deliver are identical in quality and performance to those submitted for independent testing—giving you confidence in every pile we install.

IBC-Compliant Deep Foundation Systems

All CNT Geotechnical deep foundation elements are fully compliant with the International Building Code (IBC). With CNT, you're building on a foundation that’s not just strong—it’s code-approved and legally sound.

Used for underpinning existing foundations, supporting modular buildings, and reinforcing rail infrastructure.

Lightweight & Temporary Structures

Perfect for walkways, fencing, seating stands, and other structures where speed and mobility matter.

Sacrificial Pile Testing

Precision Starts Below the Surface

At CNT Geotechnical, every project begins with a sacrificial pile test—a critical step in evaluating soil conditions and fine-tuning our designs. This process ensures that each helical pile system is calibrated for maximum performance, reliability, and safety.

With in-house engineering, certified materials, and American-made components, we deliver foundation solutions that not only meet but exceed project requirements from the ground up.
