Large Diameter Helical Piles

Pileworks® Large-Diameter Helical Piles are high-capacity steel foundation systems built for utility-scale, energy, industrial, and heavy commercial work. Available through Foundation Technologies, Pileworks® gives contractors and engineers a fast, cleaner alternative to traditional deep foundation methods where speed, capacity, and jobsite control matter.

Large-Diameter Helical Foundations. Backed by FTI Support.

Pileworks® manufactures high-capacity helical piles and pile components for demanding foundation applications. Through FTI, contractors get access to product sourcing, engineering coordination, quoting support, delivery planning, and jobsite guidance—all from a team that understands deep foundation work.

Built for Energy, Utility, and Heavy Civil Projects

Pileworks® Large-Diameter Helical Piles are designed for projects that need more than a standard small-diameter helical solution, with applications across solar, transmission, industrial, and utility infrastructure.

Key Applications

• Utility-scale solar farms
• Transmission towers and high-voltage infrastructure
• Substations and electrical infrastructure
• Industrial foundations
• Heavy commercial foundations
• Pipeline supports and energy-sector infrastructure
• Temporary shoring and load testing applications
• Remote, restricted-access, or schedule-sensitive sites

Why Use Large-Diameter Helical Piles?

• Fast installation compared with many traditional deep foundation options
• Immediate load capability after installation
• Reduced spoils and cleaner jobsites
• Lower vibration and noise than driven pile methods
• Useful for remote sites, utility corridors, and energy infrastructure
• Manufactured steel components with traceability and quality control
• Engineering support available for project-specific requirements

Made in America, Meets BABA Requirements

Domestic manufacturing you can count on. Pileworks® products are produced in the United States using domestically sourced steel in alignment with Build America, Buy America (BABA) provisions. Manufacturing is supported by ISO-certified quality management systems, providing documented control over materials, fabrication, and final product performance.

Pileworks®  Helical Piles Sizes and Applications

*Final pile configuration, capacity, shaft size, helix design, and installation requirements should be reviewed for each project by a qualified engineer.

How Helical Piles Compare to Traditional Options

Large-diameter helical piles are a strong fit when a project is being evaluated against micropiles, augercast piles, driven piles, drilled shafts, or other deep foundation systems. Helical installation can reduce spoils, limit vibration, support faster production, and provide useful installation feedback through torque monitoring. 

Engineering and Project Support

FTI helps contractors and engineers evaluate whether Pileworks® is the right fit for a project. Our team can assist with early product selection, quote development, technical coordination, and next-step planning so projects move from concept to installation with fewer delays.

Common Project Questions

What diameter range is currently available?

FTI has partnered with Pileworks® to distribute helical piles of 5.5" to 24" diameter; Large-Diameter Helical Piles are custom-made to project specifications.

What kinds of projects are a fit?

Large diameter helical piles are especially relevant for solar farms, transmission structures, substations, industrial foundations, pipeline supports, energy infrastructure, and heavy commercial foundation work.

Can Pileworks® helical piles replace micropiles or augercast piles?

In some cases, yes. Large-diameter helical piles may be considered as an alternative when the project needs fast installation, reduced spoils, lower vibration, and immediate load capability. Suitability depends on site conditions, design requirements, and engineering review.

Is engineering review required?

Yes. Large-diameter helical pile projects should be reviewed by a qualified engineer. Final recommendations depend on soil conditions, structural loads, installation criteria, and project-specific requirements.
