While helical piers are often more affordable for lighter loads, several factors can make them more expensive than push piers depending on the specific project requirements.

Key reasons why helical piers may involve a higher investment include:

• Manufacturing Complexity: Helical piers require a more complex fabrication process involving steel shafts with pre-welded helices. The precise welding and specialized corrosion-resistant galvanization required for these units increase the per-unit material cost compared to the standard steel tubing used for push piers.
• Pre-Unit Material Costs: According to industry data, helical piers typically have a higher cost range per linear foot ($180–$300) than push piers ($150–$250) due to their manufacturing requirements.
• Geological Requirements: In the Colorado Front Range, expansive clay and rocky terrain may necessitate the use of advanced, high-power torque motors to successfully drive helical piers into the ground, which can influence the installation budget.
• Customization: If site conditions require specialized features—such as larger shaft diameters or extra corrosion-resistant coatings—material costs can increase by 15-25%.

Ultimately, while helical piers save on excavation and heavy equipment costs, their higher manufacturing and material price points per unit often drive the total cost for specific site applications.
