The installation depth is a primary driver of the total cost per helical pier because the relationship between depth and expense is directly proportional. As the depth increases, the cost rises due to several specific factors:
- Material Costs: Deeper installations require more raw materials, specifically additional steel for extension shafts to reach stable, load-bearing soil.
- Labor and Equipment: Reaching greater depths increases the time the installation crew spends on each pier. It also requires more hourly equipment runtime and may necessitate larger, more powerful hydraulic drive heads to handle increased torque.
- Incremental Pricing: For every extra foot of drilling beyond the baseline plan, costs can increase by an estimated $30–$50 per foot for each pier.
- Engineering Requirements: Installations exceeding 20 feet often require a more robust engineering assessment to verify capacity, which adds to the upfront project expenses.
Because soil conditions vary—even between neighboring lots—the depth required to reach competent bearing strata is unpredictable, making a professional site inspection essential for an accurate budget.
