Yes, helical piers can support structural loads comparable to traditional concrete foundations, though their specific capacities differ based on the application.
For typical residential projects, helical pier capacities generally range from 10 to 150 kips (or 50–200 kN) per pier. In comparison, traditional concrete footings typically support 150–500 kN per support point.
While concrete foundations may offer higher absolute bearing capacities in stable soil, helical piers provide several distinct advantages:
- Performance in Challenging Soils: Helical piers are often superior in expansive clay, loose sand, or areas with high water tables because they extend deep into stable soil strata.
- Real-Time Verification: Unlike concrete, which requires curing time and quality control tests, the load capacity of a helical pier is verified in real-time during installation using torque monitoring.
- Efficiency and Cost: Helical piers typically cost 30% to 50% less than concrete foundations ($1,500–$3,000 vs. $2,500–$5,000 per point) and do not require the 3–7 day curing period associated with concrete.
Ultimately, a structural engineer determines the required capacity by integrating soil reports and building codes to ensure the chosen system safely supports the structure’s lifespan.
