Strength in foundation systems is often defined by the specific forces a structure must resist. While helical piers are not universally “stronger” than concrete piles, they offer distinct mechanical advantages depending on the load requirements:
- Uplift and Lateral Resistance: Our helical pier systems excel in providing superior uplift resistance due to their helical plates, which anchor the structure firmly against wind, flood, or seismic forces. They also provide excellent lateral capacity when properly braced.
- Compressive Strength: Traditional concrete piles are primarily designed for high compressive action. However, unless they are heavily reinforced with steel, they can be vulnerable to tension loads that occur during natural disasters.
- Immediate Load Capacity: A significant advantage of our advanced earth anchoring systems is the ability to support loads immediately. Unlike concrete, which requires weeks of curing time and static load tests, we use real-time torque monitoring to confirm bearing capacity to ICC-ES AC358 standards during the installation itself.
- Durability: To ensure long-term performance in wet or chemically active soils, our piers are hot-dip galvanized for corrosion resistance, whereas concrete can be susceptible to sulfate attack, cracking, and freeze-thaw damage.
The choice between materials depends on your project-specific needs. We recommend consulting with our network of structural engineers to determine which solution best fits your site’s soil profile and structural demands.
