Helical piles are screwed into the soil, not driven or vibrated, nor is a hole dug or drilled. The soil around the pile remains undisturbed. Predictable holding capacity is achieved by monitoring installation torque of the pile during construction. Monitoring installation torque is similar to monitoring blow counts of driven piles for predicting pile capacity. A typical helical pile can be installed in minutes using standard equipment such as a pole line truck, excavator, backhoe, skid steer or picker truck. After installation, the load can be applied immediately - no additional work is required. Helical piles are ideal in areas of limited access, such as areas with low overhead or width restrictions. Installation is unaffected by weather or high water table. No vibration during installation means no damage to sensitive structures or instrumentation in the construction zone.
