Refusal or “Spin- out” of a helical pile occurs when the pile refuses to penetrate while continuing to rotate during installation. Spin-out can occur when the soil’s resistance to penetration exceeds the downward thrust generated by the helix plates and the crowd pressure applied by the 28,000# excavator. Spin-out usually occurs at the conversion between a dense soil layer and bedrock when the helix plates confront hard/very dense material. Helical pile spin-out (refusal) affects the load capacity, and the means to predict said capacity via torque correlation. Once the helical pile tip (3.5” Diameter) encounters lime rock, the installation torque can no longer be commuted. The digital torque indicator may only record as the helical pile is progressing and creating torque resistance. Therefore, the bearing capacity of spin-out piles can only be determined definitively with an actual static load test. When the helical pile has spun-out on bedrock, the capacity can be assumed to be limited to the structural strength of the bottom-most helix plate – assuming the bedrock is strong enough to bear the load.
