When building a new home, short-term decisions usually include what floor tile to use in the kitchen or which coverings to put on the living room bay windows. Few homeowners think about which type of foundation offers the best long-term stability.
With residential remedial foundation repair becoming a greater concern, the CHANCE® helical pile was developed in the mid-1980s and was issued a helical underpinning methods patent in 1992. This all sounds well and good, but the question remains: Why are helical piles so effective for remedial foundation repair?

There is no equivalent for measuring torque directly in the tooling string. Using differential pressure (or pressure drop across the motor) can work if it is properly set up and calibrated, but keep in mind that pressure is being measured, not torque.

Capacity-to-torque relationships for helical piles are used frequently to determine termination criteria for helical piles. Empirical relationships between installation torque and capacity have been established for several helical pile shaft sizes, including square shaft and pipe shaft piles.
