Helix-Piles are steel piles with a helical shear ring attached in the bearing zone to transfer structural loads to the subsoil via soil shear. These units support greater loads than similar size conventional piling, and with greater redundancy. Properly designed Helix-Piles requiire shorter embedment depths than conventional adfreeze piles. Flexibility of the helical shear ring allows for a uniform distribution of high transient loads along the pile shaft. Helix-Piles are typically used to support high loads and provide a high redundancy factor when the benefits of thermo-cycling are not required.
