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.
