Manufactured in the U.S. with American materials and supplies, Cantsink helical piles are composed of a lead section with a helix and optional extension. The helical anchor is rotated like a screw through surface soils into more stable ground layers below with suitable soil bearing strata. Its corrugated helix provides greater strength compared to a standard flat plate steel helix.
Cantsink’s patented design includes a manufacturing process that merges the shaft and helix into a seamless pattern. This process produces less waste and produces stronger support. Tested and certified to the highest standards for performance, Cantsink helical piles have a yield strength of 36,000 psi and a minimal tensile strength of 58,000 psi. The solid bar, round corner square shaft has a 1.5” square diameter, and conforms to ASTM A576-90 with yield strength of 73,000 psi and tensile strength of 118,000.
Now providing helix sizes ranging from 8” to 19” in diameter, Cantsink products provide foundation support that can be quickly installed and customized through product selection to address specific site conditions.
