Helical Tieback Anchors

Helical Tieback Anchors

CHANCE® helical tiebacks are a pre-engineered mechanical anchoring system for permanent and temporary earth retention. The success of the helical anchor tieback system dates back to decades of similar use of CHANCE® anchors in the electric utilities industry. Capacities up to 200,000 lbs per anchor are obtainable with this quick and cost-effective tieback system.

Helical Tieback Installation

Helical tieback anchors are installed into retained soil with commonly available hydraulic rotary drilling equipment. Once the minimum length is obtained the capacity is determined by reading the installation torque and correlating it to the holding capacity ratio of the soil strength. The tiebacks are then tensioned immediately and tested without the need of grout, curing time, or spoils cleanup - saving a tremendous amount of project time and cost.
