Helical Tieback Anchors

Better tieback walls with CHANCE® Helical Tieback Anchors

What are Helical Tieback Anchors?

Helical Tieback Anchors are a pre-engineered tieback system for earth retention. Engineered by the largest manufacturer of anchors in the world, tieback anchors simplify the challenges for contractors.
The success of the screw anchor tieback system is based on decades of similar use of CHANCE anchors by electric utilities. The proven reliability and engineered predictability of the system’s performance give you tiebacks that are positive, economical and hassle-free.
  • Installed anchors can be proof-tested immediately – no waiting for grout to cure.
  • Install in almost any weather, with conventional drilling equipment. No concrete trucks or grout pumps required.
  • Predictable holding strength in all soils.

How Tieback Anchors Are Installed

These tieback anchors are installed by rotating the anchors into the ground with common rotary drilling equipment.
Once the minimum depth is obtained the capacity can be determined by reading the installing torque and correlating it to the holding capacity ratio. Capacities to 200,000 pounds per anchor are obtainable with this system. Proven on hundreds of applications these cost effective tiebacks can be tested immediately. No concrete to wait for curing! This saves time and money plus improves schedules.
