What Are Tiebacks in Construction?

January 26, 2024

When it comes to building construction, there are countless techniques that help ensure the safety and longevity of the structures we build. One essential technique is tiebacks, which play a vital role in many construction projects, particularly in the case of retaining walls and excavation support. Read on to learn more about what are tiebacks in construction and how they can be utilized in your next project.

A tieback is a structural element installed in soil or rock to transfer applied tensile loads. These are typically in the form of a horizontal wire or rod, known as a "tieback tendon." The tieback is attached to the structure at one end and extends into the soil at an angle. The load is transferred through the tendon by tensioning, which can be achieved through a hydraulic jack or other specialized equipment. Depending on the application, the tieback may also be encased in grout or other protective coatings to prevent corrosion.

Tiebacks are commonly used in conjunction with sheet pile walls, secant and tangent walls and other forms of anchored retaining walls to enhance their stability. They can also be implemented in a number of other applications, including the reinforcement of buried structures and the stabilization of slopes.
