tiebacks What Are Tiebacks? Tiebacks are steel bars equipped with an anchoring device drilled through the soil past its failure plane into unaffected soil that has the capacity, like rock, shale, etc, to withstand the desired load. Tiebacks are commonly used to help support and stabilize a foundation. Tiebacks are used in both temporary and permanent structures. Process of Tieback Construction The first step in using tiebacks is to drill the holes the desired depth and in the desired diameter. The steel bar is then placed into the hole, and an initial amount of grout is pumped into the hole to stabilize the steel bar. Testing should then be done to make sure that the steel bars will support the appropriate amount. Once testing is confirmed, more grout should be pumped into the hole to ensure proper stabilization.
