Tiebacks provide additional lateral resistance for various temporary and permanent support systems and to existing failing walls. They are constructed by drilling a hole and placing high strength steel bars or strand anchors in the hole that is grouted. Typically, tiebacks are used in conjunction with other retaining elements such as soldier or sheet piles. In many ways, a tieback is similar to a soil nail in that it is comprised of a steel tensile element and grout. However, there are quite a few differences, such as the fact that tiebacks are typically pre-loaded, which makes them an active element (whereas soil nails are passive elements).
Tiebacks can also be used to repair block retaining walls, wing walls/bridge abutments, or really any structure that needs additional capacity to resist the driving forces on the wall.
