Tieback Retention
If the depth of excavation near the retention is anticipated to exceed about 15 vertical feet, it is usually cost-effective to use ground anchors or structural bracing to minimize the required strength (and cost) of the piling elements used in the retention design. Tiebacks can be installed to add additional capacity to a variety of earth retention systems, instead of a cantilevered wall. Tiebacks are drilled horizontally at an angle and consist of a grouted steel element that is stressed and locked-off at design load.
