Excavation support refers to an engineered solution designed to stabilize an excavation.
Excavation support is generally required for excavations in excess of 6 ft or excavation that are not sloped. Excavation support for deep excavations refers to the additional bracing that is required to stabilize a retaining wall such as a sheet pile when excavation gets typically deeper than 10 to 14 ft
Such excavation support systems comprise tiebacks, cross-lot steel struts, helical anchors, and top-down concrete slabs.
The role of support systems is to provide lateral bracing for retaining walls.
