  • Deep Excavations - Support Systems - DeepExcavation

    The term excavation support refers to an engineered solution designed to stabilize an excavation. An excavation support is generally required for excavations that exceed a depth of 6 ft, or excavations that are not sloped. Support for deep excavations (depth exceeding 10 to 14 ft ) refers to the additional bracing that is required to stabilize
