What is the term for using materials to support an excavation?

The term for using materials to support an excavation is shoring. This process involves the use of various materials, such as timber, steel, or other structural components, to provide temporary support to the walls of an excavation, preventing soil collapse and ensuring the safety of workers and equipment. Shoring is essential in construction and excavation projects where the stability of the surrounding earth might be compromised due to the removal of soil.

Bracing refers to a method used to provide additional support to a structure or to stabilize it against lateral forces, but it is often associated with supporting structures rather than excavations specifically. Retaining involves constructing walls or structures to hold back soil and prevent erosion or collapse, which is not the same as providing temporary support during excavation. Backfilling is the process of refilling an excavation with soil or other materials after construction work is completed.

Through shoring, excavators can safely create openings in the ground without the risk of soil cave-ins, which enhances worker safety and project efficiency.
