Earth and rock excavations are effectively stabilized with shotcrete and a variety of reinforcement and anchoring systems. Using shotcrete to stabilize soil for excavation has advantages over traditional timber and steel shoring techniques. Shotcrete is also ideal for ground support in tunneling and mining. It provides early ground support after blasting or excavating; early strength development, which provides flexibility to allow for ground stabilization and stress relief; and offers the ability to conform to the natural irregular profile of the ground without formwork, which makes it ideal for any tunnel. It is also the preferred material/process for underground stations, side drifts, shops, and provides long-term stability. It can be used as a final or permanent lining for underground structures.
