Shotcrete is the generic name for cement, sand and aggregate concretes which are applied pneumatically and compacted dynamically under high velocity.

In very poor-quality loose rock masses, where adhesion of the shotcrete to the rock surface is poor, the mesh provides a significant amount of reinforcement, even without shotcrete.
