Shotcrete and Grout solutions Shotcrete is mortar, or high-performance concrete conveyed through a hose and pneumatically projected at high velocity onto a backing surface. It is the force of this spraying action that leads to compaction of the concrete or mortar which then forms layers of concrete to the required thickness. Shotcreting has proved to be the best method for the construction of curved surfaces. Tunnel linings and domes are now much easier to construct with the advent of shotcrete technology.
