The shotcrete process involves discharging either mortar or high-performance concrete out via a spray gun, usually onto a vertical or overhead surface. Using a compressor, the material is pneumatically shot out at high velocity in a spraying motion, and the force of the back -and-forth action leads to the material compacting to form a monolithic film of concrete.The speed at which the process operates and application’s flexibility makes shotcrete particularly attractive for the construction industry. It is the preferred method of stabilisation and aesthetics in the construction of tunnels, reinforcement of slopes, and projects where variable thicknesses or thin layers of concrete is required.
