Shotcrete
Shotcrete (guniting) is a type of concrete that is spouted against surfaces. There are two methods. With the dry variant, the water is added only in the nozzle of the lance. The mixing does not take place until the shotcrete adheres to the surface.
With the wet method, the cement is mixed in advance with water and then led through the hose, whereby only air under high pressure is added. Shotcrete can be easily applied to previously installed reinforcement.
