Shotcreting machine SSB 02 works on the rotor principle and it is designed for the processing of dry or wet mixtures. It is the most efficient model of the shotcreting machines (concrete spraying machines) series SSB and it is appropriate to execute works of medium and large scope. It is used, in particular, to reinforce surfaces of engineering structures and the construction of water works, to reinforce the vaulting of tunnels and collectors in underground engineering and to maintain concrete constructions.
