Sprayed Concrete

Sprayed concrete is also called as gunite or shotcrete is used for rapid concrete construction. This method is used for repair of damaged buildings, underground construction such as storage reservoir, tunnel linings as well as for new constructions. The method of sprayed concrete makes use of man, machine, and the concrete. This is a high - performance material, where the person who is assigned as the nozzle man for this purpose must gain great skill and dedication in the application.
