Every beginning is hard but as long as you are consistent with your learning, everything is possible which also applies with being a shotcrete operator.
To be a qualified shotcrete crew you must be consistent with the training as well as with your experience.
A shotcrete crew is compose of the foreman, nozzleman, assistant/trainee nozzleman, blowpipe control, wireman, rodman/ finisher, pump operator and the mixer man which each crew has its different roles.
The foreman should be able to supervise the team and should have a great experience minimum of two years.
The nozzle man should be certified and must be able to perform the different application, dry mix and wet mix.
The trainee should have an experience with being a different crew before it becomes a nozzle man assistant.
The blowpipe should be knowledgeable with the different finishes of the sprayed concrete. The wireman is responsible with the line or grade of the application.
The rodman/finisher should be able to make sure that the application is consistent free from bulging, loose concrete, sagging or unstable sprayed concrete.
The pump operator should be skilled with the preparation and mixing depending on the type of application.
Lastly, the mixer man should be able to perform the preparation and mixing of the different material with the right ratio and proportion before it is fed into the pump machine.
The shotcrete should be able to know the requirements laid down by the engineer or test panel. These rules should be followed:
(1) Proper cleaning of the surface before spraying
(2) Able to apply bonding coating before heavier shotcrete application
(3) Proper distance of the nozzle and the surface to achieve the right consistency and thickness of the shotcrete layer
(4) Lessen the bulging, air pockets, sagging and rebounds
(5) Lastly, clean the equipment immediately after application to prevent accumulation of the materials in the pump, hose and nozzle which will after the succeeding application.
