Material hoses are items that are sometimes overlooked. Hoses should be checked on a daily basis for weak spots, loose fittings (dry-mix), excess wear on the outside of the hose, and hose clamps/gaskets (wet- and dry-mix). On dry-mix shotcrete jobs that have shooting on a daily basis without moving, you should check and rotate the hose. This will reduce excess wear on the inside of the hose if there are any bends in the hose. Even tying the hose off to scaffolding or a man lift will cause unusual wear on the inside of the hose. Wet-mix shotcrete hose needs to be looked at a couple of different ways. One should inspect the pressed-on ends daily.
