Shotcreting is a method of placing concrete – when properly executed the final product is equivalent or superior to formed concrete. No special design considerations are required – CSA 23.3 and 23.4 apply to shotcrete works.
Shotcrete mix designs can be proportioned to meet specified performance requirements including chloride, sulphate, and freeze/thaw resistance.
As with any type of concrete placement, qualified installers, material suppliers, and quality control practices are required to ensure the overall quality of the shotcrete.
