Shotcrete has often been described not as a material but as a process. Both wet and dry processes produce a material that exhibits superior hardened properties to high quality conventional concrete, such as high strength, low permeability and high durability.
Shotcrete – Wikipedia
Shotcrete’s high strength, durability, low permeability, excellent bond, and limitless shape possibilities can be achieved with either the wet or dry process, making it superior to high-quality conventional concrete. Both the wet and dry processes have been made almost interchangeable by advancements in material and equipment technology over …Author: Author/Paul-Bridger

Wet-mix shotcrete involves pumping of a previously prepared concrete, typically ready-mixed concrete, to the nozzle. Compressed air is introduced at the nozzle to impel the mixture onto the receiving surface. The wet-process procedure generally produces less rebound, waste (when material falls to the floor), and dust compared to the dry-mix …
