First they are all concrete, just different application methods. Gunite (dry nozzle)is a dry mix where water is added at the nozzle. Shotcrete (wet nozzle) is premixed wet. They both use high air pressure to force the mixture to stick to the wall. Just as if you take a ball of mud and throw it at something, if wants to stick.
Gunite bonds perfectly to prepared surfaces such as concrete, brick, rock, tile, stone or steel. Numerous tests have been made which indicate that the bond strength of Gunite exceeds the shearing strength of good quality brick or concrete against which it is applied. Gunite is heat resistant to a high degree and can be made more so by substituting refractory aggregates for part or all of the sand. Gunite is extremely strong, dense, and highly resistant to weathering and many forms of chemical attack.
