Evolution specialises in dry spray shotcrete application, first introduced in the USA in 1907 where it remains commonly known as gunite. In the early 1950s, wet shotcrete was introduced.

Dry spray is pumped in its dry form by high pressure air and mixed at the nozzle with water. Dry spray nozzlemen require an extra level of knowledge and care as they control the quality of shotcrete mixed at the nozzle.
