The application of the mortar consisting of water, aggregate, cement and optionally admixture mixture with compressed air on a tapered or perpendicular surface.

Spraying is a robust and durable construction material which is prepared in accordance with the standards of concrete and exhibits a better adherence than other materials if applied. There are two different types of sprayed concrete: dry mix and wet mix.
In the dry mixture process, all the ingredients in the mixture are mixed without adding water, and then water is added while dispensing by air pressure from the end of the mixture hose. In the wet mixing method, all materials in the mixture are combined with water and the mixture is sprayed on the surface with wet pressure.
