Gunite

Gunite is a form of concrete and a method of its application. Originally it was a trademark, patented in North Carolina. The concrete is blasted by pneumatic pressure from a gun, hence "gun"-ite.

A dry mixture of sand and cement is blasted through a hose, with water added at the very end of the hose.

In common speech it started to refer to any type of spray-applied concrete, therefore this method is also called dry gun process, to distinguish it from the wet gun process, when fully pre-mixed, i.e., "wet" cement is being pumped. the latter method is also known as "shotcrete".

Both processes have their advantages and drawbacks. Recently it has become common to refer to both processes as "shotcrete".
