Gunite is a specific term referring to dry concrete applied using pressurised air, where mixing with water occurs at the nozzle, as it is applied. The Gunite technique allows a skilled worker to add precisely the correct amount of water to obtain the required viscosity for application to both vertical or horizontal surfaces (overhead), and so it can develop the required strength for the final product.

Gunite is used to reinforce both temporary and permanent excavations. This provides a large waterproof enclosure in which a structure can be erected. Once the structure is completed the area between its foundation and the Gunite is back filled and compacted.

Gunite is also a viable means and method for placing structural concrete.

In-ground swimming pools can use either the wet or dry application method.
