Gunnite, is the application of a dry monolithic refractory through a pressure system while water is injected into dry mix at the point application. The refractory is pumped into a hose by an air pressure system as a dry mix. It then mixes with water at the spray gun nozzle. This allows you to have full control over the water to mix ratio. A shotcrete, or a wet mix, refractory is a refractory material that is applied through an air pressure system after it has already been mixed with water. The shotcrete refractory is mixed with water until the desired consistency is present. The wet mix is then pumped to the nozzle gun and applied. WRC has been performing gunnite and shotcrete and have the best nozzle men in the industry which leads to there being less waste in turn saves the clients time and money.
