Why you need to choose your gunite contractor carefully
The gunite process has its place, when used properly, but it also has its limitations, particularly if you’re dealing with an inexperienced contractor. Your best bet is to contact a contractor with the skill and experience to make the right calls, including:
- Which type of sprayed concrete fits your application best
- A nozzleman with the proper training and experience to execute your application. The gunite process can be tricky for an inexperienced nozzleman, because there is more opportunity for wasted material (higher cost) and a lower quality product if not mixed and applied properly.

What is gunite?
Gunite, similar to shotcrete, is a superior modern method of delivery for different types of concrete construction and applications. Originally invented by Carl Akeley, the gunite process involves shooting dry powered concrete through a hose, using compressed air. The primary difference for gunite vs. a shotcrete process is that water is added at application and can be controlled on the fly by a skilled nozzelman (the term used for a gunite hose operator).
This concrete construction/ application method allows for greater control, maneuverability and a wider range of applications than more traditional mold processing, and can be even more suitable than pre-mixed shotcrete for vertical or overhead applications.
Differences between gunite & shotcrete
Although sometimes used interchangeably, there is a difference between shotcrete and gunite. Not only is the timing of the water application different (shotcrete is mixed with water before application, while gunite is mixed during), but there are other differences as well. Shotcrete is mixed with concrete, water and some type of rock. Gunite, on the other hand, is a mixture of concrete and sand with water being added only at the time it is applied by the sprayer.
