With “wet-process shotcrete,” a low-slump concrete mix is pumped to the pipeline’s end, where a special “shotcrete nozzle” is attached, using a Concrete Pump. The compressed air introduced by the shotcrete nozzle is injected into the concrete. This compressed air is typically supplied by a 165-185cfm air compressor, which is available separately. The compressed air gives the concrete more velocity, causing it to spray out of the nozzle. The low slump of the shotcrete mix, combined with the high velocity, allows the concrete to be sprayed on cliffs, vertical walls, and overhead.
Any wall thickness and concrete finish can be shotcreted. Basement and parking garage walls are two examples of typical applications. Shotcrete has no limits. Design your custom creation without the constraints of cast-in-place concrete’s constructability and expense. Shotcrete contractor for pools and aquatics that is dependable and of high quality.

A high-quality construction guarantees that your pool can last as long as possible. Shotcrete may be spread horizontally, vertically, or even upward to adhere and shape to the underside of a ceiling since it is a free form of concrete. This results in extremely strong and watertight structures that can be shaped into any shape. Using a pump, hose, and a specially built application nozzle, shotcrete is applied pneumatically. In a shotcrete application, the cement content is higher and the water content is lower than in a “cast-in-place” application. The mixture produces a dry concrete mix suitable for use on vertical surfaces such as pool walls.
Aside from the obvious construction benefits mentioned below, shortcreting gives the builder and designer more versatility and design imagination.
Shotcrete pools are the best and most watertight when correctly built and installed. As compared to other alternatives such as block-filled walls or reinforced concrete, shotcrete is ideal for extremely fast construction. Since the concrete mixture contains less water, there is less volume change as a result of water hydration, resulting in much less joints in the pool between wall parts than for a cast-in-place wall.
- Higher compressive strengths than cast-in-place concrete, ranging from 6,000 to 7,000 psi.
- Any shape or design can be made strong and watertight using the free form application.
The consistency, strength, and integrity of construction materials are ensured by using wet concrete, which is mixed to exacting standards in a factory-controlled environment and trucked directly to the pool site.
And when using shotcrete for pool construction, the contractor must be highly skilled, as is the case for any construction. Shotcrete, when done correctly, produces a much better and watertight pool installation than cast-in-place.
