FAQ
How is Shotcrete Applied?
Shotcrete is a method of applying concrete projected at high velocity through a nozzle primarily on to a vertical or overhead surface. The impact created by the application consolidates the concrete to the object it is applied to.
Shotcrete Vs. Cast-in-Place?
Although the hardened properties of shotcrete are similar to those of conventional cast-in-place concrete, the nature of the placement process results in an excellent bond with most substrates, and rapid or instant capabilities, particularly on complex forms or shapes. The shotcrete process requires less formwork and can be more economical than conventionally placed concrete.
Wet-mix Vs Dry-mix?
Shotcrete is applied using a wet- or dry-mix process. The wet-mix shotcrete process mixes all ingredients, including water, before introduction into the delivery hose. The dry-mix shotcrete process adds water to the mix at the nozzle. We primarily use a wet-mix system.
Is Ultimate Shotcrete and Steel Nozzleman-Certified?
Ultimate Shotcrete and Steel contractors are American Concrete Institute (ACI) certified shotcrete nozzleman. We carefully vet every contractor we hire to ensure they have the training and certification necessary to perform any residential or commercial shotcrete job.
What can shotcrete be used for?
Some of the most common applications for shotcrete include
- Ground Support
- Swimming Pools
- Skate Parks
- Refractory
- Domes
- Architecture & Landscaping
- Repair Work
- Restoration Work
What kind of finish can I use shotcrete for?
Shotcrete doesn’t simply produce a gun / nozzle finish. It can be finished in almost any class, type, and tolerance. A wood float and sponge finish, broom, steel trowel, and even simulated rock finishes are all attainable. Concrete finishes should be incorporated into the specification and performed and approved as part of a mock-up prior to the start of a project.
How long does shotcrete last?
The key to Shotcrete’s longevity is property care and maintenance. If you take care of the concrete surface, you can expect it to last more than 50 years.
How much waste does the shotcrete method create?
Every concrete application method results in a certain amount of waste. However, compared to gunite or cast-in-place applications, the amount of waste is much lower. Experts suggest that the waste generated by the shotcrete method is six to ten percent. By comparison, gunite waste is approximately 20 percent. The cast-in-place method can create up to 25 percent of waste.
Shotcrete waste consists of rebound and excess cutting/shaping of the plastic concrete. As long as shotcrete waste is within industry-accepted parameters, it is a part of the shotcrete process, not a detriment to it.

Can you apply shotcrete to existing concrete?
Yes. We often apply shotcrete to existing concrete structures to stabilize or reinforce the structure. Shotcrete is a practical and efficient means of prolonging the life of existing concrete structures. While it may not work in all situations, its flexibility and ease of application make it an attractive alternative to other means of rehabilitation.
Can you explain the shotcrete application process?
The shotcrete process requires less formwork and can be more economical than conventionally placed concrete. Shotcrete is applied using a wet- or dry-mix process. The wet-mix shotcrete process mixes all ingredients, including water, before introduction into the delivery hose. The dry-mix process adds water to the mix at the nozzle. We use shotcrete in new construction and repairs, and it is suitable for curved and thin elements.
Can shotcrete be used for different design options?
The choice of shotcrete over other traditional methods is growing day by day as many have known its benefits. One of the biggest benefits is that shotcrete is highly flexible. You can use it to design and create any shape. Best of all, it does not lose resiliency regardless of what design you have in mind.
