WHAT IS GUNITE?
Gunite is made of sand, water, and cement. It’s similar to concrete, with one important exception. Traditional concrete is poured section by section into wooden frames. However, gunite is applied in layers using a specialized spray gun. (Hence the name gunite.) Water is added to the dry concrete mix at the gun-shaped nozzle opening. The concrete is made in the air right before hitting the target. Pool professionals would say that gunite is a “dry mix” because the water is added to the material to form concrete onsite.
WHAT IS SHOTCRETE?
Shotcrete is also made of sand, water and cement. Like gunite, shotcrete is sprayed into place. Shotcrete is considered a “wet mix” because the water and dry mix are prepared prior to arrival. The premixed cement is shot out of a nozzle to form the pool.
WHAT IS THE DIFFERENCE BETWEEN GUNITE AND SHOTCRETE?
Structurally these two materials are very similar. The biggest difference between the two materials is when water is introduced to the mix. With gunite, the water is added on site. With shotcrete, the water is added prior to arrival. These two mixing techniques each have their own advantages.
ADVANTAGES OF GUNITE
• Gunite pools are durable and last for decades • They can be custom-shaped to fit your outdoor living area of choice • Plaster finishes allow you to coordinate the pool with the exterior design of your home • Pool owners can choose from a wide variety of finish options, such as pebbles or glass
ADVANTAGES OF SHOTCRETE
•Shotcrete pools are made of concrete and other materials, which means they're more durable than traditional pools •They can be installed in any shape or size, and their design is customizable to fit your needs •Shotcrete pools are less expensive to maintain because there's no need for a filter system •The pool surface is smooth so it won't catch on your skin like sand does when you swim laps •You'll never have to worry about the kids tracking dirt into the house from outside again!
