Is gunite the same as concrete?

You could refer to gunite as concrete’s cousin because they are both in the same family, but have their differences. Gunite is the dry mixed form of sprayed concrete. Gunite typically only contains fine particles in its mix while concrete contains both large and small particles.

What is better gunite or shotcrete?

Gunite generally lasts longer and maintains a higher quality than shotcrete. For instance, gunite tends to dry faster than shotcrete, leading to a much smoother surface and avoiding significant cracks from shrinking. Gunite can also withstand up to 9500 psi, a much higher psi than shotcrete.

Why is it called gunite?

For gunite, water is added to the dry concrete mix at the gun-shaped nozzle opening (hence the name “gunite”). The concrete is made in the air right before hitting its target. Shotcrete is different in that it is trucked to your property wet in a cement truck.

What is the life expectancy of a gunite pool?

A poorly built Gunite pool certainly has the potential to crack. But a properly built Gunite pool can and should last for 100 years or more, with no risk of cracking whatsoever.

Is a gunite pool worth it?

A Solid foundation: A gunite pool is perfect because of its amazing design versatility. These pools last the longest of all inground pools and often feature the best warranties. Gunite pools do not need wooden frameworks to hold the shape, so building is simpler than standard concrete.

Do gunite pools crack?

A common cause with pool cracks is from too-thin gunite used during the installation process. During the construction process, the gunite might not adhere properly to the steel framework. When this occurs, the gunite “rebounds,” or bounces back after application. Rebound gunite should be removed and thrown away.

Can I walk on gunite?

Gunite/shotcrete is applied much drier than poured concrete. You can literally walk on it with in a few hours of it being applied. The drier application also gives it much better compressive strength than poured concrete for otherwise the same mix.

Is gunite concrete waterproof?

The sealing of the pool is accomplished by the application of a water resistant lining to the shotcrete or gunite surface usually immediately prior to filling the pool. This water resistant lining is typically a plaster made with Portland Cement and special aggregates.

Can gunite get wet?

The gunite should be sprayed with water using your water hose and spray nozzle. Gunite will cure better and properly if kept moist. You can apply a light mist of water hours after the gunite application is completed. The next days you can apply a heavy spray to moisten the gunite.

Can gunite pools be salt water?

If you’re looking for a simple answer, the answer is yes. Saltwater chlorinators are perfectly safe for gunite pools. The biggest issues reported when using saltwater chlorinators with gunite pools have to do with the tendency of the plaster to stain over time when coming into contact with salt.
