What is the difference between gunite and concrete pools?

Concrete pools can be made of either shotcrete or gunite. The difference is when the concrete mixes with the water. Gunite is dry concrete mix that only mixes with water at the nozzle when it’s sprayed.

Is saltwater bad for gunite pools?

Saltwater chlorinators are perfectly safe for gunite pools. As far as concerns about the gunite surfacing experiencing corrosion or pitting because of the salt in the water, rest assured salt is no more damaging to the structure of concrete than chlorine.

What makes a gunite swimming pool so special?

Other critical elements go into building a gunite pool, including tile, plumbing, electric, and perimeter coping. However, what sets gunite construction apart from other types of pool is the gunite, steel, and plaster. And what sets the completed project apart is the incredible durability and design versatility that this trio provides.

What do you use gunite and shotcrete for?

Both gunite and shotcrete are used to build swimming pool shells—the rock-hard vessels that can withstand pressure from shifting soil and the weight of thousands of gallons of water. What’s shotcrete—and what’s the difference between it and gunite? What’s most important to understand here is that both gunite and shotcrete are a form of concrete.

What is the velocity of gunite shotcrete in a pool?

Complete compaction of the pool shell concrete is a direct result of the velocity (typically 65 to 115 ft/s [20 to 35 m/s]5 ) at which the mixture is shotcreted onto the substrate.

Can You Spray gunite on a vertical surface?

Because it is applied using a compressed air “gun,” builders can spray concrete on vertical surfaces or curves. In addition to being a popular choice for inground pool construction, gunite is also used widely in things like road tunnels.

What is the average lifespan of a gunite pool?

How long will a gunite pool last? If you build a genuine pool properly with proper materials, you can expect to last approximately 100 years. Some internal and external factors affect the lifespan of the gunite pool. So, after building a gunite pool, take proper maintenance. How often do you have to Replaster a gunite pool? Once in every 10 years.

What is the difference between concrete and gunite?

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.

Is gunite stronger than concrete?

Gunite will result in even stronger concrete than shotcrete . If constructed or designed incorrectly, any form of concrete work, including all three methods, will be disastrous. It is imperative that the pool contractor hired for the concrete work be highly experienced with the chosen method of concrete construction.

What are gunite specs?

Gunite General Specifications DEFINITION Gunite as herein specified is a trade name used to designate a mixture of Portland cement and sand thoroughly mixed dry, passed through a cement gun and conveyed by air through a flexible tube, hydrated at a nozzle at the end of such flexible tube and deposited by air pressure in its place of final repose.
