In the gunite swimming pool, a rebar framework is sprayed with a concrete and sand mixtures, creating a shorter construction time and less variability.

Built to last. One of the best reasons that there is a more and more constructed gunite pool is its durability. Gunite can provide enduring pool stability, it has a steel-reinforced concrete structure that holds water and stands the test of time. The key for its durable performance is its tensile strength or its ability to endure external force until it is compromised. Flexibility is another feature makes gunite perform even better in a swimming pool. It contracts and expands from factors like compaction, freezing, water intrusion and softening or even of dry conditions. The structure is tough and solid that can move and expand without cracking.

Installing a Gunite Swimming Pool

Gunite is really dependable in structural strength. It is a dry concrete made of sand and cement that is applied through a high-pressure hose mix with water. When it dries or cures, gunite becomes a hard-forming, thick rock, solid structure. Gunite produces flowing lines, various contours, depths, size and shapes forming a cohesive and visually appealing structure.

Installation of your new pool begins with the digging of your pool shape and the installation of the iron rebar. The rebar is carefully placed at specific intervals and this framework creates a grid around the perimeter of your pool to reinforce the structure. Extra steel goes into areas requiring an additional level of reinforcement. The cage is suspended several inches in the air so it does not touch the soil underneath it and that space remains to be filled in by gunite materials. Then the pool builders spray the heavy coating of gunite around the rebar at high velocity, creating a dense pool wall and floor. The gunite is then smoothed and wait to cure or dry to set. 

Once set, your pool finish will be applied based on your preferred design. Plaster, composed of cement and marble dust, is the most common finishing with its wide range of color options to match your pool surroundings. The plaster actually waterproofs a gunite swimming pool and gleams the pool interior surface. Another option for finishing is having a pebbled or tiled finish for a high-end and unique look. You can also add you are natural look amenities to improve the pool aesthetic. 

Shotcrete vs Gunite: What’s the Difference?

Many of the homeowners are confused with the difference between a gunite pool and shotcrete. Others think gunite and shotcrete are just regular concrete. Technically speaking, concrete is a mix of sand, cement, some aggregates, and water. While the term shotcrete generally refers to either wet or dry mix concrete that is applied through a hose, so gunite is just a variation of shotcrete. 

In the swimming pool industry, we take a different story in using these terminologies. Gunite and shotcrete are both types of concrete. The only difference between them is the preparation of the materials with water and the placement method for pneumatically placing concrete materials at high velocity. Gunite is concretely applied with the dry-mix process, the water is applied at the nozzle of the high-velocity hose when the builders applied it. Shotcrete is the wet mix of concrete. The mixture of cement, sand, and aggregates are already mixed with water when it delivers into your backyard and ready to be applied using the concrete sprayer. 

Let discuss a more detailed gunite pool building to see its difference with shotcrete. The gunite truck will deliver the dry load of sand and cement to your backyard. Then, the materials will pour into a container called a hopper. The hopper feeds the dry concrete into the mixing system or the auger. The auger feeds the gunite mix into a high-velocity hose. Using an additional separate tip and line which is connected to the gunite hose, it adds the water to the dry mix as its exit s the hose. Now the dry mix is blended with water and it is ready to be applied to your pool construction.

It is time to focus on shotcrete. It is a combination of cement, sand, aggregates, and water is already mixed. This material is ready to use as soon the delivery arrives at your backyard. Same with gunite, a high-pressure hose is needed to spray into the pool hole to create a durable structure. 

Either the two ways of spraying concrete materials, gunite and shotcrete are both homeowners’ top choice for swimming pool construction. Both are ideal in creating a solid structure with supreme durability and quality pool design. 

Gunite Swimming Pool Maintenance

  • Regular inspection for a leak in filters and pumps to minimize the chances of the possible leak if you usually use the pool. 
  • Maintain the water level to make sure to rebalance the chemicals and keep the filters freely clean your pool.

Like every other pool type, a gunite swimming pool has some downside in the pool construction process. The gunite process requires a skilled operator or the nozzleman that is in-charge in the sand, cement and water ratio. An error in the mixture can ruin the quality of the concrete. You should also avoid clogged dry mixture in the hose pipe. Gunite produces a lot of over-spray or rebound materials that making a mess in construction. You can reuse it to prevent converting it as just a waste.
