The Ultimate Guide to Gunite Pools: Everything You Need to Know
When it comes to in-ground pools, most people are familiar with the traditional concrete and aggregate plaster mixtures. However, there’s another material that stands out for its strength and durability: gunite. Gunite pools are constructed by shooting dry material out of a hose nozzle and then adding liquid to it as it comes out. This unique process sets gunite pools apart from traditional concrete pools and offers a range of benefits, including customizability and a variety of finishes. In this comprehensive guide, we’ll explore everything you need to know about gunite pools, including their cost, installation process, pros and cons, and how they compare to other common pool materials.
What Is Gunite?
Gunite is the dry mix form of concrete that contains only fine particles. Unlike traditional concrete, gunite sprays out of a nozzle dry, and water is added at the end of a hose controlled by a nozzle man. This process allows for greater flexibility and customizability in the construction of gunite pools. The main difference between gunite and concrete is the size of the aggregate used – concrete has larger aggregate that cannot be sprayed through a hose like gunite.
How Gunite is Installed
The installation of a gunite pool begins with excavation, where the area around the pool is cleared and the pool is dug out. The next step involves installing the pool plumbing for main drains, skimmers, returns, and other water features. The structure of the gunite pool is then created using reinforcing bars to provide strength and support. Once the bars are in place, the gunite mixture is loaded onto a hopper and sprayed through a hose with the addition of water. After the gunite cures, tile and coping are installed at the top of the pool, followed by a final finish on the rest of the pool to smooth out any roughness.
Gunite Pool Cost
The cost of a gunite pool can vary depending on the size and features you choose. On average, a 14′ x 28′ gunite pool can cost up to $100,000, which translates to roughly $100 to $280 per square foot. Labor costs typically make up one-third of the total construction cost, with materials accounting for the remaining two-thirds. Additionally, the cost of a pool finish to go on top of the gunite adds around $10,000 to the material cost.
Pros of Gunite Pools
- Strong: Gunite pools are known for their durability and long-lasting construction.
- Customizable: Gunite pools can be built in custom shapes and sizes to fit your preferences.
- Several finish options: Gunite pools offer a variety of finishes, including tile, plaster, paint, and marble dust.
Cons of Gunite Pools
- Slower construction: The construction process of a gunite pool can take longer compared to other pool types.
- Expensive repairs: Repairs for gunite pools can be costly due to the specialized materials and construction methods.
- Surface maintenance: The surface of a gunite pool may require regular maintenance to keep it in top condition.
Gunite vs. Other Pool Materials
When comparing gunite pools to other common pool materials like shotcrete, concrete, fiberglass, and plaster, there are key differences to consider:
- Shotcrete pools: Shotcrete is similar to gunite but is shot wet and applied in a single session, making it more expensive and prone to cracking if not done correctly.
- Concrete pools: Concrete pools offer exceptional durability but are limited in features and prone to cracking over time.
- Fiberglass pools: Fiberglass pools are cheaper than gunite pools and offer unique finishes, but may require costly repairs after around 30 years.
- Plaster pools: Plaster pools provide a wide variety of colors and textures for customization, and with proper maintenance, can last for several years.
It’s important to note that while concrete pools may seem similar to gunite pools, the construction process and materials used differ significantly. Gunite pools are specifically designed to minimize the risk of cracking and can be converted into salt water pools with proper maintenance.
In conclusion, gunite pools offer a durable and customizable option for homeowners looking to invest in a long-lasting pool. By understanding the unique benefits and considerations of gunite pools, you can make an informed decision when choosing the right pool material for your needs. With proper care and maintenance, a gunite pool can provide years of enjoyment and relaxation for you and your family.
