When it comes to constructing a pool, the type of concrete used plays a crucial role in it’s durability and longevity. Two commonly used types of concrete are shotcrete and gunite. Shotcrete is a wet concrete mixture that’s fully mixed prior to being shot out of a hose, while gunite is a dry concrete mix that only combines with water at the nozzle during the spraying process. Let’s delve deeper into the characteristics and benefits of each type of concrete for pools.
What Kind of Concrete Is Used in Pools?
Concrete pools can be constructed using either shotcrete or gunite, both of which are popular choices in the industry. The primary distinction lies in the timing of when the concrete mixes with water during the construction process. Shotcrete is a type of wet concrete that’s fully mixed prior to being propelled out of a hose. This method allows for greater control over the consistency and strength of the concrete, resulting in a more precise and smoother finish.
On the other hand, gunite is a dry concrete mix that only mixes with water at the nozzle when it’s being sprayed. This technique offers flexibility in terms of adjusting the mix on-site, allowing for alterations to be made based on specific project requirements. One advantage of using gunite is that it can be applied to vertical or overhead surfaces without the need for extensive formwork, making it a versatile option for pool construction.
An important aspect to consider when constructing a concrete pool is proper reinforcement. Steel rebar is commonly integrated within the concrete to enhance it’s strength and structural integrity. This reinforcement is crucial in ensuring the pools ability to withstand the constant pressure exerted by the weight of the water.
While shotcrete provides a more controlled and smoother finish, gunite allows for on-site adjustments and can be applied to various surfaces. Regardless of the method chosen, reinforcing the concrete with steel rebar is essential for a durable and reliable pool structure.
It’s important to ensure the strength and durability of a gunite pool structure. During the building process, the floor is constructed to be a minimum of 10 inches thick, while the walls are at least 8 inches thick. Additionally, the bond beam, which plays a crucial role in providing stability, is built to be 12 inches thick. This ensures that the pool structure is strong and capable of withstanding the pressures of regular use. Once the construction is complete, the pool is connected to the equipment pad and undergoes pressurization to ensure optimal functionality.
How Thick Is the Concrete on a Gunite Pool?
Once the gunite pool construction process begins, the thickness of the concrete becomes a crucial aspect of creating a strong and durable pool structure. Shooting the gunite involves the application of a high-pressure mix of cement, sand, and water onto the rebar framework, forming the pool floor, walls, and bond beam.
To ensure a solid foundation, the gunite pool floor is typically constructed to be a minimum of 10 inches thick. This thickness provides stability and reinforces the pools ability to withstand the weight and pressure of the water. It also adds strength to support the weight of people and any potential external forces.
Moving upwards, the walls of a gunite pool are typically built with a minimum thickness of 8 inches.
However, the most critical area in terms of thickness is the bond beam. Serving as the connective element between the pool walls and the deck, the bond beam is crucial for preventing structural failure and maintaining the pools longevity. Therefore, a minimum thickness of 12 inches is generally applied to ensure that the bond beam can effectively distribute the forces that may occur during the pools use.
Throughout the entire gunite pool construction process, the plumbing is intricately integrated into the structure. The plumbing lines, including the main drains, return lines, and skimmers, are securely embedded within the concrete to avoid any potential leaks or damage. This is done prior to the gunite application, allowing for the entire system to be pressurized and tested for any potential issues.
By adhering to these minimum thickness standards during the construction of a gunite pool, professionals can ensure a robust and reliable pool structure.

When homeowners decide to build an in-ground pool, they often wonder about the materials used. Pools are typically made of steel-reinforced concrete, forming a durable and long-lasting shell. Concrete and plaster have been the go-to materials for building pools for many years, standing the test of time since the residential pool craze began. Now, let’s take a closer look at the construction process and advantages of using concrete or cement for building pools.
Are Pools Made of Concrete or Cement?
Pools made for in-ground use are typically constructed using steel-reinforced concrete as the primary material. This combination of concrete and steel creates a durable and strong shell that can withstand the pressure of the surrounding earth and water. Concrete serves as the main component, providing stability and structure to the pool.
The process of building a concrete pool involves constructing a framework or skeleton using steel reinforcement bars. Once the framework is in place, a mixture of concrete is poured into it, forming the pools walls and floors. The addition of the steel rebar adds strength and ensures that the concrete doesn’t crack or collapse under the weight of the water.
After the concrete has cured, a layer of plaster is applied to the pools interior. Plaster can be tinted or dyed to achieve different colors and aesthetics, making it a versatile option for pool owners.
Although the terms “concrete” and “cement” are often used interchangeably, they refer to different materials. Cement is an ingredient used in the production of concrete. It’s a powdery substance that, when mixed with water, forms a paste that binds the aggregates and sand together, resulting in concrete.
Concrete provides the strength and structure required for the pool, while plaster serves as a protective and aesthetically pleasing layer. These materials have been used since the early days of residential pools and continue to be the go-to choice due to their durability and reliability.
