Introduction to Concrete and Gunite Pools
Both concrete and gunite pools are constructed using concrete, but they differ significantly in their application and finishing processes. Concrete pools are built using a method where concrete is poured into a mold or form, allowing it to set and harden before being removed. This process is akin to building a house foundation, where the concrete is formed into a solid structure. On the other hand, gunite pools involve spraying a mixture of cement, sand, and water onto the pool’s steel reinforcing structure (rebar) using a high-pressure hose. This process creates a strong, durable shell that is then finished with a plaster coating.
Construction Process: A Closer Look
Understanding the construction process of each type of pool can provide valuable insights into their differences.
Concrete Pool Construction
The construction of a concrete pool begins with excavating the site to the desired shape and depth. A framework of steel rebar is then placed within the excavation to provide structural support. Next, a thick layer of concrete, typically 6-8 inches, is poured into the framework, and the concrete is allow to set. After the concrete has hardened, the form or mold used to shape the pool is removed, revealing the pool’s structure. The pool is then finished with a layer of plaster or another decorative coating.
Gunite Pool Construction
In contrast, the construction of a gunite pool begins similarly with excavation and the placement of a steel rebar framework. However, instead of pouring concrete, a mixture of cement, sand, and water, known as gunite, is sprayed onto the rebar using a pneumatic gun. The gunite is applied in layers, each layer being allowed to set before the next is applied, until the desired thickness is achieved. The gunite pool shell is then smoothed and finished with a layer of plaster.
