Gunite swimming pools are a popular choice!
To build one of these pools, the construction crew digs a hole, assembles a framework grid with Y8mm steel reinforcing rods (rebar) The rebar rods are spaced at about 200mm² and secured at each intersection. When the grid is in place, the crew sprays a heavy coating of gunite, a mixture consisting of cement and sand, around the rebar, under pressure.
What is Gunite?
Gunite is sprayed concrete through a hose and pneumatically projected at high velocity onto a surface, as a construction technique. Concrete is sprayed and compacted at the same time, due to the force of the compressed air. It can be sprayed onto any type or shape or surface, including vertical or overhead areas. Gunite is commonly used for application of inground swimming pool installation. Gunite swimming pools are typically more durable and longer lasting than other conventional materials as hand packed concrete.
Additionally, the use of gunite allows for customization in shape, depth, and style not available in traditional pool kits. Gunite pools are often referred to as designer swimming pools. As the gunite hardens, it becomes extremely durable and can withstand pressures up to 4,000 PSI. This makes gunite suitable for even the deepest of pools. When built by a knowledgeable contractor and properly maintained, a gunite pool can last for 100 years or more.
Advantages of a Gunite Pool
- Gunite pool can be designed to complement your house and personal taste.
- The structure is durable and can be strengthened even more if needed.
- Gunite pools are built on site, and make access in your yard much easier than pre-molded shells.
Disadvantages of gunite Pools
- Because the concrete needs to cure, it takes as much as 5 weeks to build gunite pools from scratch.
- Due to the rigidness of gunite this product is not advised in turf areas or areas with lots of soil movement.
- Gunite pools tend to be more expensive than fiberglass shells due to the labor-intensive process.
