Concrete pools are some of the highest quality swimming pools built. When constructed properly, these pools offer years of use before requiring much maintenance or repair. The most popular type of concrete pool construction today is done with either shotcrete or gunite, which are mixtures of concrete and sand that are sprayed onto a metal frame.
Install a steel frame into the outline of the swimming pool, which will provide stability for the concrete once the pool is filled. Cover the sides and bottom of the basin with steel rebar.
- The rebar serves as a frame for the concrete and ensures the pool will maintain its shape and strength for a long time. Place the steel in grid form for greatest durability. Each area has its own building codes in regards to how the rebar should be installed, so learn the rules for concrete pool construction in your specific community. Framing may also be added at this time to create stairs or other interior features.
Spray gunite onto the steel rebar grid using a power sprayer, creating the actual pool basin.
- Gunite is either applied by professional pool installers or purchased through a gunite or concrete supplier for do-it-yourself use. Machines to apply the gunite can also be purchased or rented through these companies. Gunite is applied using a dry mix method, so no water is needed.
- Once the gunite is installed, it will need to be sprayed down with a hose every day for 5 days to assist the curing process.
Fill the swimming pool with water, either from a source in your home or by having water shipped in. Your choice depends on the cost of water in your area and the size of your swimming pool construction.
- After the pool is filled, it will be ready for use after the proper chemicals are applied and the water is tested for safety. You can learn about how to treat your water through your pool supply store or the professionals that handle your concrete pool construction.
