So just what is a concrete swimming pool?
This type of pool is custom built on site offering you many different styles and options. A steel reinforced structure is first built. While these steel rebar frames are being installed, plumbing pipe will also be installed. The plumbing pipes that are being installed are longer than you need, but after being checked for leaks, they will cut off flush with the edge of the pool.
Gunite, sometimes called shotcrete is sprayed over this steel frame. This spraying process must be done by an expert experienced with the nozzle operation. The skill in doing this spraying is critical to producing a strong pool. The thickness of the gunite will depend on pool design, budget, and ground conditions. Another factor in the thickness and amount of steel rebar reinforcement required is the climate. The further north the pool is being installed usually means thicker concrete and more rebar. This is due to the freeze/thaw cycles between winter and summer. The pool must be strong enough to withstand these forces without cracking. One side effect of this is that the price for this type of pool will be much higher in places such as Maine vs. locations such as Florida. The next step will be to install the plaster over the gunite.
Once the gunite is dry, it is carefully smoothed to prepare the surface for the plastering stage. The plastering is available in different colors, along with many different colors and styles of ceramic tile that can be used for the border around the pool. The construction is complex and should be done by very experienced pool installers. This type of pool construction, generally takes longer to install and is much more expensive than either a Liner Pool or a Fiberglass Pool.
