In-ground swimming pools come in many standard shapes and sizes, and experienced pool builders are able to custom make anything a homeowner can dream up. Inground swimming pools are built with an amazing variety of different techniques to meet the needs of the proposed pool design, to hold up in your climate or ground conditions and pool builders will use the technique that has proven to be the most successful for them. Inground swimming pools are considerably more expensive than above ground swimming pools to purchase and install, and the equipment, accessories and maintenance of an inground pool will be more expensive throughout the entire life of the pool.
Inground swimming pools can be made entirely of concrete, made with fiberglass or metal walls and a concrete floor, fiberglass or metal walls and a sand floor or be made entirely of fiberglass. Every inground swimming pool starts with a large hole excavated in the ground. Before any part of the actual pool is installed, the location of the filtration system and all of plumbing for the pool is planned and the plumbing is laid in place underground. Plumbing consists of a pipe for one or more skimmers, one or more return line fittings and one or more floor drains leading from the pool to the spot chosen for the pool equipment.
A pool that is constructed entirely of concrete will start with the placement and welding of reinforcing rods called rebar, around the entire interior of the pool. Concrete is either sprayed or poured onto the rebar, and allowed to set. A thick layer of plaster is typically applied to the interior of the pool, or a vinyl liner may be installed over the concrete.
Pools built with fiberglass or steel walls and a concrete floor start with the laying of the concrete floor. After the concrete has set, the fiberglass or metal walls and braces behind the walls are installed. The area behind the walls is filled in with sand or soil. The walls of this type of pool are typically built to be watertight, but a vinyl liner may be installed inside the pool. Pools built with fiberglass or steel walls and a sand floor start with the installation of the walls. The floor of the pool is then filled with sand, and a vinyl liner is installed to hold the water in the pool. Due to the lack of concrete this option will prove to be less expensive, but may not last as long.
Pools that are made entirely of fiberglass typically prove to be quickest to install and the least expensive, however these pools cannot be made very large. Fiberglass pools are a one-piece shell and made in a large mold. These pools can only be made so big, before the weight of the pool will crack itself during transportation. A fiberglass pool is brought to your font door on the back of a truck, so you are also limited by the amount of room you have to get the pool down your residential street. You should consider how much room you have to get the pool around your house into the back yard.
