5 Main Stages of Pool Construction
Once you’ve finalized the design of your dream pool, established exactly where your pool will be dug and your contractor has secured permits. By this time any large obstructions or loose debris on your pool site should already be cleared away and the ground leveled/evened. Digging out a swimming pool will require the digging equipment to access to your backyard. Be prepared as it may be necessary, to remove fence spans or make gates larger for equipment entry.
Stage 1: Pool Shell
Layout and Excavation - A trained professional will begin by staking out the shape of your pool, inspect the layout and confirm the measurements and design. A qualified excavator will begin digging out the pool depths and carving the shape into the soil. The pool is over dug to allow for the construction of the pool shell and the excavated soil can be used as backfill on site or hauled off.
Steel - The shell of your pool depends on steel reinforcement bar to be strong enough to hold water and prevent cracking under the expansion and contraction of the surrounding soil. A steel rebar grid is formed into the outline of your pool and serves as a frame for the concrete and ensures the pool will maintain its shape and strength for greatest durability. Framing may also be added at this time to create stairs or other interior features.
Gunite - is a mixture of cement and sand that is sprayed over the rebar basket and builds up within it until the pool walls reach the proper thickness. This becomes the bond beam which may be over a foot thick. Once gunite is in place the surface of the shell is hand finished
Stage 2: Plumbing & Electrical
At this stage, the piping and wiring necessary to operate the pool must be put into place while there is access. This may require additional surface trenching to the pool equipment enclosure or to power and water connections. At this point, the heater, filter, and any other add-ons will be installed.
Our plumbing crew will install all circulating lines and filtration equipment. Note that if you have closed to have a gas heater installed, the homeowner is responsible for providing gas service and you will need to call a licensed gas plumber as soon as the heater is in place. Your gas plumber can contact us for connection requirements and pipe size.
Electrical work and grounding of the pool equipment is done by a licensed electrician according to the National Electric Code and local government requirements. An inspection of the electrical system will be conducted by a building inspector and is required before pouring the deck around the pool. If your existing electrical panel cannot handle the extra load for the equipment oftentimes a sub-panel must be installed. Please refer to your Construction Agreement for details on providing adequate electrical service.
