Planning - Your first step in building an in-ground pool is to sit down with a professional pool builder. They will lay out a plan for you and get the necessary permits required to add on a pool. They can also line up the many subcontractors required to build the pool. These pools will take 2-3 months to build and will costs in the range of $35,000 to $50,000.
Spray in Gunite Shell - Many in-ground pool shells are made of gunite - a concrete type material composed of fly ash, cement, sand and some pea gravel. Gunite is often used because it is more flexible and is easier to apply then concrete. Gunite is brought in from the street through a pressure hose in a power form. Water is added at the nozzle and a paste form of gunite is sprayed into the hole and built up in layers to form a rough shell.
Lay Down Piping Around Pool - This pool has 9 major trunk lines to carry water to and from the pool. Four line carry water to the pump from the 2 skimmers, the Spa drain and the suction cleaner. Five lines are used to return water from the pump/filter/chlorinator to the return jets, the spa jets and the bubbler. Two separate conduits are also laid to provide electrical wiring between the control box and the two pool lights.
Lay Pavers - The surface around the pool is leveled with a layer of crushed stone and sand, and pavers are laid on top of this layer. Pavers are further leveled with a compactor. A row of pavers is mortared around the pool perimeter on top of the screening footer to keep the interior pavers in place.
Apply Pool Surface - A fine pebbled compound is shoveled onto to the surface of the pool shell and smoothed and leveled with trowels to a uniform thickness. The surface is then brushed to expose the aggregate and produce an attractive slip resistant finish. Marbletite and PebbleTec are two of the common products used to surface pools.
Final Inspection - The county performs a final inspection of the building, plumbing, and electrical.
