Comparison between Above Ground and In Ground Pools
Swimming pools can be built in ground or above ground. An above ground pool typically cost less and takes one to two weeks to install compared to eight to twelve weeks for an in ground pool. Above ground pools are usually round or oval in shape with the shape being either rigid or soft side. They will have a visible structural frame made of galvanized steel or other type of strong, corrosive resistant material. Frames are available in different heights and colors. An above ground pool will also have a liner as an interior finish and are available in a variety of patterns and colors. The liner should be puncture resistant. Decking is another component of an above ground pool. The decking can be constructed from stamped concrete, natural stone, natural wood, a colored or textured coating, pavers or tile. Once installed, aboveground pools cannot be upgraded.
There are three options to choose from if an in ground pool is desired. In ground pools can be manufactured as a one-piece fibreglass pool, be made from a vinyl-liner, or made of concrete or plaster. High quality gunite (reinforced concrete) pools or plaster are the most elaborate and are permanent and reinforced. The interior can be made of white or colored plaster, pebble aggregate, polished marble, glass bead, or tile. One-piece fibreglass pools are pre-made in a mould and then transported to the job site. They are made from a nonporous gel coat finish with a reinforced backing. One-piece fiberglass pools are available in a variety sizes, shapes and color options. In ground vinyl pools are reinforced with vinyl-liners and come in up to twenty pre-fabricated shapes. Interior finishes come in many patterns and multi-colors.
In Australia, there are three categories that regulate pool construction: safety, council, and water.
