Although there are a wide variety of manufactured pools on the market (concrete, fiberglass, and vinyl), concrete pools represent 60% of pools being built today. Concrete pools offer limitless options for shape, configuration, and spa features. The excavation site is reinforced with steel and provides a sturdy support for pools of any shape or size. Fiberglass pools are manufactured in a factory and the prefabricated pool arrives at its destination and is set in a previously excavated site. Fiberglass pools constitute 7% of the market and are limited in the variety of shapes available. Vinyl-lined pools arrive in a kit with construction completing at the site and represent 33% of the pool market. A custom fit vinyl liner is installed after the decking is completed and the structure is then filled with water. Previously limited to geometric designs only, free form options are now available.
In the design and manufacturing of pre-fabricated aboveground pools, the cost of fabrication continues to be a major concern. Pools have to be manufactured in a variety of styles and sizes to accommodate the available space requirements of the customer and the variety of components necessary for manufacturing is quite large. Designs that can incorporate this flexibility and reduce the necessary inventory required to accommodate a variety of sizes and structures have begun to arrive in the above ground swimming pool manufacturing marketplace creating easier systems to erect without sacrificing stability.
