This pool is manufactured from a fiberglass-reinforced material that has been formed into a certain shape and size on a preformed mold at the factory. The surface material is placed over the mold and formed into shape. It is then coated with fiberglass. This pool does not use external braces, but it must be installed in a specifically dug hole and must be supported with the proper back fill according to the manufacturer's instructions.
The pool leaves the factory on a flatbed truck and at the job site a crane is used to remove the pool for placement in the excavated hole. Since most manufacturers offer certain size and shape molds, unlimited sizes and shapes are not available. Installation of this pool is fairly quick. Price wise, Fiberglass pools are usually much more expensive than vinyl liner pools, but less than concrete.
The homeowner needs to be very satisfied with their pool selection before the signing of the contract. This pool is not manufactured on site and has to be manufactured in a special mold, and then delivered to you. There is no changing your mind once the job has started. Do your homework first and choose the shape and size that will fit your family's needs.
