Fiberglass Pool - a pool whose surface is composed of a prefabricated fiberglass shell, or from fiberglass sidewalls set in a concrete floor. In both cases, the fiberglass material is sprayed as a gelcoat resin into a mold, then allowed to harden. Colors are usually contained in the gelcoat, but fiberglass surfaces can also be painted or otherwise refinished.
Often the most economical type of pool, fiberglass is preferred by buyers who want a quick, easy installation process. However, fiberglass construction can be vulnerable to cracking, fading, and flotation.
The structure of a fiberglass pool may be one of two types:
- Walls - usually about 3 feet high, made from one continuous length of fiberglass, or sections bolted and sealed together. Pools made using this method can be almost any size and shape.
- Shell - entirely prefabricated in a single piece, or a few pieces which are bolted together. Manufacturers offer a range of styles and sizes, which are simply lowered into the hole atop a bed of sand, and attached to plumbing which runs up through the substrate.
Though deterioration of the gelcoat is a common occurrence, it can often be repaired without difficulty. Fading or color changes can be covered with water-resistant paint, and cracks are relatively simple to fill.
