If you look in any Yellow Pages directory under the category Swimming Pools, you will commonly find more pool service companies than builders, which illustrates the tremendous need for service and repair of concrete pools. A concrete pool is rigid and inflexible, so minor ground movements can cause it to crack, whereas a fiberglass pool can flex substantially without breaking.
Algae can grow right through the walls of concrete pools, destroying the plaster finish and causing damage to the pool's structure. The only way to eliminate the algae is to acid wash the surface, which can cause abrasive conditions. However, even acid washing does not always eradicate all of the algae. The only options available to the homeowner at that point is sandblasting, re-plastering and repainting, which cost enormous amounts of time and money. The good news? With its nonporous gel coat, fiberglass is impervious to algae.
The surface of fiberglass pools remains like new, surviving all types of weather conditions. With its skin-soft, satin smooth finish, fiberglass never requires repainting, re-surfacing, or re-plastering.
Maintenance of a concrete pool during the curing time is a cumbersome task. Alkaloids can seep into the water, requiring constant filtration and chemical balancing. A fiberglass pool does not leach any materials into the pool, thus saving time in maintenance and money in both chemical usage and electricity.
