Trying to decide whether to go with a new gunite, vinyl or one-piece fiberglass pool? Following are some facts about all three to help you make your decision:
Concrete (or gunite) pools are rigid and do not flex. Minor ground movement (such as that which can occur during freezing and thawing in harsher climates) can cause concrete pools to crack; while fiberglass pools will flex 12” before cracking or breaking. Algae will grow on the porous surface of a concrete pool, resulting in the need for periodic cleaning. This cleaning process requires acid washing of the pool surfaces, which in-turn causes these surfaces to become more abrasive. After a number of acid washes, the concrete pool will need to be sandblasted, re-plastered and re-painted. This is costly in both time and money. On the other hand, fiberglass pools have smooth, non-porous surfaces that will not harbor algae, and do not require the same sort of treatment.
Vinyl liner pools often require replacement of the liner every 7-10 years. Their exposure to the ultraviolet deterioration from the sun and the corrosive effects of the harsh chemicals used to sanitize these pools on a regular basis takes its toll on such liners. The surface of the fiberglass pool will remain like new (for the life of the pool, depending on the manufacturer) and can withstand pets and children’s pool toys. No further maintenance is necessary.
