More than seventy years ago, people began building concrete swimming pools. In addition, for thousands of years, man has built boats constructed from wood. However, in the mid 1950’s, fiberglass was introduced to both of these industries, and a quiet revolution began. Most people are familiar with the durability, lasting beauty, and the ease of maintenance and repair of fiberglass boats – people buy them for those reasons even though they cost a little more than wood boats.
Most people are not aware of the many and varied uses of fiberglass in other industries and products. It is being used in helicopter blades because of its strength, flexibility, and its durability against cracking. It is being used in water storage and septic tanks because it will not deteriorate or corrode. It is being used in the construction of airplanes, automobiles, appliances, insulators, transformers and dozens of other products, all because of its strength and durability.
Reasons to choose Fiberglass
In other words, the gelcoat finish on the San Juan pool greatly simplifies water maintenance procedures. If a fiberglass pool is neglected and algae were to grow, even if the pool was not filtered for an entire year, it is a simple matter of brushing the pool to remove the algae from the walls. In concrete pools, algae can grow right through the walls of the pools, destroying the plaster finish and causing damage to the pool. The only way to remove it is to acid wash the surface. This requires scrubbing the floor and walls with acid, which makes the pool very rough and does not always get out the algae that has penetrated the walls of the pool. You would then have to sandblast and re-plaster or re-paint the pool – each very costly resolutions. In vinyl pools, the algae would destroy the flexibility of the liner and require costly replacement. It is also not uncommon to see enormous amounts of black algae behind a vinyl liner pool. This requires extensive and costly measures to prevent damaging a new liner.
Most San Juan Fiberglass pools, even those with tapered bottoms, can be installed above ground. San Juan pools have been installed for many years on the rooftops of apartment buildings and hotels across the country. One of the more recent installations of this type was of two San Juan, Manatee model swimming pools on the 42nd and 43rd floor of the RIO Hotel
in Las Vegas, Nevada. They knew they could not afford to take any chances so their obvious choice had to be San Juan!
The concrete decking around a fiberglass pool is attached to the flexible lip of the pool. This allows the decking to move during expansive and wet conditions resulting in less of a tendency for the concrete to crack. The sand around our pools acts like a giant sump, carrying water away from under the deck and dissipating it through the sand and into the earth around the pool. This also contributes to keeping the deck from cracking during expansive conditions. Compare this to the way decking is poured around a concrete pool. The decking on other types of pools is commonly poured from the building foundation over to the edge of the pool. During excessive moisture and expansive conditions the decking cannot move enough laterally, becoming more susceptible to breaking and buckling in an upward movement than the decking around a fiberglass pool.
