Why Fiberglass?

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.

San Juan has been making fiberglass swimming pools for over 57 years

With well over 70,000 being installed from coast to coast. Our first pool, installed in Seattle, in 1958, still retains its beauty today. This lasting beauty and the low maintenance is what keeps more and more intelligent buyers investing in San Juan Fiberglass Pools and Spas.

Reasons to choose Fiberglass

Atlantic paver deckingSan Juan Fiberglass Pools are actually more permanent than concrete pools, not requiring the remodeling and maintenance that is necessary with concrete. Fiberglass is also more resistant to stains than a plaster finish and it never needs painting. The non-porous gel coat surface of a San Juan pool is an isophthalic polyester resin with color pigment mixed in. This gel coat is chemically bonded to the fiberglass and becomes an integral part of the pool shell. The 32-mil gel coat finish is nonporous, chemically inert, will not affect the chemical balance of the pool water, and is extremely resistant to acids and oxidizers. Algae cannot penetrate the finish. Stains, which may form on the gel coat, can be easily dissolved by the addition of a chemical stain remover to the pool water.

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.

seasideSince concrete is rigid and relatively inflexible, minor ground movement can cause the pool to crack. A San Juan Fiberglass Pool can flex substantially without breaking. San Juan Fiberglass pools are 17 times stronger than concrete pools and have a tensile strength of 11,300 pounds per square inch. In other words, it requires 11,300 pounds of pull to fracture one square inch of a San Juan Pool. This flexural strength allows your San Juan pool to expand or contract with expansive soils, earthquakes and freezing temperatures without damage.

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.

We do know that we have been making our pools for over 49 years, installing well over 60,000 pools from coast to coast. San Juan Fiberglass Pools are installed in all climates – from areas with heavy rains to severe freezing temperatures to the heat of the deserts. We have found that our product is impervious to many things and this confidence, along with the growing demand and successful use of other fiberglass products, allows us to warranty our pools for a full 25 years (non-prorated) in order to protect your investment. Since most states consider ‘lifetime’ to mean 7 years, our 25-year warranty is over 3 times as long as most lifetime warranties.
San Juan Fiberglass Pools are manufactured on a mold in a controlled factory environment under strict supervision, resulting in a predictable, high quality product right down to the tile.  Each pool model is identical to the one before it, and the pool shell construction is virtually complete when it shows up at the job site.  Since it comes to the job in one piece, it eliminates many of the phases required to build a concrete pool – your yard isn’t a mess for months waiting for all the phases of concrete construction to take place. Also, you do not have the continuous parade of sub-contractors coming and going during this time. Under normal conditions, our pools are installed in a matter of days with only a small crew.
Due to the smooth, non-porous permanent finish of a San Juan Fiberglass pool, it does not require the acid washing, sand blasting, re-plastering or re-painting necessary with concrete pools. In a concrete pool the plaster finish actually deteriorates and has to be re-painted, resurfaced or re-plastered. This is not necessary with San Juan pools, so over the life of the pool, fiberglass will save you thousands of dollars in maintenance and remodeling costs, never mind the aggravation and loss of swimming time.
Liners cost thousands of dollars to replace.  Vinyl Liners are very susceptible to ultraviolet degradation and, even with the best of care, require replacement every few years with an average cost of $2,000 to $2,500. The smooth, non-porous, permanent finish of a San Juan Fiberglass pool will not degrade due to exposure to sunlight.  And, unlike vinyl liners, fiberglass is not susceptible to pinholes or tears, which means no unsightly patches.
Since a San Juan Fiberglass pool does not leach any material into the water (i.e., alkaloids and other materials from a concrete or plaster finish) you do not have to filter the pool as long to try to remove these foreign materials from the water. A fiberglass pool can reduce your electric costs by over 30% due to more efficient filtration and reduced operating time.
San Juan Fiberglass Pools save you money on chemicals for the same reasons they save on electricity. With no alkaloids being constantly leached into the water it is not necessary to use acids except in rare occasions, and the amount of chlorine needed is reduced substantially. These savings in chemicals can be as much as 70% over concrete pools.
