San Juan Pools manufactures the highest quality /
fiberglass pool shell in the industry.
To explain the engineering of our product and what makes our shells different
than the rest of the industry we first need to explain a little about materials
The type of resin makes a difference.
From the marine industry we have learned that only Epoxy type resins are
impervious to water. Vinyl Ester resins are made with many of the same
products that go into epoxy. This is why all good boat builders and all
good swimming pool builders use a Vinyl Ester resin for the layer of fiberglass
next to the surface. Vinyl Ester resins also have better mechanical
properties than polyester resins. This is why the very best boat builders
continue the use of Vinyl Ester resins throughout the laminate. At San
Juan Pools we realize that the back of the pool shell needs to be impervious to
water just as the front, and that the better mechanical properties of Vinyl
Ester resins make for a stronger shell. When looking at the total cost of
a pool project, it does not make sense to use cheap general purpose resins in the manufacturing
of your pool shell. San Juan Pools is the only fiberglass pool builder that uses
Vinyl Ester resin throughout the laminate.
We use a proprietary Vinyl Ester resin bought exclusively
The type of fiberglass reinforcement makes a difference.
The aerospace and marine industries would never think of using chopped
fiberglass for structural components, yet most of the fiberglass swimming pool
industry uses chopped fiberglass for the majority of their shell.
Anything that is sprayed on a mold with a gun is not structural!
Filled resins, ceramic cores and chopped fiberglass make a part thicker
(stiffer) but do not add significantly to the strength of the laminate.
Which do you believe is stronger, a continuous piece of rope or a rope that has
been cut into little pieces and glued together? Woven roving is a fabric
made by weaving continuous strands of fiberglass together. San Juan Pools
uses at least 48oz per square yard of woven roving everywhere, with many areas
of the shell having more than 72 oz per square yard of woven roving.
We use American made fiberglass reinforcement bought
Having the best laminators in
the business makes a difference.
After picking the best materials for our product, we must make sure the
workmanship that goes into our product is also first class. At San Juan
Pools many of our laminators have been with the company for more than 20 years.
This leads to consistency of product. We value our employees as their
sense of quality is second to none.
Having the best management
team in the business makes a difference.
None of this would work without top quality management. We are
certified by the ICC-ES as one of the few manufacturers with a quality control
program that is internationally recognized. This also means our pool
shapes have been inspected as being compliant with NSPI/ANSI-5. This leads
to easier permitting since your inspector knows that the product is certified by
the same company that writes the building code. We are also a licensed
fabricator for the City of Los Angeles. This means our factories have been
inspected and are in compliance with our quality control program. No other
manufacturer has as long of a history, or has been in continuous compliance with
these internationally recognized organizations as San Juan Pools.
The first step in manufacturing your San Juan
Pool Shell is a clean waxed mold.
Next we cut materials (All fiberglass is hand
laid, none of our reinforcement is shot out of a gun)
All of our shells have a minimum of 48 oz per
square yard of woven roving everywhere.
First we apply the surface. Then we skin this with 1.5 oz
per square foot of chopped strand mat. Then we lay up the pool in panels
with each panel consisting of a 1.5 oz mat, a 24 oz woven roving, a 1.5 oz mat,
and another 24 oz woven roving. Deep pools get an additional layer of mat and
The pools are hand laid in panels.
Ribs are strategically placed to stiffen the
We have two types of surface finishes.
Our White and Sulli Blue pools use an
NPG/ISO (Neopentyl Glycol Isophathalic) based Gelcoat. This is specially formulated for the pool
industry, it is UV stabilized and corrosion resistant. The strength of
this finish is well proven with many pools having this finish that are well over
25 years old. As crystal clear water will always have a sparkling blue
look many pool owners see this as the most beautiful of all finishes.
We also have our new
Iridium colored finishes. This is a
solid surface material consisting of oven cured colored chips in a clear UV and
chemical resistant clear resin. This surface finish is backed up by a
color matched gelcoat that acts as a barrier coat as well as a primer for the
We thoroughly clean and inspect every part
when it is pulled off the mold.
All imperfections are repaired. This takes time, but only
perfection is good enough for a San Juan Pool.
Pools are tiled and outfitted as needed.
Finally, a beautiful San Juan Pool Shell is ready
to become part of your backyard dream.
