Setting the Standard for Pool Structure


The shell of your pool is similar to a home’s foundation; it’s the most critical and expensive part of a pool.

Gary Pools is the #1 authority on pool structure. We pioneered the structural method used in more than 30,000 pools in and around San Antonio. Additionally, our Cantilever design works so well that it has been reproduced by other top pool builders in the area.

A pool is likely to be one of your most costly purchases, and therefore, it’s not worth taking any risks when it comes to the structure and longevity of your pool. In fact, some pool companies won’t offer you a structural warranty if they have had a pool fail in your neighborhood. Rather than fixing their design, they simply choose to avoid the area.

Even worse are warranties that expire or are nontransferable. The average homeowner moves every 10 years, so their “Lifetime Warranty” is, on average, only a ten-year warranty! Our warranty is transferable because we have confidence that our pool structure is built to last for generations.

Lifetime Warranty

Structural Lifetime Warranty

The Gary Pools Structural Schedule is renowned for its excellent integrity. In 1961, Leif Zars designed a monolithic wall-to-walk cantilever structure, specifically designed to solve problems created by Texas’ expansive soil conditions.

Industry leading patents and major innovations allow us to give a Lifetime Structural Warranty. As an added value to your home, our warranty is transferable.

Cantilever Beam

With the Gary Pools Cantilever Structure, you get so much more than with the traditional beam pool design. Even if you choose to only build half cantilever half beam, the advantages are still there. We have built all types of pools for over 65 years, so we’re ready to help you make the best decision for your backyard.


  • 8x the strength of traditional beam structures
  • Doubles as a walkway
  • Insulates tile and coping from adjacent deck movement

The WetMix Shotcrete is superior to the DryMix Gunite Method. While both can have the same outcome, DryMix Gunite is much riskier and requires the home owner to wet the curing pool shell for 7 days.


  • We spec 5,000 PSI concrete
  • Our pools have strong 8″ to 11″ thick walls & floors that make up the pool shell. That is 33% more than any builder that specs a 6″ thickness


Steel is placed every 9 inches to form a 9″ x 9″ reinforcing grid in all floors and walls, at a minimum. We use only #4 bars with a minimum yield strength of 60,000 pounds.

Steel is another critical structural component that we do not cut corners on. Rather then #3 bars (3/8 inch) we use #4 bars (4/8 inch or 1/2 inch), #4s are thicker and tougher to install, but it’s worth it.

The thicker bars are harder to install in 6″ thin walls, which other contractors may install. But with our 8″ thick walls, we can place the 1/2″ bars with plenty of cover.

And, of course, we only use galvanized reinforcing tie wires. We do this to reduce the chances of rust spots developing years down the road.
