Not All Fiberglass Pools Are Manufactured the Same
Most people don’t realize it, but the way your pool is made can make all the difference in how long it lasts and how much you enjoy it.
Engineered to Last. Designed for a Lifetime of Enjoyment
Every great pool starts with a precise mold.
The Mold – The Starting Point for Every Great Pool
Every fiberglass pool starts with a carefully crafted mold. It’s the critical first step in creating a pool shell that’s strong, consistent, and built to last for decades.
At our manufacturing campus, we go to great lengths to protect these molds. They’re stored indoors, moved on flat surfaces, and handled with care to reduce stress and wear. Why? Because a precisely maintained mold means a more accurate, reliable pool shell every time.
Less stress on the mold means less stress for you, and more time spent enjoying the water.
The first thing you see, the last thing you want to worry about.
Gelcoat – The Color You Choose, the Surface You Feel
The gelcoat is the smooth, high-gloss layer that gives your pool its color and shine. It’s comfortable for bare feet and paws, algae-resistant to keep your water clearer, and scratch-resistant for active families.
Plus, River Pools leads the industry in gelcoat testing, so you can feel confident your pool will look great for years to come.
Choose the color you love, and enjoy a finish that’s built to last.
A critical layer for long-term durability.
Vinyl Ester Barrier Coat – A Hidden Layer of Protection
Before the first layers of fiberglass are added, every River Pools shell gets a critical barrier of vinyl ester resin. This waterproof layer helps prevent blistering, protects the gelcoat, and acts as a powerful shield against moisture intrusion.
It’s a hidden but essential step that helps keep your pool looking beautiful, strong, and ready for decades of use.
The backbone of a strong, durable pool shell.
Chopped Fiberglass – The First Layer of Structural Strength
Once the vinyl ester barrier coat is in place, the first structural layers are built using chopped fiberglass. This material starts as strand roving—long, continuous strands of fiberglass that are chopped into shorter lengths by a specialized chop gun, then mixed with resin and catalyst.
When sprayed onto the mold, this chopped fiberglass forms a dense, reinforced layer that gives the pool shell the strength and flexibility it needs to handle water pressure, ground movement, and decades of use. It’s a critical step in building a tough, reliable pool shell.
Adding strength to your pool shell.
Hand-Laid Woven Roving – Extra Reinforcement Where It Matters Most
After the chopped fiberglass layers are in place, the next step is adding hand-laid woven roving. Unlike chopped fiberglass, this material comes in thick, interwoven sheets that provide an extra layer of strength where it’s needed most—like steps, benches, and stress points in the pool shell.
This layer helps prevent flexing and adds durability, ensuring your pool is ready for decades of use. It’s a critical part of building a pool that’s as strong as it is beautiful.
Critical support for flat and vertical surfaces.
Honeycomb Core – Adding Rigidity Where It’s Needed Most
Honeycomb core is a lightweight, rigid material used to reinforce specific areas of the pool shell—like sidewalls, steps, benches, and tanning ledges. By itself, it isn’t particularly strong, but when layered with chopped glass and resin, it adds critical stiffness exactly where it’s needed.
This strategic reinforcement helps the pool maintain its shape over time, reducing the risk of flexing, cracking, or structural stress. It’s one more way we build strength into every pool shell.
ADDED STRENGTH WHERE IT COUNTS.
Stitch Matting – Extra Reinforcement for High-Stress Areas
Stitch matting is a thick, multi-layered material that adds bulk, strength, and impact resistance to critical areas of the pool shell. It’s made by stitching together layers of fiberglass mat and woven roving, creating a dense, durable layer that helps protect the shell and gelcoat from undue stress and cracking.
This reinforcement is strategically placed in areas that may experience more flexural stress, like steps, benches, and corners, helping your pool maintain its shape and strength for decades of use.
A well-built pool shell makes all the difference.
Spend More Time Making Memories, Less Time Worrying
You deserve a pool that’s ready to enjoy, not constantly fixed. That all starts with one that’s been crafted with carefully selected materials, applied in exactly the right place.
When your pool is built using high-quality gelcoat, vinyl ester barrier coat, chopped fiberglass, hand-laid woven roving, honeycomb core, and stitch matting, you get a shell that’s strong, resilient, and ready for decades of summer days.
