Foam Core Construction in the Pool Trade

Foam core construction is becoming increasingly more popular in the pool trade says Nathan Giffin of Vertical Artisans.

Foam Core Construction in the Pool Trade

Foam core construction is a relatively new technique in the world of swimming pool construction, but it is quickly gaining popularity due to its numerous benefits. This construction method involves using foam boards as the core material, which are then covered in a layer of concrete. The resulting pool is lightweight, energy efficient, and cost-effective.

To get a better understanding of how foam core construction is being applied in the pool trade we consulted with Nathan Giffin. Giffin is an expert in the field and has been working with foam core construction for over a decade. He has taught countless professionals and contractors on the technique and has helped bring it to the forefront of the industry.

Giffin has been teaching the technique of foam core construction to pool builders who are looking to add this building technique to their repertoire. He says this technique is particularly enticing for those in the pool trade. “With foam core, you can build outdoor kitchens, jump rocks, fire pits, bridges, and you could have rock work actually emanating up out of the pool onto the decks and over the decks,” said Giffin.

Giffin says the future of foam core lies in its strength and versatility. “For decades, the Department of Transportation and various structural engineers and civil engineers have been using foam core in roads, highways, and things like that to displace a lot of material. It’s really beneficial because it can handle a lot of load,” explained Giffin.

That foam core construction has become dramatically more popular in the pool trade is no surprise to Giffin who indicated that contractors may be looking for alternatives to offset the rising cost of construction materials.

One of the primary reasons he is such a proponent of foam core construction is that it is incredibly durable and long-lasting. Giffin says that foam core provides a strong foundation for elements like rock waterfalls, slides, and grottos, and that concrete stone facing adds an extra layer of protection. Consequently, he feels this makes foam core construction a wise investment for those looking to add a swimming pool to their property.

“The first mountain I ever built at a pool with my colleagues, we did steel rebar construction, which is your typical method. You’ll have a worker bend up all the steel, and then you’re welding it, and then you’re backing it and shooting it. By the time you’re all said and done, you’ve got six to eight inches thick of concrete,” explained Giffin.

“We had to dig about 18 caissons just to support the weight of 99 yards of concrete. We shot that for a waterfall that surrounded a pool slide. Six years ago, I did a slide of a similar size, and I used 60 billets of foam. For this project, we used less than twelve yards of concrete, and it’s just held up like a champ,” said Giffin.

Giffin says that the technique is bound to become more popular with homeowners as they become more aware that alternatives like foam core exist. The techniques that professionals like Giffin are using allow for a dramatically shorter turnaround time.

“For a medium-sized mountain, we can probably have the foam carved up in about a week. We’ll actually sculpt this stuff in warehouses and then have the client come out and actually walk on it,” explained Giffin.

“They’re completely bedazzled over the entire structure because it’s so large,” said Giffin who explained that once the client has had an opportunity to view the structure, it’s then scheduled for delivery.

“We put it in a truck, bring it out to the job site,” explained Giffin, “within day one, it’s delivered and glued together. Then all of our pipes are run and we’re structure coating it. That all happens on day one. The rest of the week, we’re just spraying the concrete on and finishing it. I’ve finished very large structures inside of a two-and-a-half week time frame.”

That foam core pool construction is a unique and creative way to build large, complex structures with simple tools was the net-net we got from Nathan Giffin. By using hot wires on the foam structure, you can create intricate sculptures that are both beautiful and functional.

Despite its many benefits structural foam is still a relatively new technique, and some pool contractors may not be familiar with it. However, Nathan Giffin has been working hard to promote and teach the technique. Consequently, he’s been teaching pool builders how to build with structural foam.

This method of construction has been used in the past to create everything from bridges to theme park rides, but it’s also great for creating custom pools. With a little bit of knowledge and some practice, pool pros can learn how to use this technique to create custom outdoor features.

It’s clear that foam core construction is a promising technique for swimming pool construction. It is energy efficient, cost-effective, and durable. With experts like Nathan Giffin leading the way, it is likely to become more popular in the future.

Thinking Around Covers & Corners: A Pac-Man Style Spa

Published

Thinking Around Covers & Corners: With Todd Thomasson of Rockwater Farms

A client approached Rockwater Farm Landscapes & Hardscapes with a unique request: design a luxury backyard pool and spa that incorporated an autocover system. For many designers, that detail might have been a limitation, but for Todd Thomasson, owner of Rockwater Farm, it became the spark for something original. Rather than compromise the spa design, he treated the challenge as an opportunity to elevate the overall aesthetic. The result is a one-of-a-kind “Pac-Man” style spa that delivers both functionality and a striking focal point for the backyard.

A Philosophy of Unique Design

For Thomasson, every project begins with the belief that no two backyards should ever look the same. “We simply don’t build the same thing twice,” he explained. “Even if it’s another 20 by 40 pool, the backyard, the access, the elevations—all of it is different. Every time is the first time for us, and that’s what makes design exciting”.

This philosophy extends beyond pools. Founded nearly two decades ago, Rockwater Farm began as a landscaping company rooted in Thomasson’s background as a trained stonemason. Over the years, the company evolved to specialize in complete outdoor environments—pools, pavilions, fireplaces, outdoor kitchens, and landscape integration. That holistic approach ensures projects flow seamlessly, with one point of accountability and a vision that unifies all elements of the backyard.

Setting the Stage for Something Different

Like many of Rockwater Farm’s most memorable projects, this one began with a relationship. The homeowners had been long-time maintenance clients, trusting the company with their property care for years. When they purchased a new home in a growing neighborhood, they wanted more than just a functional backyard — they envisioned a place to entertain, gather, and enjoy with family.

The project unfolded in phases. First came a patio, outdoor kitchen, and pergola connected to the house — all designed and built by Thomasson’s team. But those elements were only part of a bigger dream. From the start, the homeowners knew a pool and spa would eventually complete the space. The question wasn’t if, but how.

The “Pac-Man” Spa

When it came time to plan the pool and reconcile the client’s desire for an autocover, Thomasson faced a design puzzle. The cover system required uninterrupted space at one end of the pool, which conflicted with traditional spa placement. Rather than forcing a compromise, he cut a quarter out of the spa and turned it into a design opportunity.

“I didn’t want the typical spa on the side of the pool that spills in. Those are dime a dozen,” said Thomasson. “We’re always asking: what haven’t we done, or what can we pull from different projects to create something unique? This became what we call a crow’s nest of a spa, perched up on the corner of the pool. Because of the shape, it ended up looking like Pac-Man”.

The cut-out serves multiple purposes. It creates a clean line for the autocover to function, ensures no one has their back to the pool—a safety consideration—and frames the water in a striking way. “By taking out that piece, we kept visibility of the water as a priority. Everyone in the spa is still looking across the pool, not away from it,” he explained.

A Balance of Safety and Style

Safety wasn’t an afterthought. For Thomasson, it was ingrained in the design process. He recalled his own childhood experiences as part of the inspiration: “I grew up with a pool. My mom was a school teacher, sitting on the deck with a whistle. That always stuck with me—the importance of seeing the water. It’s something I think about in every project”.

In this way, the spa design became both functional and symbolic. It respected the client’s need for safety, maintained visual oversight of the water, and at the same time became a distinctive element that elevated the project’s sophistication.

Material Selections That Complement the Design

The pool’s elegance extends beyond its shape. Every material was selected with care. Around the pool, Thomasson used marble decking with a sandblasted finish, chosen for its comfort and practicality. “It doesn’t get hot underfoot like flagstone, pavers, or even concrete. At the same time, it provides grip, so it’s safe as well as beautiful”.

The pavilion, angled to enhance views from the house, introduces a rustic counterpoint with Pennsylvania flagstone underfoot and heavy timber framing overhead. “Everything on this project is natural stone. We don’t really do pavers. I’m biased as a former stonemason, but I believe it’s a better product. It holds up, and it looks timeless,” Thomasson said.

The interior finish of the pool is a darker blue plaster, selected for both aesthetic and practical reasons. It reflects light beautifully and helps maintain water temperature, creating shimmering, reflective tones that change with the sky.

Transitioning Spaces Through Stone

Another intentional design detail was the use of contrasting materials at transitions. “I like step treads to be a contrasting material so they stand out. If you run travertine everywhere, bright sunlight can wash out those changes and someone could trip. By mixing materials, you get safety and visual definition, while also creating a sense of arriving in a new space,” Thomasson explained.

Bringing the Backyard to Life at Night

Bringing the Backyard to Life at Night

While the spa steals the show during the day, the backyard transforms into something even more dramatic after sunset. Thomasson integrated extensive lighting throughout the landscape, pavilion, and pool features. Solid granite fire bowls, gas-powered and glowing after dark, punctuate the scene. The pavilion’s fireplace adds warmth and atmosphere, while deck jets and bubblers with LED lighting create playful movement and vibrant accents.

“There’s just a lot of different activity that can happen out here. It’s not just a backyard—it’s a resort,” Thomasson said.

The Moment It All Came Together

For Thomasson, the true impact of the design hit during the project’s first photo shoot. “It really sank in when I was there at night. The lights were on, it was warm, everything came together. I just walked around and thought, ‘We actually built this. This looks awesome.’ It was one of those moments where you stop, take it in, and appreciate what you created”.

That moment of reflection underscores what makes Rockwater Farm distinctive: a blend of design ingenuity, craftsmanship, and respect for the client’s trust.

Beyond the Expected

What could have been a design obstacle—the integration of an autocover—became the genesis of one of Rockwater Farm’s most memorable projects. By embracing the challenge, Thomasson and his team produced something that is not only functional but also a signature piece of design. The Pac-Man spa represents more than a clever workaround; it reflects a philosophy of turning limitations into opportunities.

In Thomasson’s words, “Ultimately, you want something different in your portfolio. That’s how we approach design. It’s about pushing creativity while still serving the client’s needs”.

For Rockwater Farm, thinking around covers and corners has become second nature—and it shows in every detail of this unique backyard retreat.
