How Desjoyaux Pools Are Built, Start to Finish

A Different Approach to Building a Pool

Not all inground pools are built the same way. While many traditional pools rely on block walls, steel panels, and extensive underground plumbing, Desjoyaux pools follow a different system—one that focuses on strength, efficiency, and long-term reliability.

At the core of the process is a permanent casing wall structure combined with a monolithic concrete pour and an integrated filtration system. The result is a pool that is built as one solid unit rather than a collection of separate components.


From Design to Excavation

Every project begins with design and layout. This is where the size, shape, depth, and features of the pool are determined. Whether it’s a simple rectangular layout or a fully customized backyard design with patios and outdoor living features, this stage sets the foundation for everything that follows.

Excavation For Pool Construction

Once finalized, the pool area is excavated to match the exact dimensions of the design. Proper excavation is critical—it ensures the structure sits correctly and allows for precise elevation and grading.

Building the Structure

After excavation, the Desjoyaux wall forms are installed. These are made from recycled polypropylene and are designed to stay in place permanently, unlike traditional temporary forms. The system is assembled to match the exact shape of the pool, creating the framework for the structure.

Steel reinforcement is then added throughout the walls and floor. Rebar and mesh are tied together to strengthen the structure and create a fully bonded system. This step is what gives the pool its long-term durability and resistance to shifting or cracking.

Before any concrete is placed, the walls are carefully aligned and braced to ensure everything is level, straight, and structurally sound.


One Solid Concrete Shell

One of the most important steps in the process is the concrete pour.

Unlike some pool builds where the floor and walls are done separately, Desjoyaux pools are formed into a single, monolithic concrete structure. The wall forms are filled with concrete while the base is poured, creating one continuous shell.

This method increases strength, improves longevity, and performs especially well in climates like New Jersey where freeze and ground movement can be a concern.


Integrated Filtration System

Another major difference is the filtration system.

Desjoyaux pools use an integrated filtration unit instead of a traditional system with underground plumbing lines. By eliminating long pipe runs, the system reduces the risk of leaks and simplifies maintenance over time.

The filtration is built directly into the pool structure, making it both efficient and easier to manage for homeowners.


Bringing the Pool to Life

Once the structure is complete and cured, the interior finish is installed. This is where the pool begins to take on its final appearance.

From there, the surrounding area is completed. Coping is installed along the pool edge, followed by concrete or paver decking. This is also the stage where patios, fire pits, outdoor kitchens, and other features come together to create a full backyard environment.

What started as an excavation now becomes a complete outdoor living space.


Final Setup and Startup

With construction complete, the pool is filled and the system is started up. The filtration unit is tested, water chemistry is balanced, and everything is checked to ensure proper operation.

At this point, the pool is ready to be used—and more importantly, enjoyed.


The Bottom Line

The Desjoyaux construction process is designed to create a stronger, more efficient pool by combining a permanent wall system, reinforced concrete structure, and integrated filtration.

Instead of relying on multiple separate components, the entire pool works as one solid system. That approach not only improves durability but also simplifies long-term maintenance.
