How exactly does an overflow coping swimming pool work?

The modern overflowing pool system is prominent in the most current projects. The technical and design evolution of special ceramic pieces has enabled architects and construction professionals to choose this system, whose main feature is that water flows over the edge, creating a continuous aesthetic effect, where the pool water is constantly renewed.

Find out  how exactly does an overflow coping swimming pool work?

The the overflow coping system offers complete integration between the interior and exterior of the pool, creating a visually harmonious space. To achieve this striking finish, it is essential to use specially designed ceramic pieces developed specifically for this system. In addition to fulfilling their functional roles in lining and filtration, these elements are becoming increasingly important in terms of aesthetics.

Exagres includes in its catalog a wide variety of collections with all the special pieces required in an infinity pool, including ceramic grates and overflow edges, as well as different finishing options such as wood, stone, marble, or cement.

But… how does an overflow pool work?

Operation

In overflow pools, water constantly flows over the edge, creating the optical illusion where the waterline blends seamlessly with the horizon. To achieve this effect, it is essential for the pool water to remain consistently clean and balanced at all times.

A diferencia de las skimmer pools, in which the water bounces of the sides, an overflow system keeps the water in constant motion: the overflowing water passes into the channel that surrounds the pool through a ceramic grid; this water moves on to the balance tank and then the filter to be later returned to the pool after filtration.

The various construction options for overflow pools include the infinity and lake effect varieties, genuine visual spectacles in terms of aesthetics and constructive design

The Infinity Pools and lake effect ones are the most common of the overflowing system. In the case of the former, these achieve total integration with the environment, in whose construction the key element is the swimming pool edge, which is below the water level, allowing water to cascade constantly. As for the lake effect ones, the most important piece is the ceramic grille, through which water enters directly into the channel and purification system.

Overflow pool scheme

An infinity pool requires precise execution and specific materials that ensure the proper functioning of the overflow. The following technical scheme shows the structural and ceramic organization of the overflow crowning system by Exagres:

• Ceramic overflow edge : key piece in the crowning that allows uniform overflow of water towards the grid.
• Ceramic grid : fitted between the edge and the gutter, allows water to pass in a controlled manner to the collection system.
• Perimeter channel hidden: internal structure that collects overflow water and directs it towards the compensation tank.
• Internal Cove: facilitates cleaning and prevents dirt from accumulating in hard-to-reach corners.
• Overflowing angle: solves exterior corners guaranteeing continuous aesthetic flow without interruptions.
• Grid angle: ensures the passage of water flow even in interior corners, maintaining uniform overflow

Among the various solutions for overflow pools, the infinity and lagoon-effect types stand out as the most striking, both for their aesthetic value and their construction complexity.

Filter system

An  infinity pools are the cleanest pools; any leaf or dirt that falls into the water will disappear over the edge, preventing it from reaching the bottom and accumulating or decomposing. Thanks to its characteristic filtration system, the water is completely renewed constantly and in a short period of time. Thanks to this, it is possible to keep the water always clean and with a crystalline appearance.

One of the most visible and relevant components in this type of installation are the edges of infinity pools. These pieces not only fulfill an aesthetic function, but also a technical one, by allowing water to flow towards the grating.

Exagres offers overflowing edges in various sizes and finishes —wood, cement, stone or marble—, all with anti-slip finish C3 · ≥R11.

In addition, the pieces are precision-ground to ensure a metric-perfect fit and professional installation. Internal, external angles, and modular grates allow aesthetic continuity even in pools with corners or curves.

Thanks to this variety of ceramic solutions, it is possible to adapt the design to any outdoor environment, whether minimalist, rustic or contemporary.
