Round composite pools

Round composite pools distribute the water’s hydrostatic pressure evenly around the entire perimeter, eliminating the need for steel beams buried in the ground.

This circular geometry offers key mechanical and logistical benefits:

• No need for deep excavations for omega-shaped tie-rod trenches.
• Faster assembly thanks to symmetrical tongue-and-groove panels that fit into vertical aluminum profiles.
• Greater resistance to deformation around the perimeter without requiring protruding external supports.

To renew the watertight lining after years of use, simply replace it with a compatible component such as the Gre blue liner Ø 350x120 for round pools, leaving the structural wall intact.

Yes, building a completely flat and level concrete slab is strictly required to ensure stability and maintain the warranty for round composite pools.

Composite transfers tons of vertical and lateral thrust to the ground. An uneven or compacted-earth surface will give way over time, causing the plastic resin panels to come apart and the liner to tear under tension. Manufacturers require a reinforced concrete platform at least 15 centimeters thick, perfectly smoothed and free of loose gravel that could puncture the watertight base.

Composite requires no annual treatment with oils, varnishes, sealants, or fungicides, unlike natural wood, which cracks and rots without constant maintenance.

Made from a composite of recycled wood fibers and synthetic polymers, it withstands direct sunlight, chlorine, and constant moisture without splintering. To preserve the surface, simply use neutral soapy water and gently brush it at the start of the season to remove any accumulated dust or environmental dirt.

Access to this type of elevated pool is managed using double-access ladder systems that prevent children from entering accidentally when the pool is unsupervised.

They are normally equipped with an integrated exterior ladder made of composite or non-slip resin, combined with an interior stainless steel ladder. For compatible above-ground structures, sturdy solutions such as the Gre ladder for above-ground pools, mod. AR11680 allow the exterior steps to be removed or locked at the end of the swimming session, meeting preventive safety standards for private premises.

Round composite structures require a sand filtration unit with a flow rate usually sized between 4 and 6 cubic meters per hour, depending on the total volume.

The filtration process requires specific components integrated into the pre-punched walls:

• A wide-mouth skimmer with a swinging weir that captures floating debris from the water’s surface.
• Adjustable return nozzle that creates a circular current in the pool to direct sediment toward the intake.
• Pump with prefilter connected to a tank of silica sand or glass filter media to trap microscopic impurities.

Complete hydraulic components such as the Skimmer + AR100 return nozzle ensure a watertight seal around the panel cutout and prevent unwanted leaks in the closed circuit.

For a round composite pool with a diameter of 410 cm, a minimum clear perimeter area of 500 cm x 500 cm must be reserved in the yard.

It is essential to leave a clearance of at least 45 to 50 centimeters around the entire pool shell to allow for assembly of the metal corner pieces, installation of the winter cover, and placement of the filtration equipment. Keeping this space clear also makes routine exterior cleaning easier and ensures that there are no walls or branches casting continuous shadows or dropping debris onto the water.

The composite pool shell is fully compatible with salt chlorination systems because its synthetic walls are immune to corrosion from sodium chloride.

However, special attention must be paid to the auxiliary components. The mounting profiles are usually made of anodized aluminum with high galvanic resistance, but it is essential to connect a dedicated grounding point for the pool water. This measure prevents galvanic currents from damaging the stainless steel ladder or the connecting hardware, extending the installation’s service life for years.
