Record-breaking swimming pool in Sardinia
The secret behind RENOLIT ALKORPLAN’s ultimate luxury
The ultra-luxury swimming pool built in Porto Cervo is one of the most iconic projects ever realised in Sardinia: a one-of-a-kind Y-shaped pool with a glass infinity edge, suspended surfaces and a RENOLIT ALKORPLAN TOUCH Sublime reinforced membrane lining, chosen to ensure absolute waterproofing, architectural freedom and an uncompromising aesthetic impact.
This project demonstrates how, in contemporary luxury real estate, the reinforced membrane is no longer merely a technical solution, but a genuine tool for design and property enhancement.
Why is this luxury swimming pool in Porto Cervo considered a unique project in Sardinia?
This swimming pool is not merely a functional feature, but the architectural centrepiece of the entire villa. From the design stage onwards, the pool was conceived as a visual and structural extension of the house, integrated into the central courtyard and in harmony with the landscape of the Costa Smeralda.
The distinctive features of the project include:
- A highly customised Y-shape
- A glass front overflow edge with a ‘suspended water’ effect
- Structural glass in the middle of the pool to provide natural lighting for the lower spaces
- Significant structural cantilevers on the lower level
- RENOLIT ALKORPLAN TOUCH Sublime pool liner
How was such a complex, ultra-luxury Y-shaped swimming pool designed?
The Y-shape stems from a specific architectural requirement: to create a swimming pool that was visually sculptural yet functionally central to all areas of the villa. What technical challenges does a Y-shaped swimming pool present?
An unconventional geometry presents numerous challenges:
- Continuity of waterproofing along complex curves
- Management of structural movements in reinforced concrete
- Integration of structural glass without weak points
- Perfect sealing in the overflow areas
In this context, traditional materials such as tiles, mosaics or rigid resins would not have guaranteed long-term reliability.
Why was the RENOLIT ALKORPLAN reinforced membrane a key factor in this project?
The choice of the RENOLIT ALKORPLAN reinforced membrane was not based on aesthetics, but on strategic technical considerations.
“This swimming pool has a significant overhang on the lower level. Only a reinforced membrane could partially accommodate the movements of the reinforced concrete structure and ensure long-term durability.”
Gianluca Bo – Project Manager
What technical advantages did RENOLIT ALKORPLAN offer compared to other liners?
Key advantages:
- Guaranteed waterproofing even in the presence of micro-movements
- Complete continuity on complex shapes
- Compatibility with glass infinity systems
- Welded, joint-free surface
- Easy maintenance over time
How important is aesthetics when choosing a lining for luxury swimming pools?
On the Costa Smeralda, a swimming pool is much more than a technical installation: it is about design, property value and status.
“On the Costa Smeralda, the swimming pool is one of the most important features of a home. A home with a swimming pool is something else entirely.”
Antonio Spanu
Why was RENOLIT ALKORPLAN TOUCH Sublime chosen for this swimming pool?
RENOLIT ALKORPLAN TOUCH Sublime was selected for its natural textural effect and its ability to transform water into an emotional element.
How does the TOUCH collection change the appearance of the water? The end result is deep, luminous and natural-looking water, in harmony with the architecture and the Sardinian landscape.

The front glass overflow was achieved through meticulous design and the selection of the RENOLIT ALKORPLAN reinforced membrane, an essential solution for managing such a technically delicate element. The reinforced membrane allows for continuous welding against flanges and profiles, drastically reducing critical points of infiltration, adapting precisely to the tolerances of the structural glass and ensuring a long-lasting seal, even in the presence of structural movement. As Project Manager Gianluca Bo points out, traditional materials such as tiles or rigid cladding would not have offered the same guarantees of reliability and durability in a project of this complexity. della struttura. Come sottolinea il Project Manager Gianluca Bo, materiali tradizionali come piastrelle o rivestimenti rigidi non avrebbero offerto le stesse garanzie di affidabilità e durata in un progetto di questa complessità.
The entire swimming pool is the result of a multidisciplinary collaboration of the highest calibre: the construction of the pool was overseen by Krealpool with Luca Cattaneo as the contact person, whilst the installation was entrusted to AB Piscine with Alessio Budelli, who highlighted the importance of the material’s workability, particularly in conditions of intense sunshine and high temperatures. Project coordination was overseen by Gianluca Bo, with Antonio Spanu as Site Manager and the essential technical support of Samuele Petrini, Technical Manager at RENOLIT ALKORPLAN. In a luxury project such as this, the installation is just as crucial as the material itself: the reinforced membrane guarantees total waterproofing, adaptability to complex shapes, aesthetic continuity and speed of installation, making it possible to renovate the pool in just a few days without invasive demolition work.
Frequently asked questions about the RENOLIT ALKORPLAN reinforced membrane:
How long does a reinforced membrane last in a luxury private swimming pool? If correctly installed and maintained, over 20 years.
Is it only suitable for modern swimming pools? No. It is perfect for both new builds and renovations of existing swimming pools.
