Diffazur, Europe’s leading manufacturer of reinforced concrete pools, has been building custom private and public pools since 1974 and has 50 years of experience and expertise in pool construction and hydraulic performance.

As Europe’s leading brand of reinforced concrete pools, we have built our reputation on solid workmanship. With over 45,000 concrete pools built, our expertise is recognized and our signature often copied. We were indeed the first to launch free-form concrete pools, submerged decks, overflow pools, mirror edges or lagoon style and we are still at the forefront of innovations and style creations.

Diffazur is the leader and key player in the construction of reinforced concrete pools and spas using an exclusive technique : dry shotcrete.


Reliable, proven and approved, the dry shotcrete technique (gunite) is the guarantee of a safe investment. It is also the only concrete pool and spa construction technique that can be adapted to all types of land and access configurations.

This construction technique, exclusive to Diffazur in France, makes it possible to build true one-piece reinforced concrete pools. Your pool is built in one piece like a reinforced concrete shell for a long-lasting and durable pool.

This technique is at the heart of our swimming pool constructions but is also used in the construction of engineering structures such as dams or tunnels. This technique is recognized in the construction industry for its solidity and flexibility because it allows the construction of the most complex shapes. Technically, the concrete is sprayed at 500km/h in a single projection, forming a homogeneous and ultra-resistant concrete shell.

Solidity, flexibility and creativity are the strengths of our one-piece reinforced concrete, offering total freedom of construction for your pool.

Freedom, choice

At Diffazur you will not find industrialized models but real custom-made concrete pools or spas that meet your desires and the specificities of each individual project. All styles, all choices, all finishes, custom-built, Diffazur pools and spas fit all budgets and integrate perfectly into your environment.

Diffazur has revolutionized the French market by creating numerous pool styles: freeform, submerged or semi-submerged decks, overflow pools, mirror edges, lagoon pools, nature pools … but above all Diffazur adapts to your style and builds real custom pools. There are as many Diffazur pool styles as there are customers.
