The construction of Diffazur pools follows a very precise technique that makes us exceptional.

Which structure for my pool ?

Your reinforced concrete pool designer Diffazur uses a powerful construction technique : the Gunite. This technique, used during the construction of your pool, will allow you to obtain a durable structure over time. This is the price of peace of mind !

Construction of my pool

Description of the Gunite

The Gunite is a dry method of spraying concrete. A pipe propels the concrete at 500 km/h on the reinforcement of your future pool. This way, the walls and bottom of your pool form a monobloc, non-deformable shell with a perfect seal.

The Diffazur plus

  • The Gunite allows you to build the most complex shapes ! The advantage of this choice of construction is the ultra-customization of your pool (submerged deck, balneo bench…).
  • This technique also allows you to adapt to the different access constraints of your land as well as to all types of pools : in-ground or semi in-ground, in the continuity of a raised terrace or on the ground.

The stages of construction

Would you like to know how Diffazur builds your watertight monobloc reinforced concrete pool ? From the choice of the location on your land to the launching of the pool, follow the work of the Men of Art step by step, accompanied by your works manager.


The ground marking of your pool project will allow us to start the construction of the pool in your garden. This is the first meeting with a site technician. He will give you the tone of your dream project : site explanation, planning…


The earthwork is the first physical step in the construction of your pool. It consists in digging a hole in your land. Its price depends on the nature of your soil (limestone, rocky …) and the quantity of earth to evacuate. This place will welcome your future watertight monobloc reinforced concrete pool. The earthwork of your Diffazur pool is crucial. It ensures the solidity and stability of your pool over time.


Your type of pool takes shape ! The reinforcement is the support on which your pool will be projected. A specific reinforcement, the chainage, is put in place at the top of the lock walls. The concrete applied will be reinforced with steel or fibers that strengthen the structure. It is a work of goldsmith realized by our Men of Art.


Plumbing is essential in the construction of your Diffazur reinforced concrete pool and requires real expertise. It is important to know that the water in a pool operates in a closed circuit, from the pool to the technical room (wooden shelter, kit or masonry or rock Diffaroc), and vice versa. This perpetual circle of water is made possible by a system of connecting pipes and embedded parts such as skimmers. This installation circulates the water in your pond through a filtration system that ensures good water quality. Plumbing connections also allow for the installation of water treatment, purification and heating equipment. Pool accessories that can sometimes be added at a later date, since all Diffazur filtration systems are upgradeable.


At this stage of the work, the pools generally become more concrete in the eyes of our customers. If you want to know more about our shotcrete technique, find more information here !



This stage of the construction of your pool is one of the most delicate. It requires a great deal of rigor and concentration to ensure that the result is perfect.
