Building a pool with permanent formwork

The permanent formwork system was created and patented by Desjoyaux in 1978.

It is the concept of “active permanent formwork”, made of 0.25 m wide elements pressed from recycled polypropylene. This technology ensures a long service life and we give you a lifetime warranty on the structure. Special polypropylene panels are assembled into the sizes and shapes you want. The panels are reinforced and filled with concrete on site, which creates a self-supporting structure.

A screed is then applied to this base with a hose, and the pool is ready for the liner (membrane). The liner is fixed to the top edge with a fastening profile and covers the floor and the walls of the pool.

We build all our pools with this technology, and soon yours too…

Pipe-free filtration

How do you combine fast filtration, protection against leaks, water savings and efficient filtration? The whole difference is in the filtration system.

The system was inspired by outboard boat engines. It has no pipework, so there is no long and costly work on underground pipes, and no leaks can occur. The Desjoyaux filtration unit, either hung on the wall or built into the structure (your choice), consists of a filter compartment submerged below the water line, which also contains the jets, and a technical compartment built into the pool surround.
During filtration the water is drawn in by the skimmer onto a membrane with a porosity of 6 to 30 microns, and then returned to the pool through the jets. Thanks to this circulation, the whole volume of the pool is filtered through the membrane, above which the disinfectants sit in the pre-filter.

The result: no water goes down the drain, a greener way to filter, and clear, clean water.

This filtration technology is also a great solution when renovating or rebuilding a concrete pool. A counter-current and salt chlorination can be added to the filtration unit, and a light is included as standard. And don't worry about the construction work: we won't harm a single blade of your lawn.
