Rectangular shell pool – another alternative

What is a rectangular shell pool?

Definition

The structure of this type of factory-molded pool is made of polyester. The polyester shell pool is delivered in one piece to the site, ready for installation.

Facility

Once the excavation is complete, the polyester shell pool will be delivered to the site to be positioned on a gravel bed. The coping stones will then rest on masonry. This quick installation allows customers to benefit from an in-ground pool.

Disadvantages

It is important to keep in mind that a shell pool is a lightweight structure due to its concrete-free structure. The polyester shell, which provides both the structure and waterproofing for the pool, is delivered and installed on a terraced site in a single operation.

The stability of the pool in the face of ground movements remains less reliable than a pool whose structure and bottom are reinforced and cast. After-sales service intervention on a shell structure can also be tricky and must be done quickly (the shell being the structure and waterproofing of the pool).

Another alternative: the modular swimming pool

For customers who want to opt for a heavy structure without going through the "traditional" concrete block or sprayed concrete pool, modular pools remain the best alternative.

Definition

As its name suggests, a modular pool is made up of modules or panels pre-fabricated in a factory. They are then assembled together on site, then reinforced and filled with concrete. A liner then seals the structure.
The leader in this concept in France is the Piscines Desjoyaux brand, which filed a patent in 1978: active permanent formwork. The polypropylene panels (now recycled) are assembled and then reinforced. Pouring the slab and panels in a single operation makes the pool a rot-proof, single-piece, and self-supporting structure.

Advantages of the modular swimming pool

The modular swimming pool undoubtedly combines all the advantages of the different processes existing on the swimming pool market:

– Solidity of construction: modular swimming pools are classified as heavy structures since the formwork is reinforced and filled with concrete.
– Installation: Generally available in kit form, these pools can be installed by customers with masonry expertise. They come with a very detailed assembly guide allowing for installation in accordance with the brand’s specifications. Find out the 6 steps for building a Desjoyaux pool .
– Attractive price-quality ratio: A factory-produced structure, quick on-site assembly for controlled labor costs. A filtration system located at the foot of the pool which avoids the construction of a remote technical room (which generally includes the sand filter) as well as the pipes connecting the pool to the filter.

– Customization for a unique pool: This type of structure allows great freedom in terms of shapes, dimensions and depths. Each client can also choose the means of access that suits their environment and desires: stairs added to the side or end of the pool, internal corner stairs, full-width internal stairs, submerged beach, etc. Finally, the choice of the color of the liner and the edges will finalize the identity of the pool.
– Any after-sales service request on one of the components of the swimming pool (filtration unit, liner, etc.) will have no impact on the other components (example: an intervention on the liner has no impact on the structure of the swimming pool)

Disadvantages

Like any construction project, the installation of a modular pool depends on the schedule of the contractors and the weather conditions. In other words, during periods of high demand, the pool installation time will necessarily be affected.
