Swimming Pool Construction

Rapid construction combined with enduring reliability and the freedom to create any shape of pool you like! Our Active Permanent Casing structure gives you complete freedom to build with complete confidence.


The Desjoyaux casing structure concept

The freedom to create any shape or size pool is determined by assembling a series of panels that form the structure of the pool Active Permanent Casing. This exclusive process ensures that the pool is strong and long-lasting, while offering great creative freedom in terms of its design.

The installation technique maximises the pool's service life by casting a reinforced concrete bed-slab and by installing the reinforcement and casting the side-walls in a single operation. Your Desjoyaux pool is a rot-proof, single-piece self-supporting structure.

The safety of our production process and the sturdiness of the Active Permanent Casing are monitored by Bureau Veritas.

Build Process

  • The panels are reinforced and cast in concrete on site in a single operation.
  • This creates a free-standing, self-supporting single-piece structure.
  • Once concrete has been poured, a smooth screed is created on the pool's reinforced concrete base.
  • The pool is then ready to be fitted with the liner. This is fixed in place using a liner lock that covers the base and walls attached to the top of the casing.
  • Bureau Veritas monitor the production process and the sturdiness of our active permanent casing structure.
