Why is it necessary to cover the concrete slab under the pool with polystyrene?

When planning the construction of a swimming pool, it is essential to ensure proper preparation of the foundations that will serve as a solid base for the pool structure. One key element is the concrete slab, which plays a stabilizing and leveling role. However, it’s important to remember that concrete slabs can have minor irregularities that require leveling. For this purpose, the use of an insulating material such as polystyrene is recommended. In today’s article, we will discuss the reasons why it is worth laying a concrete slab with polystyrene.

Leveling irregularities:

Concrete slabs, although solid and durable, can have certain imperfections, such as minor irregularities. These irregularities can affect the stability of the pool and be unfavorable for its structure. Laying a concrete slab with polystyrene allows for the leveling of these irregularities, providing a more even and stable foundation for the pool.

Protection against damage:

Without the use of polystyrene, the pool’s bottom slab could be subject to damage over time due to friction with the concrete. Movement and friction between the concrete bottom and the pool structure can lead to damage that could potentially result in water leaks or other structural problems. Polystyrene acts as a protective layer, reducing the friction between the pool’s bottom and the substrate and preventing damage.

Additional thermal insulation:

Polystyrene, in addition to its leveling and protective functions, also provides additional thermal insulation for the pool’s bottom. This is especially important if you plan to use the pool year-round. Polystyrene acts as a thermal barrier, helping to maintain the water temperature at the desired level, which can lead to lower costs associated with pool heating.

Summary:

Laying a concrete slab with polystyrene has several benefits. Firstly, it helps level minor irregularities, creating a more stable foundation for the pool. Secondly, it protects the concrete from damage that can occur due to friction with the concrete. Finally, it provides additional thermal insulation, contributing to effective temperature maintenance in the pool.

In conclusion, laying a concrete slab with polystyrene is an essential step in pool construction that affects its durability, stability, and energy efficiency.
