This typology is the cheapest available. It is the best solution for those who desire having a private pool but can’t manage to construct the classic ones described before. Realization costs are lower and construction times shortened. Despite being pre-fabricated structures, this type of pool are made starting from a concrete base followed by an overlapping of masonry walls, which are made with perforated concrete blocks, until you obtain the right height. The final step is that of the installation of the reinforced PVC, so as to thoroughly waterproof the pool structure.
