Fiber-reinforced polymer (frp) composite swimming pools and method of constructing frp composite swimming pools

A method of constructing a swimming pool, the method comprising:

• applying a plurality of gelcoat layers to a mould for forming the swimming pool in multiple stages;
• laminating a thin protective layer of a fiber-reinforced polymer composite and a polymeric material over the plurality of gelcoat layers;
• applying a thick structural layer of the Fiber-Reinforced Polymer (FRP) composite and the polymeric material over the thin protective layer forming a basin structure having a bottom surface and a plurality of walls extending upwardly, defining an internal cavity for containing water;
• affixing a framework externally to the basin structure, the framework having a plurality of support assemblies positioned exterior to the basin structure, wherein the plurality of support assemblies includes a stiffened element provided on one or more edges and corners of the basin structure and extending across a top periphery of the basin structure, wherein the stiffened elements include
• one or more structural sections arranged one over the other, and
• layers of the fiber-reinforced polymer composite, the polymeric material and a gelcoat applied over the one or more structural sections;
• laminating a finishing layer of the FRP composite and the polymeric material over the basin structure and the framework;
• applying a sealing resin over the basin structure and the framework to integrate the basin structure and the framework forming a pool structure;
• allowing the pool structure to cure within the mould for a specified period;
• and
• extracting the cured pool structure from the mould.
