The Waterpolo Arena, built for the 2012 games, is a temporary structure which will be completely demolished after the competition. The building clad in Précontraint 1002 S2 NPP* Silver is distinctive due to a sloping inflatable roof, which undulates like a breaking wave.
The building’s unsupported span of 54 m x 124 m required a strong, flexible, lightweight material. It also had not only to meet the building’s structural demands during operation, but also to stand up to dismantling, while maintaining structural and aesthetic integrity in view of its re-use.
Précontraint 1002 S2 NPP composite material was a natural choice in this context.
Large spans of 54 m long x 10 m wide double membrane cushions were made up and inflated with air at a pressure of approximately 300 pascal before being installed to form the roof. The advantages of these inflatable cushions are twofold: to curtail the condensation phenomenon and to form the gentle slope of the inclined roof.
Inside the building, the opaque version of Précontraint 1002 S2 NPP* composite membrane creates the luminous environment required for high-definition recordings and broadcasts.
Acoustically, the sound reverberation effects inherent to aquatic centres were reduced by installing 1,000 m2 of Soltis 99-1 NPP*.
