We're starting with the structural flooring

For that we're using CUPOLEX, an aereated structural flooring system made of recycled plastic domes. They're rapidly and easily interconected forming a self-bearing structure suitable to admit the concrete pouring to create a slab of variable thickness, resting on pilars at the centre distance of 56 cm and with under-slab cavities.

This cavities give the flooring structure ventilation in all directions protecting it against moisture and helping disperse the harmful gas "Radon" to the outside of the building. Breathing high concentrations of Radon has been known to cause lung cancer. Thus, Radon is considered a significant contaminant that affects indoor air quality. Acording to the World Health Organization radon is the second most frequent cause of lung cancer worldwide.
