FAQS

How is a Domo built? The PVC membrane is secured to its foundations and then pressurised. Polyurethane foam is then sprayed into the inside of the membrane. A combined process is made of gradually fitting the steel framework and spraying the concrete until the reinforced concrete structure is completely built. The PVC membrane remains the outer finish.

How long does it take to build? The Domo shell structures require a short construction period of between one and four months.

Is it cheaper than other constructions? Yes, its cost is competitive with conventional constructions.

In which cases is it most recommended? For large spans and to keep the inside completely isolated from the outside.

Is it completel airtight? Yes, the outer sheet is a 1 mm thick PVC membrane and the first inner sheet is made of stiff polyurethane resin with a thickness of no less than 20 mm. Both sheets make the structure completely airtight.

Are technical and acoustic conditions improved? Yes, they are improved thanks to the polyurethane resin sheet and to their geometry.

Can gaps be made in these  structures? Yes, gaps of the required size and geometry can be made..

Are special foundations required? No, the double curvature monolithic surface has a better performance with regard to specific and distributed loads.

Can point loads be withstood on the outside? Yes, greater than those on structures with different geometries.

How long do they last? Greater durability than any reinforced concrete structure is guaranteed, wih greater performance with regard to earthquakes.
