Creation of a concrete elevation wall, of the total thickness, net of external finishes varying from 30-35-40-45cm, made with an on-site casting of concrete (resistance class Rck 30N / mm2 and consistency S4 or as required by relationship of reinforced concrete structures), carried out in a single solution (generally up to a height of 3.00-4.00-5.00m) with an average thickness of 16.5 - 21.5cm in a self-supporting formwork that will remain as an insulating element of the wall itself giving it a thermal transmittance value U (depending on the chosen insulation) equal to 0.22-0.16-0.13 W / mqK (constant over time). The formwork will consist of modular formwork elements, 30cm high, made up of two sheets of different thickness (internal thickness equal to 62mm, external thickness chosen from 73-123-173mm) in expanded polystyrene Neopor® (eps with improved conductivity ), self-extinguishing with high density, joined by spacers in galvanized steel sheet incorporated in the polystyrene during the molding phase. The formworks will be dry laid up to the floor height. Simultaneously with the laying of each course of formwork, the horizontal reinforcing bars will be laid in the spacer housing (as per structural calculation). Once the floor height has been reached, the vertical reinforcing bars are lowered from above (as per structural calculation). In the last phase, the concrete will be cast inside the formworks previously shored with special equipment to ensure verticality.
