The precast panelled walls are two plates of reinforced concrete with a latticework that forms the exterior parts of the traditional walls. The different types of walls can be carried out by either placing vertical reinforcement on site or later spilling concrete, independently of their width and height its quick and safe assembly and perfect exterior finishes make it a very interesting element for different units of work as we avoid not only the manipulation and rental but also the cleaning of the metallic formworking.
