Building systems related to pre-cast concrete arise from the need of more efficient work. Pre-cast pieces ensure accuracy and, above all, speed when the time comes to assemble and adjust them. Today, we can assure variety and flexibility of the prototypes we build, which means we let out clients choose according to their project. Premoldeados Bertone has been doing this for years, and our experience will become, in the medium term, a common way to build.
