The purpose of restoring façades is to protect buildings from the damages caused by a constant exposure to atmospheric agents. The success of the restoration depends basically on the skills of its executor, who must be capable of identifying, establishing and solving the problems which an exposed surface may pose. Today, materials used in masonry are technologically advanced and allow the recovery of any kind of surface in full respect of the hygroscopic properties of the building. We are therefore capable of: reconstructing areas of degraded façades, protecting concrete risers, corbels and parapets from deterioration, (mainly caused by smog, acid substances and rain water), renovating ancient decorated façades with plastic coating, plastering the façades of restored buildings, modifying internal cladding, polishing and waterproofing façades.
