The internal and external façades of the Royal Palace of Caserta have been restored in order to allow the safe use of all areas and the improvement of the Vanvitelli Complex, which was showing signs wear and tear. The interventions carried out by Cobar SpA focused on part of the façades, with cleaning and consolidation operations. New technological advancements, involving 3D laser scanning, have reproduced a realistic model of the building. This has vastly helped in the analysis and information gathering phases, which were necessary to carry out proper consolidation interventions and correctly monitor all progress.

Cleaning operations were carried out on the stone facings with the following techniques: application of ammonium carbonate gel compresses and subsequent washing, and on the false plaster surfaces located in the corner caps of the inner courtyards; plastering, soaking and consolidation of the existing material, reconstruction of the joints in order to recreate the lost artistic style. The consolidation operations on the stone elements were carried out with different methods: mapping and cataloguing the surfaces, such as fissures and cracks, allowed us to create and study the use of special reinforcement bars, different in material and diameter, to be applied according to element size. The damaged stone sections were reconstructed and replaced with elements of the same type made in a laboratory, with material coming from quarries similar to those used for the original material.
