ABSTRACT
The Cadiz Theatre represents an archaeological site of special cultural interest as it is considered to be the oldest and the largest of the Iberian Peninsula. Its proximity to the sea and to one of the main streets of the city promotes the acceleration of the degradation phenomena.
Thus, the objective of the work has been the application of a consolidant to minimize the action of the atmospheric agents. Prior to the in situ application, preliminary laboratory tests have been performed including: XRD, XRF, colorimetric, hydric and mechanical analysis, in order to characterize the stone substrate. The same analysis were repeated, after the application, in order to evaluate the compatibility and the effectiveness as consolidant product.
In accordance with the laboratory results, the consolidant treatment was applied in situ on the Theatre. The in situ analysis highlighted an increase in the grains cohesion as well as a significant reduction of the water absorption.
