The project is conceived as an intervention to stop the pathologies that currently affect the outer envelope of the retaining wall that gives access to the New Tower. Two types of pathologies have been detected that could be classified as serious:
Physical pathologies: This type of on-site failure refers to loss of material, poor behavior in physical requirements and deterioration due to misuse of the same. Thus, in the restoration that is the object of this project, the following have been detected: loss of mortar, loss of volume of stone elements, oversizing of elements that have caused the collapse, loss of stability due to overloads and conditions derived from the collapse due to retraction of fillings.
Chemical pathologies: This type of pathology refers to those generated by exothermic chemical reactions (radiation, photosensitive parasites, etc.) or endothermic (breaking the internal structure of construction elements). In the restoration object of this project, the presence of plant parasitic agents, chemical reactions derived from poor stone quality or by reaction with elements of environmental pollution have been detected. The chemical decomposition caused by sandblasting, black crust, peeling or filtering have caused the poor state of conservation, especially in localized areas such as humid areas (lower parts of the wall, areas peripheral to the flower beds, etc.).
The project is conceived as a search for solutions to each of the pathogenic agents, both chemical and physical, by incorporating new physical elements and treating the chemical ones.
