The decay of stone and brickwork is a serious problem in many civic and commercial buildings as this leads to physical loss of the outer fabric, dampness and concerns about safety. The problem of stone decay is also very apparent in the deterioration of historic architecture and masonry.
Acid rain and pollution are the major causes of the decay. The erosion of our heritage and escalating costs of restoration and replacement has focused attention of arresting these problems. In most cases the use of preservatives and consolidation are the only available methods of retaining the history of our building facades and architecture.
Causes of Decay in Masonry
Loss or erosion of the cementing matrix in the substrate by acid attack
Disruption of the inter-granular bonds in the substrate by increased tensile stresses caused by salt crystallization
Defence Against Attack
Any preservative applied in conservation work must fulfill two important criteria by:-
Replacing the internal cementing matrix to strengthen the friable pore structure
Prevent the migration of soluble slats, without affecting water vapour permeability, to reduce the effects of salt crystallization
