What are the Primary Obstacles to Preserving Facades Made of Natural Stone
Historical and contemporary architecture favor natural stone facades for their attractiveness and durability. The distinct qualities of the material and the environments to which these facades are exposed make maintenance difficult. Maintaining the structural and aesthetic integrity of natural stone facades requires an understanding of these difficulties.
Cycles of Freezing and Thawing
The influence of freeze-thaw cycles is one of the biggest issues in preserving natural stone façade. Water that seeps into the stone and freezes causes it to expand, resulting in tiny fissures and eventually serious structural damage. Repeated freeze-thaw cycles may degrade stone in locations with frequent temperature variations.
Acid Rain and Pollution
Natural stone facades in urban settings are subject to pollution and acid rain, which may lead to chemical degradation. Acidic chemicals are created...
