Why Lime Mortar is Essential for Stone Buildings
The use of cement-based mortars on historic stone buildings is one of the leading causes of masonry failure. Cement is rigid and impermeable, trapping moisture within the stone and leading to "spalling" (surface crumbling) and damp issues.
At Architectural Stone Conservation, we specialize in the application of traditional lime mortar. Unlike cement, lime is flexible and "breathable," allowing moisture to escape through the joints rather than through the stone itself. This is critical for the long-term health and structural stability of any historic building.
