Deterioration When water evaporates, Extensive crack of the Moss adheres to the surface, Mold adheres to the surface
characteristics salts precipitate, and the facing, leaving the internal trapping water and eroding of the wall and darkens in
surface whitens blockwork exposed the stone masonry footings color
