Experts agree that the durability of masonry depends primarily on its resistance to water penetration. Water damage may include corrosion, deterioration, dimensional damage, efflorescence, freeze-thaw spalling, staining, damage to interior finishes, and, ultimately, structural failure.
It is well established that water will penetrate a single wythe masonry wall. Even masonry walls constructed according to standard ASTM requirements will permit water penetration through the brick-mortar interface of head and bed joints. Chimney and wall design, material selection, and quality of construction are important factors in determining resistance to water penetration in masonry chimneys or walls. Understanding the causes and mechanisms of water penetration in masonry will enable technicians to better diagnose and solve problems before severe damage occurs.
This guide provides a quick overview that describes the most common chimney repair problems and how to fix them.
