Water Infiltration: Challenges and Solutions for Masonry Buildings
Masonry buildings are celebrated for their strength, character, and longevity, but they are not immune to water infiltration. If left unaddressed, moisture can compromise both structural integrity and appearance. Recognizing the signs, understanding common sources, and taking proactive steps are key to preserving your investment.
Signs of Water Infiltration
Early detection can save building owners from costly repairs. Common signs include damp or discolored walls, efflorescence (white, powdery deposits), musty odors, peeling paint, and visible mold or mildew. On the exterior, watch for cracking mortar joints, spalling (flaking or crumbling bricks or stone), and stained or bulging walls. Immediate attention is essential if any of these symptoms appear.
Sources of Water Infiltration
Moisture often enters masonry through deteriorated mortar joints, damaged or missing flashing, porous masonry surfaces, and poorly maintained gutters and downspouts. Ground-level issues, such as improper site drainage, can also cause persistent foundation moisture problems.
Treatment Strategies
To effectively combat water infiltration, a combination of proven repair and prevention techniques is essential. Here are the key strategies used to restore and protect masonry buildings.
- Tuckpointing: Cracked or eroded mortar joints allow water infiltration. Tuckpointing involves carefully removing deteriorated mortar and replacing it with new in the appropriate strength, color, and finish. This restores structural integrity, enhances moisture resistance, and extends the life of the masonry
- Flashing: Flashing directs water away from vulnerable areas like windowsills, roofs, and foundations. Through-wall flashing, installed with a drip edge and weep holes for drainage, is especially effective at preventing hidden moisture damage
- Sealants: Breathable sealants form a water-resistant barrier while allowing internal moisture to escape. When selected for high permeability and properly applied, they protect against rain absorption, freeze-thaw damage, and efflorescence
