Rain, leaks, and runoff pose a significant threat, as they can lead to cracking, crumbling, and structural damages extending beyond the masonry work itself.
What Is the Most Common Cause of Damage to Masonry?
Excessive moisture is particularly damaging during the freezing and thawing cycle. When water infiltrates the bricks and freezes, it expands and creates pressure on the masonry. As the freeze-thaw process repeats over time, it weakens the integrity of the bricks, resulting in spalling and crumbling. This is especially problematic in areas with harsh winters.
Another common cause of masonry damage is poor drainage. If water isn’t able to properly drain away from the foundation or walls, it can accumulate and saturate the masonry. The excess moisture can lead to efflorescence, a white powdery substance that forms on the surface of bricks. Not only is efflorescence unsightly, but it’s also an indication of moisture damage and can cause further deterioration if left untreated.
If the mortar joints aren’t properly laid, the bricks may not have sufficient stability and can shift or crack. Additionally, shortcuts taken during the construction process, such as using low-quality materials or inadequate reinforcement, can compromise the strength and longevity of the masonry.
Natural disasters like earthquakes and storms can also cause significant damage to masonry structures. The force and movement generated during these events can lead to cracks, fractures, and even collapse. It’s crucial to ensure that masonry buildings are constructed to withstand such forces and to have regular inspections and maintenance to detect any potential damage early on.
Taking preventive measures, such as sealing and waterproofing, can also help minimize the risk of moisture damage and prolong the lifespan of the masonry.
