Understanding what causes mortar to degrade can help you prevent future issues. Here are the top reasons mortar joints weaken over time:
1. Weather Exposure
Rain, snow, and fluctuating temperatures cause mortar to expand and contract, leading to cracks and erosion.
2. Moisture Intrusion
Constant exposure to moisture weakens the bond between mortar and brick, leading to spalling and cracking.
3. Improper Installation
Substandard mortar mixtures or poor application techniques can reduce the longevity of your masonry.
4. Age of the Mortar
Like any building material, mortar deteriorates over time, especially if your structure is several decades old.
5. Foundation Shifting
Shifting or settling foundations put additional stress on the masonry, causing cracks to form.
Regular maintenance and timely tuckpointing by professional masonry contractors near me in Winnetka can address these issues before they worsen.
