How do cracks develop in my indoor brick wall?
You must immediately treat all cracks and other defects in an indoor brick wall, no matter how big they are. The brick wall likely bears a portion of weight from the structure above it. You'll need to know what's causing these cracks if you are to avoid further deterioration of the wall.
Possible Causes of Brick Wall Cracks
Stress is often the key basis for brick wall cracks. This stress can result from a variety of structural problems, like having too few expansion joints in your structure. Stress and cracking can result from masonry ties that are failing or even from your building's foundation settling over time.
