Spalling refers to the breakdown of bricks. When bricks crack, crumble, peel, or chip, this is called spalling.
What Damage Can Spalling Bricks Cause?
Spalling bricks can be a major problem. If not repaired or replaced, the bricks can fall out. This interferes with the structural integrity as well. Spalling bricks are more common in historical or older properties. Over time the integrity of the bricks can break down causing this spalling.
What Causes Spalling Bricks?
