What is the significance of a hairline crack in a brick veneer wall?
A. If there is a crack in a brick veneer wall or any brick wall for that matter, then some settlement has occurred near this location. If there is no visible opening at the top, most of the time this can be monitored for movement as long as vertical sheer or displacement has not occurred. If the cracks continues to open as time passes, it is recommended that an engineer further review this area to determine what corrective action may be needed.
