Toe-crushing is a localized failure mode in masonry walls, typically occurring at the base or the lower corners (the toe) of the structure. It happens when compressive forces, often combined with lateral loads like wind or earth pressure, exceed the crushing strength of the bricks or mortar. The material at the compression edge physically breaks apart, compromising the stability of the entire wall.
Heard on the job
The retaining wall is showing severe toe-crushing near the footing, meaning we've to shore it up immediately.
