- The crack will be small and vertical, usually less than 1/8” wide.
- The crack is in the foundation wall only and does not extend up through the structure.
- Shrinkage cracks usually occur in the middle third of the length of the foundation wall. If it’s located toward the end of the length of the foundation wall, it is probably not a shrinkage crack.
- Crack size: Settlement cracks more than 1/4” wide are more likely to indicate ongoing movement than smaller cracks.
- The direction of movement: The edges of a typical settlement crack line up and fit together vertically, much like pieces of a puzzle. If the edges of the crack have shifted, or sheared so that they no longer line up, the 1/4” rule described above doesn’t apply. This type of crack can be a significant structural concern.
- Repaired and re-cracked: Unless it is a hairline crack, a settlement crack that was repaired and has re-cracked could also indicate ongoing movement and should be addressed.
