Garage Slab Cracks: Cosmetic or Structural?
The garage is often where foundation movement shows first, because the slab is exposed. Here’s how to read garage cracks.
Common and minor
Shrinkage cracks and control-joint cracks in a garage slab are usually cosmetic and stable.
Worth a look
Cracks with vertical offset, a slab pulling from the foundation wall, or cracks paired with house signs point to movement and slab repair.
