Cracked Garage Floors
Cracks in garage slabs are common and usually cosmetic, but wide or active cracks can telegraph through a new coating if they are not treated correctly. Every slab is different, so recommendations depend on an on-site evaluation — we do not diagnose specific floors from photos alone.
Common causes
- Slab shrinkage cracks
- Control-joint separation
- Settlement or heaving in aggressive soil
How we approach it
- Static cracks repaired with compatible fillers
- Active joints treated with flexible sealant systems
- Coating installed only after repair
Preparation
- On-site evaluation of the concrete and any existing coating
- Moisture and adhesion testing where warranted
- Full mechanical preparation before any new material is installed
- Compatible repair materials for cracks, spalls, and pits
Frequently asked
Will cracks come back through the coating?
Static cracks can be repaired so they do not telegraph. Actively moving cracks require joint treatment — no coating stops slab movement.
