Key takeaways
- Hairline cracks are usually easy to repair
- Moving cracks need flexible fillers
- Repairs are ground flush before coating
- Active settlement needs a different fix
Understand the crack
Cracks come from shrinkage, temperature, loads and soil movement. Hairline cracks that have not grown are usually cosmetic. Wider cracks or ones that are growing, offset or leaking water need a closer look.
Measure width and check for height differences across the crack.
The repair
Rigid fillers like epoxy suit stable cracks. Flexible sealants suit joints and cracks that move. The crack is cleaned, filled and ground flush.
Even a good repair can sometimes reflect through a thin coating, and we explain that up front.
When coating is not the answer
If a slab has settled, heaved or crumbled, coating will not solve it. A structural repair or replacement may be better.
We tell you honestly when a slab is a poor candidate.

Quick answers
Will the crack come back through?
It can, especially if the slab moves. Flexible fillers and thicker systems reduce the chance.
Can you hide cracks completely?
Many cracks disappear under flake or overlay, but we do not promise an invisible repair.
