Key takeaways
- Overlays suit structurally sound slabs.
- Active settlement and heave call for replacement.
- Cracks can reflect through; repair first.
- A site visit is the only reliable way to decide.
When an overlay is the better value
If the slab is solid, level and mostly intact, a bonded stamped overlay gives a brand-new look at a fraction of the cost and mess of replacement.
When replacement is smarter
Slabs that are heaving, sinking, badly cracked or poorly built will not hold an overlay. In that case, tearing out and starting with a proper base is the honest recommendation.
What we check
We look for movement, delamination, spalling, drainage and thickness. We sound the slab, test bond and review the history of the pour.
Setting expectations
An overlay can reflect hairline cracks and will follow the slope of the slab below. It will not fix drainage or structural problems.
Cost and timing
Overlays are faster and usually cheaper. Replacement costs more but resets the foundation, which can be worth it for failing slabs.
