Professional Prep Makes the Difference
Professional Concrete Overlaysin St. George & Southern Utah
An overlay is only as good as its bond to the slab, and that bond is made in the prep. We assess the structure, grind and clean the surface, treat cracks, apply a bonding agent, then place and finish the overlay. Skip the prep and an overlay delaminates, no matter how good the material is.

Of bonded surface life
An overlay that fails almost always failed at the bond, and the bond is made before any new material goes down. Prep is the entire game.
Here is how a concrete overlay is actually done, and why the steps you cannot see decide whether it lasts.
“An overlay is all about the bond, and the bond is all about the prep. If we grind, treat the cracks, and prime it right, it behaves like part of the original slab. Skip that and it peels.”
Why prep decides everything
For an overlay to last, it has to bond as one with the existing slab. That means a structurally sound base, a mechanically profiled and spotlessly clean surface, properly treated cracks, and the right bonding agent. Miss any of those and the new layer separates from the old one.
It also means being honest about the slab underneath. An overlay is a surface system, so we confirm the base is sound before resurfacing it, rather than papering over a structural problem.
- Structural assessment of the existing slab
- Mechanical grinding to profile the surface
- Cracks routed, cleaned, and filled correctly
- Bonding agent for a true chemical bond
- Overlay placed and finished to uniform thickness
- Sealed for protection and performance
Placed and finished right
With the prep done, the overlay material is applied, screeded, and finished to a uniform thickness and the surface you want, then sealed. Consistent thickness and proper finishing are what give you a flat, durable result instead of a patchy one.
Done correctly, the overlay behaves like part of the original slab, which is exactly the goal.
Our step-by-step process
Structural Assessment
Determine if underlying concrete has structural issues that must be addressed before overlay
Surface Preparation
Mechanical grinding removes existing sealers, coatings, and creates the profile needed for bonding
Crack Treatment
Cracks routed, cleaned, and filled with flexible or rigid repair compound depending on crack type
Bonding Agent
Primer/bonding agent ensures the overlay chemically bonds to the existing concrete slab
Overlay Application
Material applied, screeded, and finished to uniform thickness, typically 1/4" to 1/2"
Finishing & Sealing
Surface finished to specification, sealed for protection and performance
Built for St. George & Washington County
Bonding and crack treatment matter even more in Southern Utah, because our temperature swings make a slab expand and contract daily. We use crack treatments and overlay systems that flex with that movement and bond strongly, so the surface does not separate or re-crack against the slab in our climate.
