Soil movement, coastal moisture, and heat expansion cause concrete to crack in Orange County. In addition, slabs naturally shift over time. Homeowners frequently ask: Can concrete resurfacing fix cracked concrete, or does it need replacement?
The answer depends on the type and severity of the cracks.
Hairline Cracks vs Structural Cracks
Consider cracks on a case-by-case basis, as not all cracks are the same.
Hairline cracks often result from normal shrinkage during curing. These cosmetic surface-level fractures make ideal candidates for concrete resurfacing.
Structural cracks must be considered differently. Widening cracks and cracks that create an uneven surface or are caused by foundation movement may require foundation repair first. Resurfacing alone may only be a temporary fix.
At Crank Waterproofing Decking and Roofing, every project begins with an evaluation to determine the suitability for resurfacing.

When Concrete Resurfacing Works
Concrete resurfacing works best when:
- Cracks are narrow and non-moving
- The slab remains structurally sound
- There is no significant vertical displacement
- The surface damage is primarily cosmetic
Professional resurfacing involves routing and repairing cracks, applying bonding agents, and installing a cement-based overlay that creates a new, uniform surface.
When done correctly, concrete resurfacing restores appearance and improves durability without the cost of replacement.
When Replacement Is Necessary
Resurfacing is not a cure-all. Replacement may be required if:
- The slab is sinking or heaving
- Large sections are separated
- Moisture is infiltrating from below
- Rebar corrosion causes deep spalling
In these situations, resurfacing over unstable concrete only masks the problem.
An experienced concrete contractor like Crank Waterproofing Decking and Roofing provides an honest, professional evaluation and opinion on whether resurfacing is appropriate.
The Role of Waterproofing on Decks
For balconies and elevated decks, cracks allow water intrusion into framing below. Here, concrete resurfacing must be paired with waterproof membrane systems.
This is especially important in Orange County, where coastal air accelerates moisture-related deterioration.
A Cost-Effective Solution for the Right Situation
When cracks are cosmetic and the slab is stable, concrete resurfacing offers a significantly more affordable option to tearing out and replacing concrete. It also minimizes disruption and construction time.
The key is accurate diagnosis.
