Cracks, in order of worry
| Crack | What it usually is | Usual answer |
|---|---|---|
| Hairline, straight in a joint | Shrinkage, as intended | Seal if it collects water |
| Hairline, wandering across a panel | Shrinkage between joints | Often just watch; seal |
| Wide and open | Movement or lost support | Repair and find the cause |
| One side higher than the other | Settlement | Leveling or replacing the panel |
| Many cracks through one panel | The panel is breaking up | Cut out and replace |
Control joints are cut so that shrinkage cracks happen in the joints; hairline cracks elsewhere are common and are not by themselves a failure.
What the numbers show
- Saw cut Cut from the top soon after the surface can take a saw.
- Cut depth About a quarter of the slab's depth; the uncut rest below is what cracks.
- Crack at the joint A hairline crack that follows the cut, as intended.
- Slab Held together by the uncut depth and by aggregate interlock across the crack.
- Base Supports the slab on both sides of the crack.
What a repair can do
Crack sealing keeps water and dirt out of a crack. A resurfacing overlay is a thin new layer that sticks to a sound old slab; it renews a worn or flaking surface but hides rather than fixes cracks that come from movement. Cutting out and replacing a section fixes a panel that is broken up. None of these makes a slab crack-proof.
What the numbers show
- Hairline in a joint Shrinkage, as intended; seal it if it collects water.
- Wandering hairline Shrinkage between joints; often just watched.
- Wide offset crack Movement or lost support; repaired and the cause found.
- Broken-up panel Many cracks through one panel; usually cut out and replaced.
When resurfacing fails
An overlay peels or cracks through when the old slab is moving, when the surface was not cleaned and prepared, or when water gets under the edges. If cracks are wide, uneven or still growing, the cause is dealt with first.
What repair typically costs in Rialto
For 240 square feet, half a driveway:
| Repair | Per sq ft | 240 sq ft |
|---|---|---|
| Crack repair and sealing, hairline | $2–$6 | $480–$1,440 |
| Resurfacing overlay | $3–$7 | $720–$1,680 |
| Slab leveling, foam or mudjacking | $4–$12 | $960–$2,880 |
| Cut out and replace sections | $9–$16 | $2,160–$3,840 |
Wide cracks, flaking and sunken slabs add per square foot; sealer after the repair, joint re-caulking and haul-away are options. Market estimates, not quotes.
Concrete Repair and Resurfacing — common questions
Is it normal for new concrete to crack?
Hairline cracks are common, especially in the joints. Wide, uneven or growing cracks are not, and are looked at.
Can a cracked driveway just be resurfaced?
If the old slab is sound and the cracks are hairline, often yes. If the slab is moving or broken up, an overlay hides the problem for a while and then fails.
