7 Signs You May Need Driveway Replacement in Fort Lauderdale FL
Not every crack means replacement. Concrete cracks — that's normal and often cosmetic. What matters is the pattern, the width, whether the sides have moved relative to each other, and what the water is doing. Here are the seven signs we look for on Fort Lauderdale properties.
1. Cracks that have width and vertical offset
A hairline crack is fine. A crack wide enough to catch a coin, especially where one side sits higher than the other, means the slab has moved and the support underneath has changed. Offset cracking is structural, not cosmetic, and filler will reopen within a season.
2. Sections that have settled or rock underfoot
If a section is lower than its neighbors, or moves slightly when a car drives over it, there's a void beneath the slab. On sandy Broward soils this usually means water has washed out base material. You can fill the crack, but you can't fill the void from above.
3. Surface spalling and flaking
Spalling is when the top layer flakes off and exposes aggregate. Small isolated spots can be repaired or resurfaced. Widespread spalling across the whole driveway usually points to finishing or curing problems at the original pour, or to reinforcement corroding below the surface — neither of which resurfacing fixes for long.
4. Water pooling or running the wrong way
Water standing on the driveway after a storm, or worse, flowing toward the garage or the house, means the slope is wrong. Grinding a surface doesn't create slope. Fixing it properly means removing the slab, correcting the grade, and repouring with the right pitch toward the swale or street.
5. A history of patches that keep failing
If your driveway is a map of previous repairs and the new cracks appear beside the old patches, the underlying problem was never the surface. At some point patch spending exceeds replacement cost and you still have a driveway that looks patched.
6. The slab is too thin for what parks on it
Look at a broken edge and you can often see the thickness. A three-inch slab under a work truck or boat trailer will keep cracking no matter how many times it's repaired. If your vehicles have changed since the driveway was poured, replacement at five or six inches solves a problem repairs can't.
7. Tree root lifting and edge failure
Mature root systems lift slabs from below and crack them along irregular lines. Replacement is the opportunity to address roots, adjust the layout, and rebuild the base so the new slab isn't fighting the same battle.
When repair is genuinely the better call
- Damage is confined to one defined section or the apron
- The rest of the slab is flat, well drained, and adequately thick
- Cracks are hairline with no vertical movement
- Surface wear is cosmetic and the structure is sound
What replacement actually involves
Demolition and haul-away, regrading and compacting the subgrade, a fresh compacted crushed stone base, reinforcement set at the right height, a correctly thick pour, control joints cut at planned spacing, and slope away from the garage. Most residential driveways are poured in a single day, with roughly a week before vehicles return.
