Concrete is durable, dependable, and made to last — but like anything exposed to weather, heavy use, and time, it eventually shows signs of wear. The good news is that many concrete problems can be fixed if they’re addressed early. But left alone, minor issues can grow into costly repairs or full replacements.

At Vicente Outdoor Living, we help homeowners determine whether their concrete can be repaired, resurfaced, or if it’s time for a complete replacement. If you’re unsure about your driveway, patio, walkway, or slab, these are the top signs to look for.

1. Cracks That Keep Expanding Over Time

Small hairline cracks are normal as concrete naturally expands and contracts. The issue is when cracks grow wider, longer, or begin to spread in multiple directions.

Cracks become a concern when:

  • they exceed 1/8 inch
  • pieces start separating
  • water enters and freezes
  • they appear suddenly
  • several cracks form in the same area

Expanding cracks almost always need professional repair — or replacement if the foundation is compromised.

2. Sinking or Uneven Concrete Sections

If a section of your concrete drops lower than the surrounding area, you may be dealing with soil erosion or poor base preparation.

Common causes include:

  • water pooling
  • erosion under the slab
  • soil that wasn’t compacted correctly
  • tree roots affecting the ground

Uneven concrete is not just a cosmetic issue — it’s a safety hazard.

3. Pooling Water on the Surface

Concrete should always direct water away from your home. Standing water suggests a problem.

Water pooling indicates:

  • improper drainage
  • low spots forming
  • sinking slabs
  • uneven surfaces

Water damage accelerates cracking, erosion, and structural failure.

4. Surface Flaking or “Spalling”

If the top layer of your concrete is chipping, flaking, or peeling away, this is called spalling.

Spalling happens when:

  • moisture penetrates the concrete
  • freeze-thaw cycles occur
  • the surface wasn’t finished properly
  • de-icing chemicals were used

Spalling spreads quickly once it starts — resurfacing or replacement is usually required.

5. Stains or Discoloration You Can’t Remove

Concrete can stain over time, especially from oil, rust, or plant material. Occasional discoloration is normal, but deep, permanent stains can indicate deeper issues.

Stains may signal:

  • bacteria growth
  • moisture intrusion
  • chemical damage
  • top-layer deterioration

If the integrity of the concrete is affected, it may need more than a cleaning.

6. Crumbling or Deteriorating Edges

The edges of patios, driveways, and walkways experience the most stress.

Deteriorating edges show:

  • frequent chipping
  • broken corners
  • weakened structure
  • poor original installation

Strong edges are essential for long-term durability.

7. Visible Gaps Between Joints

Concrete is installed with control joints to prevent random cracking. If those joints begin to separate or widen, it’s usually a sign of structural movement.

Gaps occur due to:

  • shrinking soil
  • ground shifting
  • improper joint spacing
  • extreme weather changes

Narrow gaps can be filled, but larger ones require deeper repair.

8. Concrete Lifting Due to Tree Roots

Tree roots growing under concrete can cause sections to lift unevenly.

This often affects:

  • sidewalks
  • driveways
  • front walkways
  • patios near landscaping

If lifting continues, the concrete must be repaired or replaced — possibly with root barriers installed.

9. Rough, Pitted Surfaces (Surface Wear)

Over time, concrete may become rough, pitted, or eroded.

This shows up as:

  • tiny holes
  • sand-like texture
  • uneven wear
  • surface weakening

This type of decay usually requires resurfacing or a new pour.

10. Major Cracks Along Driveway or Patio Joints

If you see large cracks at structural seams, this may be a sign the slab has shifted or sunk.

These types of cracks indicate:

  • soil instability
  • major settling
  • incorrect base preparation
  • water issues

This typically requires replacement or section repair.

11. Moss, Mold, or Algae Growth

Consistent moisture causes organic growth that can weaken concrete.

This may indicate:

  • poor drainage
  • excessive shade
  • standing water
  • moisture penetrating the slab

Cleaning helps, but long-term moisture issues must be addressed.

12. Your Concrete Is 25–30+ Years Old

Even well-maintained concrete eventually weakens.

Older concrete may develop:

  • structural cracks
  • settlement issues
  • major wear
  • deep surface damage

Age alone isn’t always a reason to replace — but it often contributes to other problems.

Repair vs. Replacement — Which Do You Need?

Repair is possible when:

  • cracks are shallow
  • slab is mostly level
  • damage is surface-level
  • moisture hasn’t penetrated deeply

Replacement is needed when:

  • slab is sinking
  • major cracks spread across the surface
  • rebar or structure is compromised
  • drainage issues are severe
  • multiple repairs would cost more than replacement

A professional assessment helps determine the safest, most cost-effective solution.

Why Address Concrete Damage Early?

Fixing issues early prevents:

  • bigger cracks
  • trip hazards
  • structural failure
  • expensive repairs
  • water damage
  • foundation problems

Well-maintained concrete protects your home and keeps your outdoor space looking clean and beautiful.
