If you’ve spotted flaking concrete, bubbling paint, or strange rust-coloured stains on your exterior walls or driveway, you might have spalling. And while it doesn’t sound as dramatic as “foundation failure,” trust us, it’s not something you want to ignore.
What exactly is spalling?
Spalling is when the surface of concrete or brick starts to break away, peel, flake, or crack. It often shows up on:
- Boundary walls
- Foundations
- Driveways
- Balconies or patios
- Concrete stairs or retaining walls
At first, it may look like just some cosmetic chipping, but underneath the surface, there’s usually a bigger issue: moisture. Water seeps in and causes the steel inside to rust, expand, and push the surface outwards — causing the cracking you see.
What causes it?
- Poor original construction
- Coastal air with high salt content
- Water leaks and poor drainage
- No waterproofing or sealant protection
- Natural wear and tear over time
If left untreated, spalling can:
- Spread and worsen
- Weaken the structural integrity of your home
- Lead to higher repair costs
- Create safety hazards — especially on stairs or balconies
