Most vulnerable
- Poured concrete steps and slabs
- Lower-grade concrete pavers
- Anything already scaled
- Surfaces that stay wet
Winter salt damage on driveways and steps.
Salt is the second-biggest cause of surface damage in Ontario after base failure. It is also the one you have direct control over, which makes it worth two minutes of reading.

What it does
Salt accelerates the cycle, it doesn't dissolve the stone.
De-icers work by lowering the freezing point, which means the surface goes through more freeze-thaw cycles per winter rather than fewer. Each cycle stresses the top few millimetres, and over years that shows as scaling — the surface flaking away.
More tolerant
- Quality through-coloured pavers
- Natural stone
- Surfaces that drain and dry quickly
What actually helps
- Sand for grip instead of salt
- Less de-icer, applied deliberately
- Rinse in early spring
- Keep drainage working so it dries
Repair
What can be fixed, and what cannot.
Pavers
- Individual scaled units swapped out
- Re-sanding the joints
- Sealing to slow further damage
The advantage of a modular surface.
Concrete
- Resurfacing, rarely invisible
- Patching, visible
- Replacement where it is widespread
One slab means one repair option.
Steps
- Precast or natural stone replacement
- Often better than repairing badly scaled concrete
- Can be done without touching the driveway
Questions
Questions, answered.
Is salt bad for interlocking?
Harder on concrete than on quality pavers, but not harmless to either. Salt drives freeze-thaw cycling at the surface, which causes scaling — the surface flaking away. Cheaper units and poured concrete show it first.
What should I use instead?
Sand for grip, and only as much de-icer as you actually need. Where you do use it, rinsing the surface in early spring removes what is left before it sits through the wet season.
Does sealing protect against salt?
It helps at the surface, and it is a commitment — once sealed it needs redoing periodically. It does not protect a surface whose real problem is the base.
My concrete steps are flaking. Can that be repaired?
Resurfacing is possible and rarely invisible. Where the scaling is deep or widespread, replacing the steps — often in precast or natural stone — lasts longer and looks better than patching.
