What's Wrong With Your Concrete? A Symptom-by-Symptom Guide
By Mike Romer, Owner · OKGN Concrete Sealing · Updated July 2026
Quick Answer
Most Okanagan concrete problems trace back to one thing: water inside the slab meeting 50–80+ freeze-thaw cycles a year. Match your symptom below — spalling, scaling, pitting, hairline cracks, dusting or efflorescence — and each guide gives you the cause and the honest verdict on what sealing can fix, what it can only prevent, and when you actually need a repair contractor instead of us.

Six Problems, Six Honest Answers
Click the one that looks like your concrete. Every guide covers what's actually happening, what causes it here in the Okanagan, and — honestly — whether sealing fixes it, prevents it, or whether you need a different trade first.
The Common Thread
Almost Every Problem Here Runs on Water
Spalling, scaling, pitting growth, crack widening, efflorescence — five of the six problems on this page are water problems wearing different masks. Water gets into the slab's pores, the Okanagan winter freezes it dozens of times, and each freeze expands it about 9% against the concrete around it.
That's why the honest fix is usually the same one: shut the water out. A penetrating sealer fills the pores and capillaries so there's nothing inside the slab to freeze — which is prevention for the damage that hasn't started and a stop-loss for the damage that has.
See the government climate data behind this in our city-by-city freeze-thaw breakdown — Kelowna alone logs about 69 freeze-thaw cycles and 150 frost days a year.
FAQ
Concrete Problems: Common Questions
How do I know what's wrong with my concrete?
Match the symptom: chunks breaking off exposing stones = spalling; the thin top skin peeling in flakes = scaling; small holes peppering the surface = pitting; fine lines = hairline cracks; constant grey powder = dusting; white chalky residue = efflorescence. Each has a different cause and a different honest answer on whether sealing helps — the guides here walk through all six, and a free on-site assessment settles it definitively.
Can concrete sealing fix damaged concrete?
It depends on the damage — and an honest contractor tells you which is which. Sealing genuinely fixes dusting (it chemically hardens the weak surface) and stops the water intrusion behind spalling, scaling, pitting, hairline-crack widening and efflorescence. What it can't do is rebuild material that's already broken away or fill cracks — deep spalling, widespread scaling and wide/offset cracks need a repair or resurfacing contractor first, then sealing protects the result.
Why does concrete fail so fast in the Okanagan?
Freeze-thaw frequency. The Okanagan spends winter hovering around 0°C — Kelowna sees roughly 69 freeze-thaw cycles and 150 frost days a year — and every crossing lets water inside the slab freeze, expand about 9%, and pry the surface apart. Add intense summer UV and winter road salt, and unsealed concrete here deteriorates faster than in most of BC. That's also why sealing pays off more here than almost anywhere.
When is concrete too far gone to seal?
When the surface you'd be sealing is already gone: deep spalling across large areas, scaling over most of the slab, heavy pitting you want smoothed, or cracks that are wide, offset or growing. Those need a repair or resurfacing contractor first — sealing then protects the new surface. If the slab is sound and the damage is early or localized, sealing is the right move and the cheaper one. We'll tell you which side of the line you're on, free.
