Concrete resurfacing in Victoria BC
Concrete resurfacing bonds a thin cement-based overlay onto concrete that is already in the ground. The old slab keeps doing the structural work, so the surface comes back in days instead of the weeks a tear-out needs. It works on a slab that is sound but stained, spalled or crazed. It does not work once the slab has moved.
What concrete resurfacing is, what it costs, and when a slab qualifies
Start with the money and the calendar, because that is what the decision usually turns on. Industry cost data puts a typical residential resurfacing project at $1,000 to $5,000, or $3 to $5 per square foot for a basic single-colour finish (HomeAdvisor, updated June 2026). The work runs in days rather than the weeks a tear-out and repour needs, because nothing is demolished and nothing is hauled away.
Resurfacing is a surface treatment, not a structural repair, and that distinction is the whole decision. The overlay is cement-based, goes on thin, and carries no load of its own. Everything underneath it still has to work.
So a slab qualifies on condition, not on age or appearance. If it has settled unevenly, heaved from a root, or crumbled right through its depth, an overlay will follow the problem instead of fixing it. If it is sound but tired, spalled from salt, stained, dusting, or crazed with hairline cracks, resurfacing gives you a new surface without the demolition, the disposal, or the three weeks of your driveway being a hole.
Finishes range from a plain broom or trowel texture through to stamped and stencilled overlays that read as flagstone, slate or brick. On this coast the practical constraint is slip resistance, because a smooth sealed patio in November is an ice rink with better drainage.
Will an overlay actually bond to your slab
That question has a real answer, and it is not a matter of opinion about products. A steel disc is glued to the surface, cored around to isolate a plug, and pulled straight up until something tears. The published standard method is ASTM C1583/C1583M-20, and its own scope describes the result as an indicator of the adequacy of surface preparation before a repair or overlay material goes on.
Two things follow from that, and both are worth knowing before anyone quotes you. First, when the test is run on a finished overlay it reports the bond to the substrate or the tensile strength of the overlay or the substrate, whichever is weaker. When an overlay lifts off a driveway, the back of it usually carries a thin wafer of old concrete. The slab surface tore. The adhesive did not fail, which is why buying a more expensive product does not rescue a badly prepared slab.
Second, the qualifying test you can run yourself is mechanical rather than visual. Sound concrete rings when you tap it. Delaminated concrete answers with a dull, hollow note, and that area has to come out rather than be covered. Oil and rubber contamination has to be ground off, because an overlay will not bond through it any more than a garage floor coating will.
Fix cracked concrete driveway without replacing
Yes, in most cases, and the sequence matters more than the product. Nothing goes over a crack until the crack has been dealt with.
We route each crack out to a clean, square edge, which removes the loose material at the sides and gives the filler something to grip. Structural filler goes in and gets ground flat. Spalled and pitted areas, usually where salt or freeze cycles have taken the surface off in flakes, get cut back and patched. Oil-stained sections get degreased and mechanically ground.
Then the slab gets profiled, primed and overlaid. The result is a single continuous surface rather than a patchwork, which is the part most people are after.
There is one exception. A crack that is still moving will come back through. Where we see displacement across a crack, a section sitting lower than its neighbour, or a crack that runs the full depth, we recommend a control joint, a partial replacement, or leaving it alone, rather than take money for an overlay that fails in two winters. The full self-assessment is in our guide to resurfacing versus replacing a driveway.
The slab moisture nobody quotes for on a coastal pour
The local search results will tell you about rain, frost and tyre marks. The more common reason a well-installed overlay lets go on this coast is water underneath the slab, not weather on top of it. Most Greater Victoria driveways, patios and garage floors were poured directly on grade, and the older ones have no vapour barrier beneath them at all. Ground moisture moves up through the concrete continuously, and once it meets a sealed surface it has nowhere left to go. It collects at the bond line and pushes the overlay off in patches, usually in the first wet season after the work.
This is measurable, and there are two published methods for measuring it. ASTM F1869 uses anhydrous calcium chloride and reports the result as the weight of water evaporating from 1,000 square feet of slab in 24 hours. ASTM F2170 instead drills in situ probes into the slab and reports the relative humidity inside it, which is the more useful reading for a slab that is about to be sealed.
A slab reading high on either test is not disqualified. It changes the specification: a moisture-tolerant primer, a breathable finish, or a mitigation coat, decided before material is ordered rather than after the first spring. The same reading decides whether a garage floor is ready for a coating, and it is the single test most residential quotes skip.
What concrete resurfacing costs, and what moves the number
No fixed price list appears on this site, and the reason is structural rather than coy: the condition of the slab, not its area alone, decides most of the number. But you should not have to start the conversation blind, so here is the published market range.
Industry cost data puts a typical residential resurfacing project at $1,000 to $5,000 (HomeAdvisor, updated June 2026). The same guide puts basic single-colour resurfacing at $3 to $5 per square foot, a decorative overlay at $6 to $10 per square foot, and stamped overlay work at $5 to $20 per square foot. A second industry source quotes a wider band of $4 to $25 per square foot across all overlay types (Sundek, 2026).
The two sources disagree at the top of the range because they are counting different work: the narrower guide splits stamped and decorative finishes into their own lines, the wider one folds every finish into a single band. Both sets are US figures, and currency, labour and freight on Vancouver Island move them, so read the shape of the range rather than the endpoints.
What actually moves your number: total area, how much routing and patching the slab needs before anything will bond, whether the surface has to be diamond ground rather than acid etched, the number of coats, whether a pattern or a second colour is involved, and whether the space has to be emptied first. A garage adds that last line every time.

How long does concrete resurfacing last
A properly prepared overlay on a sound slab typically gives ten to fifteen years on a residential driveway, and longer on a patio or walkway that never sees a vehicle. Interior and covered surfaces last longer again.
Three things move that number. Preparation is the first and largest, and the pull-off standard above is why: an overlay bonded to a clean, profiled slab and an overlay bonded to a dusty one are different products in practice, whatever the pail says. Drainage is the second, because water that sits on a surface, or under it, will find any weakness eventually. Victoria patios shaded by mature trees hold moisture for months and grow moss into anything with texture, which is worth planning for rather than discovering.
The third is sealing. Most decorative overlays want a penetrating or film-forming sealer refreshed every few years. We hand over what yours needs and when, in writing.
Resurfacing versus replacing
Replacement means breaking out the existing slab, hauling it away, re-preparing the base, forming, pouring and then waiting for it to cure before anything drives on it. It is the right answer when the base has failed, when drainage needs re-grading, or when the slab is structurally gone.
Resurfacing skips all of that. No demolition, no disposal, and a driveway back in service in days rather than weeks. It is substantially less expensive for the same reason: most of the cost of replacement is removal, disposal and base work, not concrete.
Condition decides this, not price. We walk the slab, look for movement, check the drainage and tell you which one your surface needs. Where that answer is replacement, we do not do that work, and we say so rather than sell you an overlay that fails.
So which surface does your property actually need
- Concrete, sound underneath, ugly on top. Resurfacing. Route the cracks, grind the contamination off, check the slab for moisture, then overlay.
- Concrete garage floor you want hard-wearing and cleanable. A resin system rather than a cement overlay. That is garage floor epoxy, and the moisture reading matters even more there.
- Asphalt, not concrete. A different job entirely. Driveway sealcoating protects the binder; no overlay is involved.
- A strata or commercial lot. Sealing and striping run on their own cycle. See commercial parking lot sealcoating.
- Displacement, hollow-sounding areas, or water running to the house. Neither. That is a base and drainage problem, and an overlay would lock it in.

Questions about this work
Other surfaces we treat
- Garage floor epoxyWe grind the slab back to clean concrete, test it for moisture, then build a flake or solid-colour coating that stops the dusting and shrugs off road salt.
- Driveway sealcoatingAsphalt on the coast loses its binder to rain and UV long before it loses its shape. We clean, fill and seal so the surface stays flexible instead of ravelling.
