Concrete grinding · Toronto and the GTA · Since 2015
Concrete Grinding Toronto
Trip hazards ground flush. Floors ground flat and ready to coat.
Toronto Concrete Repairs grinds lifted sidewalk and walkway slabs, levels uneven floors, removes old paint, epoxy and adhesive, and prepares concrete for coatings, overlays and polishing, for homes and commercial properties across the GTA. Dust controlled, and usually done in one visit.
Quick answer
What is concrete grinding, and when is it the right fix?
Concrete grinding uses diamond tooling to remove a thin layer of the concrete surface. It's used to grind down trip hazards where one slab has lifted above the next, to level uneven floors, to remove old paint, epoxy, sealers and adhesive, and to prepare concrete so a new coating, overlay or polish bonds properly. Ontario's minimum maintenance standard for municipal sidewalks treats a step of more than 2 cm, about three quarters of an inch, as a hazard, and property owners and managers use the same yardstick. Grinding fixes it in place, without breaking out the slab, at a fraction of the cost of replacement. When a slab has lifted too far or is broken, Toronto Concrete Repairs will tell you, and price the repair or replacement instead.
What we grind
Concrete grinding services in Toronto
Six jobs grinding does well, and where each one leads next.
Trip hazards and lifted slabs
Sidewalks, walkways, plaza entrances and driveways where one slab sits above the next. Ground to a smooth taper so nobody catches a toe.
Floor prep for epoxy and coatings
Diamond ground to the profile coating manufacturers require, so the coating bonds instead of peeling. The step most cheap epoxy jobs skip.

Coating, paint and adhesive removal
Peeling epoxy, floor paint, old sealers, carpet and tile adhesive ground off back to clean, sound concrete.
Prep for overlays and resurfacing
Porches, steps, walkways and pool decks ground before a new surface goes on, so the overlay or Graniflex bonds to sound concrete.
Warehouse and commercial floors
Lips at joints, high spots, worn aisles and old line paint ground flat for forklifts, racking and new coatings.
Grinding for polished concrete
The first passes of every polished floor: coarse grinding to open and flatten the slab before densifier and the finer polishing passes.

Grind it, or replace it?
Grinding is the cheapest fix for an uneven slab, but only when the slab is sound and has stopped moving. Here's how we tell.
Grinding is the right fix
Grinding won't fix it
When grinding isn't enough, the section is repaired or replaced, or for commercial sites, replaced in stages so the site stays open. A photo with a tape measure or a coin against the lip tells us which.
Property managers and commercial owners
Trip hazards fixed before they turn into claims
A lifted slab at a plaza entrance or a condo walkway is a liability every day it's there. Send a photo and the address and we'll quote it the same day, grind it in one visit where possible, and send before and after photos for your file. See how we work with property managers and on commercial sites.
The process
How we grind concrete
Simple job, easy to do badly. These five steps are the difference between a clean, flush finish and a gouged slab and a dusty house.
Assess
Lift measured, slab checked for cracks and movement, and the finish agreed: flush taper, coating prep, or polish.
Protect
Doors, walls, landscaping and drains covered. Indoors, the area is sealed off from the rest of the building.
Grind
Diamond tooling on shrouded grinders connected to industrial vacuums, so the dust goes in the bag, not the air.
Taper and check
Trip edges feathered to a gentle slope, floors checked with a straightedge, and edges hand ground where machines can't reach.
Clean and finish
Vacuumed and cleaned, then sealed, coated or handed over ready for the next trade. Photos sent for your records.

Questions
Concrete grinding: common questions
Usually, yes. If the slab is whole and has stopped moving, the raised edge is ground to a smooth taper so the step disappears. It's much faster and cheaper than breaking out and repouring, and the walkway stays in use. If the lift is too large, the slab is broken, or it's still rising, grinding is the wrong fix and we'll tell you so and price the repair or replacement instead.
Ontario's minimum maintenance standard for municipal sidewalks treats a vertical step of more than 2 cm, about three quarters of an inch, as a hazard that has to be repaired. Many property managers and insurers use the same yardstick on private walkways. Smaller lips still catch toes and are worth grinding, especially at entrances.
It depends on what's being ground: a single trip hazard, a whole floor prepared for coating, or an old coating removed. Area, access and how much material has to come off set the price. Text a photo with a tape measure or coin against the lip, or a photo and rough size of the floor, and you'll have a written quote, the same day for trip hazards.
Uncontrolled grinding is. We use shrouded grinders connected to industrial vacuums, so the dust is captured at the disc. Indoors, the work area is also sealed off from the rest of the house or building. There's some fine dust to vacuum at the end, not a cloud through the house.
Grinding gives a consistent surface profile across the whole floor and removes old sealers, oil and laitance that acid can't. Coating manufacturers specify a mechanical profile for their warranty, and it's the main reason our epoxy floors don't peel. Acid etching is cheaper and is a common reason other floors fail.
Yes. Peeling epoxy, floor paint, sealers, and carpet or tile adhesive are ground off back to clean concrete, ready for a new coating, an overlay, a polish or flooring. Some thick or rubbery materials need a scraping pass first; we'll tell you from photos.
Most trip hazards take well under an hour each, so a whole walkway or several sites can be done in one visit. Floor prep for a coating usually runs one day for a garage or basement; larger commercial floors are scheduled to fit around operations, including evenings and weekends.
When grinding is the preparation for a coating or overlay, the finished system carries our written warranty: ten years on coatings depending on the surface, and three years on overlays and new concrete. The terms are in your quote before you sign.
