Construction writer & concrete industry enthusiast based in Toronto. Covering concrete repair, crack & spall remediation in Toronto and the GTA concrete trade.
Cracked. Spalled.
Uneven. Fixed.
Cracked Concrete
Hairline to structural cracks — routed, cleaned, and filled with polyurethane or epoxy injection. Control joint re-cutting where needed.
Spalling Concrete
Surface scaling and delamination repaired with bonded overlays or partial-depth patch using high-strength concrete repair mortar.
Uneven Concrete
Slab lifting with polyurethane foam injection (mudjacking alternative) or full panel replacement for severely settled sections.
Steps & Edges
Broken step noses, crumbling edges, and damaged risers rebuilt with formed concrete repair — matched finish where possible.
Sidewalks & Walkways
City standard compliance repairs, trip-hazard elimination, panel replacement. We handle permit requirements for boulevard work.

Honest advice,
not upselling.
Repair is right when
- ✓Cracks are isolated and under 3 mm wide
- ✓Spalling affects less than 20–25% of the surface
- ✓The sub-base is still solid with no voids
- ✓Slab is less than 20 years old
- ✓Heaving is from a removable cause (tree root, drainage fix)
Replace instead when
- ✓Cracks run through multiple panels or are structural
- ✓Spalling or scaling covers more than 30% of surface area
- ✓Slab has settled due to a failed sub-base
- ✓There is corrosion or ASR (alkali-silica reaction)
- ✓Cost of repair exceeds 50–60% of replacement cost
Common questions.
Should I repair or replace cracked concrete?
Repair works when cracks are isolated, spalling covers under 20–25% of the surface, and the sub-base is solid. Replace when damage is structural, spans multiple panels, or repair cost exceeds 50–60% of a new pour.
How much does concrete repair cost in Toronto?
Small crack injection and patching starts in the low hundreds; larger spall repairs or slab lifting run higher. We give a firm price after seeing photos or visiting the site.
Why is my concrete spalling or scaling?
Spalling is usually caused by freeze-thaw cycles combined with deicing salt, poor air-entrainment in the original mix, or surface finishing done too early. We match the repair method to the cause.
Can you fix an uneven or sunken slab without replacing it?
Often yes — polyurethane foam injection lifts and levels settled slabs (a mudjacking alternative) without the cost or mess of full replacement, as long as the concrete itself is still sound.
How long does a concrete repair take?
Most crack injections and patches are same-day. Slab lifting typically takes a few hours. Full panel replacement needs cure time before traffic, usually 7 days.
Do you repair sidewalks that the city has flagged?
Yes, including trip-hazard grinding, panel replacement, and permit handling for boulevard work to bring sidewalks into municipal compliance.
