Crack repair is where our repair-first philosophy actually gets tested. Almost every crack we look at has a cheaper answer than replacement, but only if it is diagnosed correctly first. The four methods available do completely different jobs, and using the wrong one is the reason so many homeowners have had the same crack “repaired” twice. **Epoxy injection** is structural. A low-viscosity resin such as Sikadur is injected through surface-mounted ports into a dry crack, filling it to full depth and bonding the two faces back into one piece of concrete. Properly done, the repaired crack is stronger than the surrounding concrete. **Hydrophobic polyurethane injection** is for water. It reacts with moisture, expands into the crack and seals it. Epoxy cannot cure properly in a wet crack, so an actively leaking foundation wall gets polyurethane, not epoxy, regardless of whether the crack is also structural. **Carbon-fibre stitching** is for movement. Strips of high-tensile fabric are bonded perpendicular across the crack so the two sides can no longer separate. If a crack is still active, this step is not optional: fill it without stitching and it cracks again along the same line. **Cosmetic sealing** is for stable hairline cracks. Routing and filling them with a flexible or semi-rigid sealant keeps water and chloride out, which is what stops a hairline crack becoming a structural one over five winters. ### What’s Included - Crack diagnosis: structural or shrinkage, active or static, wet or dry - Crack cleaning, routing and surface preparation - Surface seal and injection port installation - Low-viscosity epoxy or hydrophobic polyurethane injection to refusal - Carbon-fibre stitching where movement is present - Port removal, grinding flush and surface patching - Colour-matched finish on visible surfaces - Advice on monitoring and preventing recurrence ## Common Problems We Solve ### Cracks Growing Wider Each Winter Water gets into a hairline crack, freezes, expands, and widens it a fraction of a millimetre. Repeat that a hundred times a winter for a decade and a hairline becomes a structural problem. Sealing early is the cheapest intervention in concrete repair, and keeping the whole slab under a penetrating sealer [/concrete-sealing-waterproofing/ →](/concrete-sealing-waterproofing/) is what stops the next crack starting. ### Rust Staining Along a Crack Line That means chloride from road salt has reached embedded rebar and it is corroding. Corroding steel expands to several times its original volume and splits the concrete from inside. The crack is a symptom, and the repair has to address the rebar as well as the concrete. ### Leaking Foundation Cracks Water appearing on a basement wall after heavy rain almost always traces to a specific crack. Polyurethane injection seals it from inside. Where the underlying cause is exterior water pressure or a blocked weeping tile, we say so, because sealing from inside alone treats a symptom, and that work belongs under concrete foundation repair [/concrete-foundation-repair/ →](/concrete-foundation-repair/) rather than a single injection. ### Cracks That Keep Coming Back Almost always a moving crack that was filled but never stitched. Carbon fibre stops the movement. Without it, the best filler in the world simply becomes a new crack in the same place. ## How Much Does Crack Repair Cost in Toronto? Repairs are priced per crack at $200 to $600. Drivers: - **Method.** Cosmetic sealing is cheapest, structural stitching most involved. - **Length and width.** Long cracks need more ports and more material. - **Access.** A crack in an open driveway is easier to work on than one behind finished basement framing. - **Wet or dry.** Active leaks need polyurethane and often need staged injection. - **Quantity.** Several cracks on one visit are considerably cheaper per crack than separate call-outs. ## Repair or Replace? This is the question that saves Toronto homeowners the most money, and the answer is repair more often than the industry admits. About half the slabs we are called out to replace can be repaired at roughly 40 percent of the cost. Repair when cracks are isolated, when the slab is otherwise sound, when there is no widespread surface scaling, and when the base has not failed. Where the concrete itself is fine but the slab has settled, concrete lifting and levelling [/concrete-lifting-levelling/ →](/concrete-lifting-levelling/) is usually the cheaper fix, and a worn but structurally sound surface can be renewed with concrete resurfacing [/concrete-overlays-resurfacing/ →](/concrete-overlays-resurfacing/) . Replace when cracking runs through multiple panels with vertical displacement, when the slab rocks under load, when the surface has scaled across most of its area, or when the sub-base has washed out and lifting would only be temporary, which usually means a new concrete driveway [/concrete-driveways/ →](/concrete-driveways/) . We assess it on site and tell you plainly. If replacement really is the right call, we will say that too, because a repair that fails in a year costs everybody more than an honest answer on day one.

Bramalea Common questions ## Crack Repair FAQs ### help How much does concrete crack repair cost in Toronto? expand\_more Crack repair is priced per crack at $200 to $600. Cosmetic sealing sits at the lower end, structural epoxy injection in the middle, and carbon-fibre stitching at the top. Repairing several cracks on one visit is cheaper per crack than separate call-outs. ### help What is the difference between epoxy and polyurethane injection? expand\_more Epoxy is rigid and structural. It bonds the two faces of a crack back together so the concrete is monolithic again, and it is the right choice for a dry structural crack. Hydrophobic polyurethane is flexible and expands on contact with water, so it is the right choice for an actively leaking crack where epoxy cannot cure properly. ### help What is carbon-fibre stitching? expand\_more Strips of high-tensile carbon-fibre fabric epoxied perpendicular across a crack so the two sides can no longer move apart. It is used when a crack is still active. Filling a moving crack without stitching it means the filler simply cracks again along the same line. ### help How do I know if a crack is structural? expand\_more Width, displacement and behaviour. A hairline crack with no vertical offset that has not changed in years is usually shrinkage. A crack wider than a pencil, or one where one side sits higher than the other, or one that is visibly growing, is structural. We assess it and tell you which you have. ### help Can crack repair stop a leaking basement wall? expand\_more Yes, in most cases. Hydrophobic polyurethane injected into an active crack expands and seals the full depth of the wall. Where the cause is exterior water pressure and poor drainage, we also look at the outside, because sealing from inside alone treats the symptom. ### help Why does concrete crack in Toronto? expand\_more Four main causes. Shrinkage as new concrete cures, which is normal and controlled by joints. Freeze-thaw cycling widening existing micro-cracks. Settlement when clay subgrade moves. And chloride from road salt corroding embedded rebar, which expands and splits the concrete from inside. ### help Should I repair the crack or replace the slab? expand\_more Repair when cracks are isolated, the slab is otherwise sound, and there is no widespread spalling. Replace when cracking runs through multiple panels with displacement, when the base has failed, or when the surface has deteriorated across most of the area. About half the slabs we are called out to replace can be repaired instead. ### help How long does crack repair take? expand\_more Most single-crack repairs are completed in a few hours. Injection cures within a day, and ports are removed and the surface ground flush at the end of the visit or the following morning. ### help Do you warranty crack repairs? expand\_more Yes. Every installation, including repairs, carries our 2-year workmanship warranty. We are licensed, WSIB-insured and carry $2M general liability. ### Still have questions?
