Foundation Repair & Crack Injection
Leaking and structural foundation cracks repaired at the source. Injection and full foundation repair without tearing out your basement.
Almost every foundation in the GTA has a crack somewhere. Concrete shrinks as it cures, houses settle, and Ontario freeze-thaw cycles work on every weakness. The question is never whether cracks exist, it is which ones matter.
TCR Pro has handled foundation crack repair in Toronto and across the GTA since 1998. We repair cracks at the source, restore deteriorated foundation walls, and tell you plainly when a crack is cosmetic and needs nothing at all.

Repair and warranty
Our crew repairs, resurfaces or waterproofs, cleans up the site and backs the work with a written warranty.
Structural vs cosmetic cracks
Most foundation cracks are shrinkage cracks: narrow, roughly vertical and harmless to the structure. They still matter, because even a hairline crack is a highway for water into your basement.
Some cracks deserve more respect. Wide or widening cracks, horizontal cracks and stair-step cracking in block walls can signal pressure or movement, and they need a proper assessment before anyone talks about cosmetic fixes.
We inspect the crack, the wall and the water evidence around it, then match the repair to what is actually happening. No scare tactics, no upselling a full system where an injection will do.
Crack injection, done properly
Basement crack injection fills the crack through the full thickness of the wall, not just the surface. The material bonds inside the crack and seals it against water permanently.
A surface smear of hydraulic cement is not a repair. It hides the crack for a season or two and fails, which is why we inject or structurally patch every crack we treat, and why the work carries our written workmanship warranty.
Beyond cracks: full foundation repair
Cracks are only part of the story. We repair spalled and deteriorated foundation walls, restore concrete that is breaking down at the surface, and re-parge exposed foundation walls so they shed weather instead of absorbing it. Our dedicated parging service covers that finishing layer in detail.
Where the exterior side of the wall needs attention, we excavate, repair and protect it with a waterproof membrane. Foundation repair in Toronto homes rarely means replacement: in most cases no permits or drawings are needed, because we restore what is there.
When a crack means a water problem
If a crack has been leaking for a while, the crack may be only the visible symptom. Damp walls, efflorescence or a musty basement point to water management issues that injection alone will not solve.
In those cases we look at the basement as a system. Our basement waterproofing services pick up exactly where crack repair ends, and one inspection covers both.
Signs a foundation crack is leaking
A crack does not need visible water to be an active leak. Look for a damp streak below the crack after rain, white efflorescence tracing its path, or rust staining around tie holes nearby.
Peeling paint, a musty corner or flooring that lifts near one wall all point to moisture finding its way through. In finished basements the crack itself is usually hidden, and these secondary signs are all you get.
If any of this sounds familiar, photograph what you can see and send it over. Diagnosing a crack from good photos is often enough for an honest first answer and a free estimate.

Frequently asked questions
Most cracks in GTA foundations are shrinkage cracks: narrow, vertical and not a structural threat, though they can still leak. Wide cracks, horizontal cracks or stair-step patterns in block walls deserve a professional look. Send us a photo and we will tell you honestly which kind you have.
A single crack injection is one of the most affordable repairs in the trade, far cheaper than waiting until the wall or the basement finishes are damaged. Price depends on crack length, wall thickness and access. The estimate is free and we confirm it on site.
Usually yes. Most leaking cracks are injected from inside the basement, filling the crack through its full depth with no digging. Excavation only enters the picture when the wall itself is deteriorating or the exterior side needs membrane protection.
A properly injected crack is filled through the entire wall, not surface-patched, so the original crack is sealed for good. Concrete can always move and crack elsewhere, which is why we inspect the whole wall and tell you what we see, not just the crack you called about.
