Basement walls in Regina develop cracks from shrinkage, settlement, and frost pressure. Most start small and stay dry. Some weep. Left unaddressed through a winter, freeze-thaw cycles widen them and water follows. Regina Concrete inspects the crack, determines if it is active or stable, and injects or seals it with the right material so it stops moving and stops leaking. The assessment is free and the repair quote is written.
A vertical hairline running down a basement wall or a small horizontal at the top of a pour looks minor in October. By March, after the freeze-thaw cycle has worked it, the crack is wider and water is coming through. What could have been sealed in a few hours becomes a wall repair.
We measure and photograph each crack, determine whether it is vertical or horizontal, active or stable, and whether it is weeping or dry. That classification drives the repair method. A dry vertical hairline gets surface sealed. A weeping crack gets polyurethane injected through ports drilled at depth. A horizontal crack that suggests pressure gets flagged for structural assessment before any injection happens.
The same discipline applies whether we are repairing one crack or a wall full of them. We tie the work into our broader basement concrete services and our foundation work. If a crack is structural, we refer to foundation repair and quote that separately.

The repair sequence
How Foundation Crack Repair Gets Done in Regina
Assess the crack on site
We measure, photograph, and classify each crack as vertical or horizontal, active or stable, dry or weeping. The classification determines the repair method and material.
Route and prepare the surface
The crack is routed to a clean profile where needed, dust and loose material are removed, and injection ports are positioned at the right spacing to reach full depth.
Inject or seal the crack
Weeping or active cracks receive polyurethane injection through the ports, which flexes and bonds at full depth. Dry stable cracks are sealed at the surface. The material matches the crack condition.
Cure, trim, and verify
After curing, ports are trimmed flush, the wall is cleaned, and the repair is inspected. If the exterior wall is exposed, we recommend pairing with foundation waterproofing.
Not all cracks are created equal
When a Foundation Crack Signals a Bigger Issue
Most foundation cracks are benign, vertical, hairline, and dry. Some are not. Horizontal cracks across a wall, stair-step patterns in block, or cracks that change width seasonally all point to the wall being pushed or pulled by external forces. That is a structural problem, not a cosmetic one.
When we encounter those patterns, we flag them immediately, refer to underpinning or structural foundation repair as appropriate, and quote that work separately. We will not inject over a structural defect.
Hairlines, horizontals, polyurethane injection, and when a crack means something bigger.
Most do, even hairline ones, because once water gets in and the freeze-thaw cycle takes over, a cosmetic crack becomes a leak. Sealing or injecting it early is much cheaper than fixing it after it has opened up.
Polyurethane is flexible, expands on contact with water, and is our default for active or weeping cracks. Epoxy is rigid and structural, used when bonding the two sides of the crack permanently is the goal. We choose based on the crack.
Yes, most cracks are injected from the inside through ports drilled into the wall, which avoids excavation. Exterior repair is reserved for cases where outside conditions are causing the crack or where pairing with waterproofing is the right call.
Usually yes. Horizontal cracks suggest the wall is being pushed by soil pressure or water; that is a structural issue and gets referred up to foundation repair. Vertical hairlines are usually just shrinkage and routine to fix.
A typical injection takes a few hours and the crack is sealed by the end of the visit. Larger or multiple cracks may take a day. The timeline is in the written quote so you know up front.

What Regina Homeowners Say About Their Crack Repairs
Hairline crack started weeping last spring. Injected from inside in one visit, sealed up properly, and it has stayed dry through the next season. Cheap and done.

They flagged one of my cracks as horizontal and recommended a structural look instead of just injecting. Could have charged me, didn't. That kind of honesty is rare.

Three vertical cracks injected in one visit. No mess, no fuss, no return leaks. Quote was firm, work was clean, ports trimmed off so you barely see them.

Classified each crack on the wall and only repaired the ones that needed it. The rest were stable shrinkage and didn't need a thing. Saved real money.
