Injection ports along a sealed basement crack

## Why Foundation Cracks Leak

Poured concrete foundations crack as they cure and as the house settles. Most of these are thin vertical **hairline cracks**. They do not matter until water finds them. When the soil outside is saturated after snowmelt or heavy rain, **hydrostatic pressure** pushes water through the crack and into your basement.

## Types of Foundation Cracks

| Crack | What it usually means | Typical repair |
| --- | --- | --- |
| Hairline vertical | Shrinkage, normal | Polyurethane injection if leaking |
| Wider vertical | Settlement | Injection, monitor width |
| Stair-step (block) | Settlement or pressure | Assessment, possible bracing |
| Horizontal | Soil pressure, bowing | Structural assessment |

## How Trenchless Injection Works

We clean the crack, set injection ports along it and seal the surface. Then we inject **polyurethane**, which expands and stays flexible, or **epoxy**, which bonds and adds strength, starting at the bottom and working up until resin comes out of the next port. That tells us the crack is filled through the wall. The water path is closed from the inside, with no excavation.

Questions We Hear Every Week

## Foundation Crack Repair FAQs

How much does foundation crack repair cost in Toronto?

Foundation crack repair in Toronto runs $800 to $12,000. Most leaking cracks are sealed with trenchless interior injection in a single visit; excavation is only recommended when injection will not hold.

What is trenchless crack injection?

It is a repair done from inside the basement. Ports are set along the crack and resin is injected until it fills the crack through the full wall thickness, sealing the water path without digging.

Polyurethane or epoxy: which is better?

Polyurethane is flexible and ideal for sealing leaks. Epoxy is rigid and used where a crack needs structural bonding. We choose based on the crack.

Are foundation cracks normal?

Hairline vertical shrinkage cracks are common in poured concrete. They become a problem when they leak or widen. Horizontal and stair-step cracks deserve a closer look.

Can you fix a crack in a finished basement?

Yes. We remove only the drywall or panelling needed to reach the crack, inject it and you or your contractor can close it up.

Can a leaking crack be fixed in winter?

Yes. Interior injection works year-round.

When is excavation needed?

When the wall is moving, when cracks are in block walls that injection will not seal, or when below-grade waterproofing has failed broadly.

Do you guarantee the repair?

Yes. Sealed cracks come with a written warranty.
