Foundation crack repair is the service Dryshield uses to stop leaks and restore the integrity of poured concrete foundation walls. In Toronto and the GTA, we repair leaking foundation cracks using professional crack injection (polyurethane for active leaks and epoxy for structural cracks), with a clear recommendation based on the crack type and where water is entering. Every job starts with a full inspection so we can confirm the cause, recommend the correct repair, and help prevent the crack from becoming a recurring basement leak.

Understanding the Causes of Basement Cracks and Foundation Crack Repair.
Most foundation cracks are caused by normal settlement and outside water pressure around the foundation. In Toronto-area homes, common contributors include soil movement, freeze–thaw cycles, and repeated water pressure against the foundation wall during heavy rain and spring melt. A crack can become a basement leak when outside water finds that entry point.
Dryshield focuses on the repair method that matches the crack type (leaking vs structural) so the foundation crack repair holds long-term.
How Much Does Foundation Crack Repair Cost in Toronto?
Foundation crack repair cost depends on the crack length, crack type (leaking vs structural), wall access, and whether one or multiple cracks require repair. Minor foundation crack repairs commonly range from $750 to $1,500 per crack for residential poured concrete foundations, depending on the scope of work.
After a free inspection, Dryshield provides a clear written estimate and the recommended repair method for your foundation crack.
Foundation Crack Repair Methods We Use
Dryshield recommends the repair method based on the crack type and whether the crack is actively leaking.
• Polyurethane crack injection (for leaking cracks)
Used to stop active water entry through foundation wall cracks. This method is commonly recommended when a basement leak is coming through a vertical crack line.
• Epoxy crack injection (for structural cracks)
Used when the crack requires a rigid structural repair approach. This method is selected when the goal is to restore strength in the cracked area.
If the inspection shows that outside water pressure and poor drainage are contributing to recurring leaks, Dryshield may also recommend basement waterproofing services that address the source of water against the foundation wall.
How Can You Maintain a Healthy Foundation and Basement?
Preventative maintenance is key to extending your foundation’s lifespan and avoiding costly repairs. Here are essential tips:
- Ensure Proper Drainage: Grade the soil around your home to direct water away from your foundation. Keep gutters clean and downspouts well-maintained to prevent water from pooling against your basement walls.
- Conduct Regular Inspections: Frequently check your foundation for visible cracks, water leaks, or signs of movement. Early detection of problems allows for prompt foundation crack repairs and basement waterproofing.
- Control Water Exposure: Proper basement waterproofing prevents moisture infiltration that can weaken your foundation. Invest in interior and exterior waterproofing services to protect your basement from water damage.
- Monitor Tree Roots: Trees planted too close can exert pressure on your foundation and cause cracks. Maintain a safe distance or remove problematic trees to safeguard your foundation and basement walls.
DryShield offers expert foundation maintenance services to keep your basement dry and your foundation strong.

FAQ
What is the most dangerous type of foundation crack?
Horizontal cracks are the most concerning because they indicate that the foundation wall is bowing inward due to excessive soil pressure.
Do foundation cracks always mean the house is sinking?
No. Many cracks are caused by soil expansion and contraction or the weight of the house settling into the ground, which is normal for most structures.
How can I tell if a crack is horizontal or vertical?
Vertical cracks run up and down (often diagonally). Horizontal cracks run side-to-side along the mortar joints or through the middle of the concrete.
What are carbon fiber straps and when are they used?
Carbon fiber straps are used to reinforce foundation walls that are bowing or have structural cracks. They provide immense strength to prevent further movement.
How does soil type affect foundation cracks?
Clay-rich soils expand when wet and shrink when dry, putting significant “push-and-pull” stress on foundation walls, which often leads to cracking.
Can I ignore a hairline foundation crack?
It’s best not to. Even a hairline crack can allow moisture and radon to enter. It’s cheaper to seal a small crack now than a large one later.
What is “piers” or “underpinning” in foundation repair?
If a foundation is sinking, steel piers are driven deep into the earth to support and lift the foundation back to its original level.
Will fixing my foundation crack stop my doors from sticking?
If the sticking doors are caused by foundation movement, a structural repair can often help realign the frame, though some door adjustments may still be needed.
Does foundation repair come with a warranty?
Yes, DryShield offers comprehensive warranties on our foundation repairs, providing peace of mind for as long as you own the home.
Can landscaping cause foundation cracks?
Yes. Large trees planted too close to the home can suck moisture out of the soil, causing it to shrink and the foundation to settle.
How do you repair cracks in a stone or block foundation?
Stone and block foundations are usually repaired using “re-pointing” (replacing mortar) or interior drainage systems, as injection is less effective on porous blocks.
