Foundation Crack Repair

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.

Common signs you may need foundation crack repair include:
• Visible cracks on poured concrete foundation walls
• Basement leaks coming through a vertical crack in the foundation wall
• Water seepage at a crack line during heavy rain or spring melt
• Recurring wet basement conditions in the same area of the wall
• Crack edges that appear to widen or show repeated moisture staining

If you notice any of the signs above, foundation crack repair is best handled early to stop water entry and prevent the problem from spreading.

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.

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 $500 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.

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.

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.
