What Causes Foundation Cracks?

Cracks can form due to natural settling, shifting soil, freeze-thaw cycles, or hydrostatic pressure — all common issues in the GTA’s climate. While not all cracks are structurally dangerous, many become pathways for water to seep into your home, leading to:

  • Damp basements

  • Mold and mildew

  • Wall and floor damage

  • Reduced property value


How We Fix Foundation Cracks

Our crack repair process is designed for long-term durability and moisture protection, whether you're dealing with interior or exterior problems:

1. Site Evaluation

We begin with a thorough inspection of your foundation — inside and out — to identify all signs of cracking and assess potential water entry points.

2. Surface Prep & Cleaning

We clean the affected area to ensure strong adhesion for the repair materials, removing dust, debris, and any loose material.

3. Crack Sealing or Injection

For interior repairs, we typically use polyurethane or epoxy injections, which fill the crack deep within the wall and cure to form a flexible, waterproof seal.

4. Exterior Waterproofing (If Required)

If cracks are severe or persistent, we may excavate the exterior, repair the crack from the outside, and apply a rubberized waterproof membrane to keep water out permanently.

5. Clean Finish

Once the work is complete, we restore the area to a neat, professional finish — leaving your home protected and ready for any season.
