How We Repair Cracks In Property Foundations

Reliable Crack Repair Methods to Prevent Structural Damage and Leak

Fixing foundation cracks the right way depends on their severity, the surrounding soil conditions, and the risk of water infiltration. In Toronto and the GTA, where homes face constant freeze-thaw cycles and moisture buildup, using the right foundation repair techniques is important. If cracks have already caused moisture issues, we handle water damage restoration after foundation leaks to prevent further structural problems. We offer free at-home consultations to access the area carefully and apply the best solution to stop further damage, prevent leaks, and restore your foundation’s strength.

Best Methods for Foundation Crack Repair

Epoxy Injections – Used for structural cracks, epoxy injections bond the concrete back together, reinforcing the foundation and preventing further cracking. This is ideal for situations where foundation walls need added strength and durability.
Polyurethane Foam Injections – Best for sealing cracks that let in water, polyurethane expands to fill gaps and create a flexible, watertight barrier. This is commonly used for active leaks and areas exposed to moisture.
Interior Waterproofing Solutions – If cracks are allowing water into your basement, we install waterproof coatings and drainage systems to keep waterproof basement interiors dry and protected.
Exterior Waterproofing Membranes – When foundation walls are exposed to heavy moisture or groundwater, a durable waterproofing membrane is applied to block water intrusion before it reaches your foundation.

What Causes Foundation Cracks?

Understanding the Common Causes of Foundation Damage

Foundation problems can develop due to shifting soil, water damage, and environmental factors, leading to cracked basement walls, sinking foundations, and structural instability. Homeowners in Toronto and the GTA often experience foundation issues due to the region’s freeze-thaw cycles, heavy rainfall, and poor drainage.

Top Causes of Foundation Damage

Expanding and Contracting Soil – Certain soils, especially clay, expand when wet and shrink when dry, causing foundation movement.
Poor Drainage Around the Home – Standing water near your foundation increases pressure on basement walls, leading to cracks and leaks.
Hydrostatic Pressure – Excess groundwater buildup pushes against the foundation, causing wall bowing and water seepage.
Large Tree Roots Near the Foundation – Roots shift the soil and weaken the foundation, leading to cracking and instability.
Extreme Weather Changes – Freeze-thaw cycles cause the soil to expand and contract, putting stress on the foundation.
Leaking or broken plumbing pipes – Excess moisture from leaks can weaken foundations, cause cracks, and lead to indoor mould growth. Our mould removal experts ensure your home stays dry and safe.
