Our Basement Crack Repair Services
We provide complete crack repair solutions tailored to your basement. Each project addresses your specific crack type and water entry point.
Basement Crack Injection
We use epoxy and polyurethane injection to permanently seal cracks and stop water intrusion. Epoxy restores structural strength. Polyurethane expands to fill voids and stop active leaks. This is our most requested service. Most crack injections are completed within 1-2 hours per crack.
Basement Foundation Crack Repair
We repair structural cracks in foundation walls to restore strength and stability. Horizontal or stair-step cracks wider than 5mm indicate foundation movement. These require immediate attention. No excavation needed for most repairs.
Basement Wall Crack Repair
We fix vertical, horizontal, and stair-step cracks in concrete walls caused by soil pressure and settlement. Vertical cracks are common and often less urgent. Horizontal cracks are serious and need prompt repair. Concrete crack repair from the interior only.
Basement Floor Crack Repair
We repair cracks in basement slabs to prevent moisture intrusion and structural weakening. Floor cracks allow radon gas, moisture, and soil gases to enter your home. Sealing them improves indoor air quality.
Crack Sealing & Waterproofing
We seal non-structural cracks and apply waterproof coatings to prevent future leaks. For active leaks, see our basement waterproofing systems page. Minimal disruption to your home.
Basement Drainage Solutions
We install drainage systems to keep your basement dry and prevent recurring issues. Interior weeping tile, sump pumps, and drain boards channel water away before it enters. Ideal for homes with chronic dampness.
What Causes Basement Cracks
Understanding the cause helps us design permanent repairs that address the root problem.
- Soil pressure against foundation walls Wet soil expands and pushes against foundation walls, causing bowing and cracking. This is common in Toronto's clay soils.
- Freeze-thaw cycles Water enters cracks, freezes, expands, and makes cracks wider. Toronto experiences 40+ freeze-thaw cycles each year.
- Poor drainage around foundation Downspouts discharging next to the house or missing weeping tiles direct water toward your foundation instead of away.
- Hydrostatic pressure buildup Groundwater pushes against basement walls and floors with significant force, forcing water through any opening.
- Natural settling of the building Minor vertical cracks from settling are common. But anything wider than 5mm needs professional attention.

Signs You Need Basement Crack Repair
Ignoring these signs leads to mold, structural damage, and much higher repair costs.
Water leaking through walls or floors – Active water entry during or after rain. Most urgent sign.
Visible cracks in foundation – Any crack wider than 1mm should be evaluated. Horizontal cracks are most serious.
Damp or musty basement smell – Indicates chronic moisture even if you don’t see standing water.
Mold or mildew growth – Black, green, or white growth on walls, floors, or stored items.
White powder (efflorescence) on walls – Mineral deposits left by evaporating water. Indicates chronic moisture movement.
Pooling water after rain – Standing water on basement floor. Drainage system likely failed.
Bowing or leaning walls – Critical sign of foundation failure. Emergency repair required.
Our Crack Repair Process
01.
Inspection & Crack Analysis
We evaluate crack width, orientation, location, and whether the crack is active or dormant.
02.
Identify Structural vs Non-Structural Cracks
Not all cracks need injection. We identify which cracks need repair and which can be monitored.
03.
Surface Preparation
The crack area is cleaned, and injection ports are installed at regular intervals along the crack path.
04.
Injection or Sealing Method Selection
Epoxy for structural strength. Polyurethane for active water leaks. Sealant for hairline cracks.
05.
Crack Repair
Epoxy or polyurethane is injected from bottom to top until the crack is completely filled. Most repairs take 1-2 hours per crack.
06.
Final Inspection
We verify the crack is sealed, test for moisture, and provide photo documentation.
