Foundation Crack Sealing Winnipeg
Foundation cracks are one of the most common warning signs of structural stress and water intrusion in Winnipeg homes. While some cracks may appear minor at first, even small openings can allow moisture, soil gases, and long-term damage to develop if left untreated.
At Assured Foundations, we provide professional foundation crack sealing in Winnipeg using proven repair methods designed for our extreme climate, shifting soils, and freeze–thaw cycles. Our goal is not to hide cracks, but to permanently seal and stabilize them.
Why Foundation Cracks Should Never Be Ignored
A foundation crack is rarely just cosmetic. Over time, cracks can lead to:
Water leaks into the basement
Increased humidity and mold growth
Soil pressure worsening the crack
Structural movement and wall displacement
Higher repair costs if delayed
Many homeowners notice cracks during heavy rain, snowmelt, or when water begins seeping through basement walls or floors. These are clear signs that professional crack sealing is required.
Common Causes of Foundation Cracks in Winnipeg
Winnipeg foundations are exposed to unique stresses that increase the likelihood of cracking:
Expansive Clay Soil
Clay soil expands when wet and contracts when dry, placing constant pressure on foundation walls.
Freeze–Thaw Cycles
Water entering small cracks freezes, expands, and forces the crack wider over time.
Settlement and Soil Movement
Poor compaction, drainage issues, or changes in groundwater levels can cause foundations to settle unevenly.
Hydrostatic Pressure
Water pressure building against foundation walls pushes moisture through cracks and joints.
Concrete Shrinkage
As concrete cures, minor shrinkage cracks can form and later worsen under pressure.
Types of Foundation Cracks We Repair
Not all foundation cracks are the same. Correct repair depends on crack type, location, and cause.
Vertical Foundation Cracks
Often caused by settlement or shrinkage. These are common and usually repairable with professional sealing.
Horizontal Foundation Cracks
Typically caused by lateral soil pressure. These may indicate structural concerns and require careful assessment.
Stair-Step Cracks
Found in block or brick foundations, often related to soil movement or moisture issues.
Basement Floor Cracks
Can allow water seepage and radon gas intrusion if not properly sealed.
Cracks Leaking Water
Active leaks require immediate attention and specialized sealing methods.
Our Foundation Crack Sealing Process
At Assured Foundations, crack sealing is never a one-size-fits-all solution. Every repair begins with a thorough inspection.
1. Crack Assessment
We determine:
Crack width and length
Active vs dormant movement
Water intrusion presence
Structural vs non-structural nature
This ensures the correct repair method is used.
2. Surface Preparation
The crack is cleaned and prepared to ensure proper bonding. Loose concrete, debris, and moisture are addressed before sealing begins.
3. Professional Crack Sealing Methods
Depending on the situation, we use one or more of the following:
Epoxy Crack Injection
Restores structural strength
Bonds concrete back together
Ideal for non-moving cracks
Polyurethane Injection
Flexible and waterproof
Ideal for active leaks
Expands to fill voids
Exterior Crack Sealing
For cracks exposed to groundwater pressure, sealing from the outside prevents water entry at the source.
We do not rely on surface patching, store-bought fillers, or temporary sealants.
4. Waterproofing Integration (When Required)
If water pressure is contributing to cracking, we may recommend additional waterproofing measures to protect the repair long term.
Interior vs Exterior Foundation Crack Sealing
| Repair Location | Best Use Case |
|---|---|
| Interior crack sealing | Non-structural cracks, controlled leaks |
| Exterior crack sealing | Active water intrusion, high pressure areas |
| Combined repair | Severe or recurring crack issues |
In many cases, exterior sealing provides the longest-lasting results by stopping moisture before it reaches the foundation wall.
Why DIY Crack Fillers Often Fail
Many homeowners attempt repairs using hardware-store products or surface sealants. These typically fail because they:
Do not penetrate the full depth of the crack
Cannot withstand hydrostatic pressure
Become brittle in cold temperatures
Mask the problem instead of solving it
Professional foundation crack sealing is designed to last—not peel, shrink, or fail after one season.
Cost to Seal Foundation Cracks in Winnipeg
Foundation crack sealing costs depend on:
Crack size and location
Interior vs exterior access
Active water leakage
Structural reinforcement needs
Typical price ranges:
Interior crack sealing: $600 – $1,200 per crack
Exterior crack sealing: $1,500 – $3,500+ per crack
Multiple crack repairs: Custom pricing
Addressing cracks early is significantly more affordable than repairing water damage or structural deterioration later.
