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 LocationBest Use Case
Interior crack sealingNon-structural cracks, controlled leaks
Exterior crack sealingActive water intrusion, high pressure areas
Combined repairSevere 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.
