When the walls that support your home start to crack, it’s time to take action. If ignored, foundation wall cracks widen and compromise your property’s entire structure, putting your loved ones at risk.

This is no DIY project, either. Solutions from a hardware store only provide temporary relief, and cracks will reappear soon. You need a professional foundation repair team to fix this issue permanently.

Your Groundworks expert identifies the root cause of foundation cracks and offers permanent repair solutions to prevent their return. Our patented foundation repair products protect your property from additional damage and more expensive repairs.

What Are Cracks in Foundation Walls?

Your home is only as good as its foundation walls, which bear the weight of your property and provide structural support. Cracks appear on these walls due to fluctuating soil conditions, concrete shrinkage, or other factors, eventually damaging your home’s structural elements.

Small cracks might not seem like a cause for concern. However, they will widen over time, which leads to water damage, mold, pest, and wood rot. Wide cracks also cause bowing, tilting, or buckling in your walls.

What Causes Foundation Wall Cracks?

Cracks in your foundation walls happen for various reasons

Concrete Shrinkage

Poured concrete is prone to shrinking, which creates small cracks in foundation walls. These cracks don’t increase in size much, so they pose little risk to your home’s structure.

Foundation Settlement

Foundations settle if the soil underneath them compacts or shifts. If this is the cause of your foundation cracks, you’ll need to hire a professional repair expert like Groundworks.

Clay Soils

Stagnant and pooling water after rainfall causing foundation cracks.

Expansive clay soils, common in Alberta, shrink when dry and swell when wet. These fluctuations put pressure on your foundation walls, forming cracks. Walls can also bow, lean, buckle, or tilt inward during this process.

Hydrostatic Pressure

Heavy rain or snowmelt is another common reason for foundation cracks in Alberta. If this moisture saturates the soil under your home, it will cause hydrostatic pressure. As a result, concrete walls crack, especially if drainage systems can’t effectively remove water buildup.

Poor Construction

Inadequate foundation installation, weak steel reinforcement, and inferior concrete are other causes of cracks in foundation walls.

Identifying Cracks in Foundation Walls

Recognizing the signs of foundation wall cracks prevents more significant damage to your home. Here’s what to look out for:

A large crack on the exterior of a wall of a residential home.
  • Vertical cracks
  • Horizontal cracks or stair-step patterns
  • Cracks exceeding 1⁄4 inch
  • Cracks with rust stains from exposed rebar
  • Other signs of foundation damage, such as floor gaps, uneven floors, and sticking doors and windows
  • New cracks or widening cracks

Can You Fix Cracks in Foundation Walls?

The best way to fix foundation cracks is to address the source of the damage. Crack fillers and other store-bought products are insufficient, temporary fixes that won’t solve the issue.

Groundworks recommends a whole-home approach to stabilize the foundation, including braces, anchors, foundation piers, and water drainage solutions. By stabilizing your foundation, you’ll preserve the structural integrity of your property and stop new cracks from forming.

How to Fix Cracks in Foundation Walls

Our team uses a blend of solutions when repairing foundation wall cracks in your home:

Wall Anchors

Our exclusive wall anchor system fixes cracks that appear due to clay soils or hydrostatic pressure. We install anchors in the ground outside your property that connect to steel rods running through your foundation wall. Tightening these rods counteracts exterior pressures that cause cracks and bowing.

Wall Braces

The IntelliBrace™ Wall Repair System suits cramped spaces with limited exterior access. We use this technology to close existing cracks and straighten walls.

Foundation Piers

For settlement cracks, we install push, slab, or helical piers under your foundation to stabilize and lift uneven areas.

Drainage

Our advanced interior drainage systems control hydrostatic pressure. These systems channel groundwater to a sump pump, redirecting it from your home’s structure and preventing foundational damage.

Groundworks specializes in foundation repair and perimeter waterproofing all throughout Alberta. All our proprietary products come with long-term warranties for your peace of mind.

Cory came to my house, thoroughly evaluated the situation, explained the options to me, and patiently answered all of my questions. He is amazing. There was a crack in my basement wall that needed to be repaired. Paul (I think) did a good and clean Job. The repair was scheduled and completed exactly as was described to me. Great team! I’d definitely recommend this company to others.

Excellent service. Sales was pleasant and quote was thorough enough to proceed. The crew that came out to excavate, and install the interior and exterior basement systems was absolutely top notch – their work was neat and tidy, they showed up on time, and worked hard. To top it off, they (and all the folks involved) have to be the most pleasant contractors I’ve ever dealt with – and this is house #5 for us over the years! Thank you, Basement Authority. Highly recommend.
