Concrete Slab Repair & Replacement in Ottawa
Long-Lasting Solutions for Cracked, Uneven & Deteriorating Concrete
Cracked, uneven, or deteriorating concrete doesn’t always mean your garage or basement floor needs to be replaced. ProCore assesses the condition of your slab and the factors contributing to the damage before recommending the right repair.
Whether your slab needs targeted crack repair, partial repouring, or complete replacement, we focus on addressing the underlying issues and delivering durable results that restore the stability and usability of your concrete floor.
Professional Concrete Slab Repair for Your Home
Concrete slabs are built to provide a stable, durable surface, but cracking, settlement, and deterioration can develop as the slab and the ground beneath it are exposed to changing conditions.
A small crack or damaged area does not always mean the entire slab needs to be replaced. However, you should not simply cover or patch concrete damage without considering why it developed. Cracks can widen, sections can keep moving, and water can enter through openings if the conditions contributing to the damage remain.
ProCore assesses the condition of the slab, the pattern and extent of the damage, and potential contributing factors before recommending a repair. When the existing concrete remains in suitable condition, targeted repairs may be enough to address the affected area and extend the life of the slab.
Signs Your Concrete Slab May Need Repair or Replacement
Changes in a concrete floor can provide useful clues about what is happening to the slab or the material supporting it. Signs worth having professionally inspected include:
- Cracks that continue to grow, deepen, or widen
- Uneven or sunken sections of concrete
- Areas of the slab that are heaving
- Crumbling, flaking, or deteriorating concrete
- Water entering through cracks
- Sections separating from surrounding concrete
- Damage around joints or slab edges
- Significant or widespread surface deterioration
- Previous repairs that continue to crack or fail
Not every crack indicates that a slab needs to be replaced. We examine the location, pattern, and severity of the damage, along with evidence of movement or moisture, to help determine whether the concrete can be repaired or whether more extensive work is appropriate.
Our Concrete Slab Repair & Replacement Services
ProCore provides repair and replacement options for residential concrete slabs based on the type of damage, extent of deterioration, and conditions affecting the concrete.
Garage Slab Repair & Replacement
Garage floors can develop cracks, uneven sections, settlement, and surface deterioration over time. Vehicle loads, moisture, drainage conditions and movement beneath the slab can all influence how the concrete performs.
ProCore assesses the damaged areas and surrounding slab to determine whether localized repairs are appropriate or whether part or all of the garage floor should be replaced.
Basement Floor Slab Repair & Replacement
Cracks and uneven areas in a basement floor can develop because of settlement, movement beneath the slab, moisture conditions, or deterioration of the concrete itself.
Before repairing a basement slab, ProCore assesses the cracking and surrounding conditions to determine whether the damage is localized or connected to a broader issue.
Concrete Crack Stitching
Concrete crack stitching is a repair method used to reinforce certain cracks and help reconnect concrete across the damaged area.
Whether crack stitching is appropriate depends on the type of crack, the condition of the surrounding concrete, and whether ongoing movement is present. ProCore assesses these factors before deciding whether stitching or another repair method better suits the slab.
ProCore assesses the damaged areas and surrounding slab to determine whether localized repairs are appropriate or whether part or all of the garage floor should be replaced.
Polyurethane & Epoxy Injection
Polyurethane injection may be used when sealing a crack against water infiltration is a key part of the repair. Epoxy injection may be appropriate for certain concrete cracks where a rigid repair is required to bond the damaged area.
Because polyurethane and epoxy serve different purposes, we select the material based on the crack and the underlying issue, rather than treating every crack the same way.
Partial & Complete Concrete Repours
Not every damaged slab needs to be removed completely. When deterioration is limited to a particular area, the affected concrete may be removed and repoured, while suitable portions of the existing slab remain in place. For more extensive damage, complete slab replacement may be the better long-term solution.
Depending on the site conditions, preparation may include grading, compacting the base, considering drainage and moisture management, and incorporating appropriate reinforcement before the new concrete is poured and finished.
ProCore determines whether partial or complete replacement is appropriate based on the condition of the existing slab and the factors contributing to its deterioration.
What Causes Concrete Slab Damage in Ottawa?
Concrete slabs in Ottawa are exposed to significant seasonal changes. Cold winters and repeated freeze-thaw cycles can affect both the concrete and the ground supporting it.
Drainage and moisture conditions also matter. Water collecting around or beneath concrete can affect the supporting soil, while water entering existing cracks can worsen deterioration as temperatures rise and fall. Other factors include aging concrete, improper installation, insufficient reinforcement, and deterioration from years of use and exposure.
Different conditions can produce similar-looking cracks or movement; that’s why we emphasize understanding the cause of the damage to select the right repair.
Concrete Slab Repair vs. Replacement: Which Do You Need?
A cracked concrete floor does not automatically need to be torn out and replaced. The right approach depends on how much of the slab has been affected, whether it remains stable, and what caused the damage.
Concrete Slab Repair
- Localized cracking
- Minor concrete damage
- Individual deteriorated sections
- Slabs that remain otherwise stable and in suitable condition
- Problems that can be corrected without removing the entire slab
Concrete Slab Replacement
- Extensive or widespread cracking
- Severe settlement
- Significant frost heave or movement
- Widespread concrete deterioration
- Major problems with the slab or supporting base
- Slabs where previous repairs have repeatedly failed
ProCore assesses the slab and the conditions contributing to the damage before recommending either approach. The objective is to complete the work the concrete actually requires rather than replacing a slab that can reasonably be repaired or repeatedly patching one that requires a more comprehensive solution.
Our Concrete Slab Repair Process
1. Concrete Inspection
We inspect the slab, cracks, damaged areas and surrounding conditions to understand the extent of the problem.
2. Identify the Cause of Damage
We look for conditions that may be contributing to the damage, including settlement, moisture, frost movement, drainage issues or changes in the supporting soil.
3. Recommend the Right Repair
Based on what we find, we explain whether crack repair, injection, crack stitching, partial repouring or complete slab replacement is appropriate and why.
4. Complete the Repair or Replacement
Our team completes the recommended work using methods and materials suited to the slab's condition. For targeted repairs, this may involve crack injection, stitching, or replacing damaged sections.
When slab replacement is required, we remove the affected concrete and prepare the underlying base before pouring the new slab. Depending on the project, this may include base preparation and compaction, drainage and moisture considerations, and appropriate reinforcement. The new concrete is then poured and finished to provide a stable, durable floor surface.
5. Final Inspection
We review the completed work and provide recommendations to protect the repaired or replaced concrete going forward.
Why Choose ProCore for Concrete Slab Repair?
Experienced Structural Repair Specialists
Concrete in Ottawa and the surrounding region is exposed to cold winters, freeze-thaw cycles, changing soil conditions and seasonal moisture.
ProCore understands how these conditions can contribute to settlement, frost movement, cracking and deterioration. We consider the concrete itself as well as soil, drainage and foundation-related conditions that may be contributing to the problem.
Repair Before Replace
When the slab remains in suitable condition and the problem is localized, repairing the affected area can provide a practical, durable solution without removing concrete that is still performing properly.
Our recommendations are based on the actual condition of the slab and the cause and extent of the damage.
Solutions for the Cause, Not Just the Crack
A crack is often the visible result of something happening to the concrete or beneath it. Settlement, frost movement, water and other conditions can all contribute to cracking or displacement.
ProCore looks beyond the visible damage to determine whether another condition needs to be addressed as part of the repair. This helps reduce the likelihood of simply repairing a crack only for the same problem to return.
Support for Related Foundation & Moisture Issues
When the problem extends beyond the concrete floor, ProCore can assess related conditions and provide appropriate foundation stabilization, structural repair, foundation crack repair and waterproofing services.
This means our repair strategy accounts for the home’s overall condition rather than treating the slab as an isolated surface.

How do I know if I need foundation crack repair?
What is the process for repairing foundation issues?
What is considered structural damage?
Structural damage affects components that support or stabilize the home, such as the foundation, load-supporting beams or foundation walls. A professional assessment can distinguish structural concerns from cosmetic deterioration.
How do I know if a foundation crack is structural?
The size, direction and location of a crack, whether it is changing and the condition of the surrounding structure all matter. Rather than judging a crack by appearance alone, have it assessed if it is widening, accompanied by movement or otherwise concerning.
Can structural damage get worse over time?
Some structural problems can progress if the condition causing movement or deterioration continues. Early assessment helps determine whether a problem is stable or requires corrective work.
Can sagging floors be repaired?
Is foundation underpinning always necessary for settlement?
No. The appropriate repair depends on the cause and extent of the movement. Underpinning is one method of stabilizing a foundation, but it is not required for every crack or settlement concern.
How long do structural repairs take?
Timelines vary according to the repair method, extent of the affected area and accessibility. ProCore can provide a clearer scope and expected timeline after assessing the property.
What causes concrete slabs to crack?
Concrete can crack because of shrinkage, settlement, soil movement, frost heave, moisture conditions, aging, inadequate support or other factors. The crack pattern and surrounding conditions can help determine what may be causing the problem.
Can a cracked garage slab be repaired?
Yes, many cracked garage slabs can be repaired without replacing the entire floor. Whether repair is appropriate depends on the severity of the cracks, whether sections of the slab have moved or settled and the overall condition of the concrete.
Can cracks in a basement floor be repaired?
Yes. Different repair methods can be used depending on the crack and what caused it. Basement floor cracks should also be assessed for moisture infiltration, settlement or other conditions that may need to be addressed as part of the repair.
