Driveway Cracks vs Structural Slab: How to Tell the Difference
Cracks in concrete are common, but not all cracks are the same. Some are cosmetic and harmless, while others signal serious structural issues. For Alberta homeowners and property managers, knowing the difference between driveway cracks and structural slab cracks is essential for safety and long-term property value. Identifying problems early can prevent costly repairs and ensure the integrity of the structure.
Cosmetic Driveway Cracks Explained
Driveway cracks often appear due to shrinkage during curing, surface wear, or minor settlement. These cracks are typically narrow and shallow, and while they may affect appearance, they rarely compromise structural integrity. Cosmetic cracks can often be repaired with sealants or resurfacing to prevent water infiltration and to restore curb appeal.
What Makes a Crack Structural?
Structural cracks are different because they impact the stability of the slab. These cracks are usually wider, deeper, and may show signs of vertical or horizontal displacement. They are caused by settlement, heaving from freeze thaw cycles, or foundation shifts. Structural cracks are more serious in load-bearing slabs such as garage floors, basement slabs, and commercial parkades. Unlike cosmetic cracks, they indicate that the slab is under stress and losing its structural capacity.
Signs It Is Time to Call a Professional
Certain signs suggest a crack may be structural and requires professional inspection:
Cracks wider than a quarter inch that continue to spread
Slabs that have shifted vertically or are uneven
Continuous cracks that run across the entire surface
Evidence of water infiltration or soil erosion beneath the slab
Cracks forming near structural supports in garages or parkades
These issues should not be ignored, as they can quickly worsen without intervention.
Risks of Ignoring Structural Slab Damage
Leaving structural cracks untreated creates several risks. Compromised slabs can affect the stability of connected structures, create trip hazards, and allow water to penetrate, leading to further erosion and damage. In commercial settings like parkades, ignored cracks may lead to costly closures and liability issues. In homes, they can affect foundation integrity and reduce property value. Repairing cracks early is far more affordable than replacing entire slabs later.
Structural Slab Repairs for Parkades and Commercial Spaces
Parkades and other commercial slabs are especially vulnerable due to heavy loads and exposure to moisture. Professional concrete contractors use specialized repair techniques such as epoxy injections, reinforcement, and slab replacement to restore safety and performance. Routine inspections are critical in these environments, as early detection prevents damage from escalating into major structural failures.
