Calgary's freeze-thaw cycle is brutal on concrete. With temperatures swinging from −30°C to +30°C within a single season, residential and commercial concrete in Calgary takes punishment that most other Canadian cities simply don't see. Knowing when to call a professional isn't guesswork — it's pattern recognition.
Surface Spalling Across Your Driveway or Patio
Flaking and pitting are early signs of delamination. Once moisture penetrates Calgary's freeze-thaw cycle, the damage compounds fast. This is not a seal-and-forget situation. Surface spalling left untreated rapidly escalates into structural compromise requiring full slab replacement.
Cracks Wider Than 6mm
Hairline cracks are cosmetic. Structural cracks are not. If you can fit a pencil in it, it needs professional assessment. Patriarch Construction Inc. — Concrete Calgary recommends an annual crack audit on any slab over 5 years old.
Uneven or Sunken Slabs
Settlement happens when sub-base material erodes — a common issue in Calgary's clay-heavy soil zones. Uneven slabs are a trip hazard and a liability. Mudjacking or slab replacement may be required depending on severity.
Drainage Pooling Near Foundation Walls
Improperly pitched concrete directs water toward your foundation. Calgary's spring melt makes this a critical failure point. Water intrusion near foundations can lead to basement flooding and structural damage costing tens of thousands.
Deteriorating Garage Floors
Chemical exposure from road salt tracked in off Calgary roads accelerates concrete breakdown. Epoxy coating or full resurfacing may be required to restore structural integrity and prevent further delamination.
Crumbling Curbs or Exposed Aggregate Loss
Loss of aggregate at edges signals the concrete mix has failed or was improperly finished from the start. This typically indicates sub-standard installation that will continue to worsen through every freeze-thaw cycle.
