Calgary’s climate punishes concrete unlike anywhere else in Canada. Chinook winds can swing temperatures 20°C in a single day, triggering aggressive freeze-thaw cycles that crack and heave garage slabs dozens of times each winter. This constant expansion and contraction breaks down even well-poured concrete within 10–15 years.
Beneath the surface, Calgary’s expansive clay soils absorb moisture and swell, then shrink during dry Alberta summers. That soil movement pushes garage slabs upward, creating uneven surfaces and structural cracks. Homes built in newer subdivisions like Evanston, Walden, and Seton often sit on backfill that hasn’t fully compacted — accelerating settlement and cracking within the first 5–8 years.
- Hairline and structural cracks — from freeze-thaw cycling and soil movement
- Slab heaving and settling — caused by Calgary’s expansive clay soils
- Spalling and surface flaking — triggered by road salt, moisture, and deicing chemicals
- Pitting and scaling — common in garages where snow-covered vehicles drip salt-laden water daily
- Control joint deterioration — weakened joints that allow moisture infiltration
- Uneven or sunken sections — from subgrade washout or poor original compaction
If you’ve spotted any of these in your garage, Concrete Star can diagnose the root cause and recommend the right fix — not just a patch that fails next spring.
Our Garage Floor Repair Process (Step-by-Step)
Crack injection and filling — using flexible epoxy resin or polyurethane that moves with Calgary’s temperature swings.
Concrete slab lifting — polyurethane foam injection raises sunken sections without full replacement.
Surface restoration — self-leveling compound and polyurea coating systems restore damaged surfaces to better-than-original condition.
Full-section replacement — when damage extends beyond repair, Concrete Star removes and repours affected sections with proper reinforcement and vapor barriers.
Most Calgary garage floor repairs range from $500 to $3,500, depending on damage severity and repair type. Crack filling typically costs $300–$800. Slab lifting with polyurethane foam runs $1,000–$2,500 for a standard two-car garage. Full surface restoration with grinding and coating falls between $2,000–$5,000.
