Calgary experiences some of the most dramatic temperature swings in Canada, and these fluctuations can take a toll on concrete surfaces. Understanding how freeze–thaw cycles work can help homeowners prevent premature cracking and maintain their investment. At Lion Heart Contractors Ltd., we design every project to resist the harsh conditions Calgary is known for.
Why Freeze–Thaw Cycles Are Hard on Concrete
When temperatures fluctuate above and below freezing, moisture inside the concrete expands and contracts. Over time, this movement can lead to spalling, surface breakdown, and cracking, especially if the concrete isn’t installed or maintained correctly.
Ways to Protect Your Concrete in Calgary
1. Proper Sealing: High-quality sealants reduce moisture absorption during winter.
2. Good Drainage: Slabs must be pitched correctly to prevent ice buildup and pooling.
3. Strong Reinforcement: Rebar grids increase durability and minimize structural cracking.
4. Avoid De-Icing Salts: Chemicals can accelerate surface damage—use sand instead.
