Calgary and Concrete

1. Calgary’s Concrete Must Withstand Extreme Temperature Swings

Calgary can experience temperature changes of 30°C or more in a single day. Because of this, concrete used here often includes air-entraining admixtures — tiny air bubbles that help relieve internal pressure when water freezes and thaws, preventing cracking and scaling.

2. Cold Weather Concrete Pouring Is an Art

In winter, contractors use heated enclosures, warm water, and insulated blankets to keep concrete from freezing during curing. Calgary’s building codes require strict procedures to ensure proper strength gain even in sub-zero conditions.

3. Local Materials Make It Sustainable

Most ready-mix concrete in Calgary uses locally sourced sand, gravel, and limestone, reducing transportation emissions. Supplementary materials like fly ash from Alberta power plants are also used to lower the carbon footprint and improve durability.

4. Proper Drainage Is Crucial in Calgary’s Chinook Climate

The city’s rapid freeze-thaw cycles and Chinook winds mean surface drainage and sealing are key to long-lasting driveways, sidewalks, and patios. Poorly drained slabs can deteriorate quickly due to trapped meltwater refreezing.

5. Decorative and Heated Concrete Are Popular Innovations

Calgarians are increasingly choosing stamped and coloured concrete for driveways and patios — and even hydronic heated slabs that melt snow automatically, cutting down on winter shoveling and de-icing salt damage.
