According to Environment Canada climate normals, Calgary experiences over 100 freeze-thaw cycles annually. Each cycle forces water into micro-cracks, freezes it (expanding roughly 9% in volume), then thaws it widening those cracks every time. Chinook winds compound the problem by swinging temperatures 15–20°C within hours, stressing concrete far beyond what it endures in cities with more stable winters.

Below the surface, Calgary’s clay-heavy expansive soil shifts dramatically between wet and dry seasons. That movement pushes slabs upward, pulls them apart, and creates the uneven surfaces Calgary homeowners know too well. Concrete Star’s founder, Ned, a concrete specialist with over 15 years of experience in Calgary-area residential and commercial projects, built the company’s repair methodology around these exact Calgary-specific conditions.
