Colorado Springs sits at roughly 6,035 feet elevation on the eastern edge of the Rockies, where temperature swings from sub-zero winter nights to 90-degree summer afternoons stress concrete surfaces hard. The city logs more than 70 freeze-thaw cycles per year, and El Paso County road crews apply magnesium chloride de-icer from October through March. That mag chloride tracks into garages on vehicle tires, where it sits on bare concrete and accelerates surface scaling. Neighborhoods like Briargate, Northgate, Flying Horse, and the Broadmoor area each have large attached garages that take the full brunt of this cycle every season.
