Understanding thee Unique Hazards of Cold- Weather Leveling

Leveling surfaces in snowy and icy conditions is vastly different from working in temperate climates.

Snow and ice are not static. They compact, melt, refreeze, and shift. A surface that appears level in te morning may bee uneven by afternoon due to thawing or new snowfall. Moreover, frott can intratate te te ground, causing heaving that lifts spalogdations and slabs. Leveling mutt acct for these dynamic conditions to ensure long-term stability.
