Why concrete fails in Ontario Freeze-thaw cycles + de-icing salt = surface scaling. The good news: it's almost entirely preventable.
1. Seal it — twice the first year A fresh pour needs a penetrating siloxane sealer applied at 30 days and again at 12 months. Then every 2–3 years.
2. Avoid salt the first winter For the first full winter after pouring, use sand only. Salt attacks the surface before it has fully cured.
3. Choose calcium chloride over rock salt After year one, calcium chloride is significantly gentler on concrete than sodium chloride (rock salt).
4. Plow with a rubber-edged blade Steel plow blades chip the surface. Snowblowers and rubber-edged plows are kinder.
5. Repair small cracks immediately A hairline crack in October becomes a 1/4-inch separation by April. Polyurethane crack filler is a $20 fix.
