Key takeaways
- Air-entrained concrete resists freeze-thaw.
- Rock salt damages surfaces.
- Good drainage prevents ice and damage.
- Seal before winter.
What freeze-thaw does
Water gets into concrete, freezes and expands, pushing the surface apart. Over many cycles it causes scaling and cracks.
Built to resist
Air-entrained concrete contains microscopic bubbles that relieve pressure. A good base and drainage keep water from sitting.
De-icers
Rock salt and ammonium-based products damage concrete. Use sand or calcium magnesium acetate.
Seal before winter
A fresh sealer sheds water and reduces damage. Fall is a great time to reseal.
Spring checkup
After winter, rinse the surface and look for chips or new cracks.

Quick answers
Is salt really that bad?
Yes, especially on young concrete and for surfaces without sealer.
When should I pour new concrete?
Spring through fall is easiest; we pour in cooler weather with protection when conditions allow.
