Cold Weather Concrete Forming: What Every Contractor Should Know
As temperatures drop, the risks for concrete pours rise. Cold weather doesn’t just affect jobsite comfort—it impacts curing times, structural integrity, and project timelines. To stay on schedule and ensure quality results, contractors need to adjust their approach during the colder months.
At Forming America, we’ve helped contractors nationwide tackle winter pours with the right forming systems and strategies. Here’s how to keep your jobsite productive and your concrete performing—even when it’s freezing outside.
The Cold Truth About Concrete
Concrete needs warmth to cure properly. When temperatures fall below 40°F (4°C):
• Hydration slows down, delaying strength gain
• Water in the mix can freeze, causing cracking or scaling
• Formwork removal takes longer, adding delays and labor costs
That’s why cold-weather forming isn’t just about convenience—it’s about protecting your investment.
Key Tips for Cold-Weather Forming Success
1. Choose Insulated or Dense Formwork
Systems like Symons Steel-Ply are ideal for cold pours—they retain heat better than lightweight alternatives. In extreme conditions, consider using thermal blankets or heated enclosures over the forms.
2. Plan for Extended Set Times
Don’t rush form removal. Concrete will cure more slowly in low temperatures, so allow for extra time before stripping forms or loading structures.
3. Keep Formwork Dry and Clean
Moisture trapped between the form and the concrete can freeze, damaging both the surface finish and the form itself. Always clean and store your forms properly between pours.
4. Use Warm Mix Water or Accelerators
If you’re working with the concrete supplier, request warm water or chemical accelerators to jump-start hydration. Just make sure these are compatible with your mix design and application.
