Can concrete be poured in winter in Winston-Salem, NC?

(336) 608-5157Get Free Estimate

Yes. Concrete can be poured year-round in Winston-Salem and the North Carolina Piedmont, unlike asphalt which cannot be placed below about 50°F. Cold-weather concreting uses heated mixing water, accelerating admixtures, and insulating blankets to keep the slab above freezing while it gains early strength. Work slows during a hard freeze but the season does not shut down.

What changes when it is cold

Concrete cures through a chemical reaction that generates its own heat, and that reaction slows as temperature drops. The risk is not the cold itself but the slab freezing before it has gained enough strength, which permanently damages it.

How this compares to asphalt

This is the practical difference between the two materials in the Piedmont. Asphalt needs ground temperatures above roughly 50°F to compact properly, so paving here effectively ends around Thanksgiving and does not restart until spring.

Concrete has no equivalent hard stop. If you want work done between November and March in Forsyth County, concrete is generally the option that is actually available.

Is winter a good time to schedule

There is a scheduling argument for it. Contractor books are typically fuller in spring and summer, so lead times in the colder months can be shorter. The tradeoff is that a hard freeze or a wet week can push your date.

Why quotes for the same job can be far apart

Cold-weather work carries some real added cost for heated water, admixtures and blankets, so a January quote may sit slightly above the same job in June. A contractor who quotes winter work at exactly the summer price either is not planning cold-weather protection or is absorbing it, and it is worth asking which.

Common questions

What is the coldest temperature concrete can be poured in?⌄
With proper cold-weather practices concrete is regularly placed below freezing, but the subgrade must not be frozen and the slab has to be protected until it gains early strength. Below about 40°F those protections become necessary rather than optional.
Will winter concrete be weaker?⌄
Not if it is protected correctly. It gains strength more slowly, so cure times stretch, but a properly protected winter pour reaches full design strength. A slab allowed to freeze early is permanently compromised.
How long before I can drive on a winter pour?⌄
Longer than in summer. Where you might wait about seven days in warm weather, cold conditions can extend that, and the contractor should give you a specific number based on how the slab is protected.
