It would be wonderful if certain projects could be postponed or completed indoors once the cold weather arrives. Unfortunately, that is not how the construction industry works. There are many professional contractors who have to be outside regardless of the weather when there is a project deadline.

Whether you are a full-time contractor or a seasonal contractor, the following tips can help you when you encounter your next concrete pour in freezing temperatures. Cold weather conditions are defined as average daily high temperatures that do not rise above 40 degrees Fahrenheit, and the air temperature does not rise above 50 degrees in a 24 hour period.

Site Preparation

It is essential that you prepare the site prior to pouring the concrete. This means that standing water, ice, and snow will need to be removed from the area you are working in.

Site preparation can include similar strategies used in the removal of water, snow, and ice on roadways. Salt, brine or another type of mixture that can quickly melt frozen liquid can be used. However, concrete should never be poured on the ground when it is frozen.

Pour Concrete During The Warmest Time Of The Day

When the temperatures are hovering around 32 degrees Fahrenheit for most of the day, it can be challenging to determine the best time of day to pour the concrete. Most contractors prefer to pour concrete during the daylight hours so they can take advantage of the heat that is created by the sun. Click here for more information.

Keep Concrete Warm

Just like you want to pour concrete during the warmest temperatures possible, you also want to ensure that the concrete mixture you are pouring remains warm as well. It will be impossible to pour concrete that is frozen, and this could delay your project by hours or even days.

The Best Tips For Pouring Concrete In Temperatures That Are Below Freezing

Make Sure There Is A Minimal Amount Of Water In The Concrete Mixture

A concrete mixture is created when the concrete powder is combined with water. An adequate amount of water must be maintained in the mixture in order to achieve a workable concrete mixture. Also, keep in mind that the water used should be room temperature or warmer.

Embedded Items Should Be Warm

Any items that will be embedded in the concrete should also be warm. Some of the most commonly embedded items in concrete are:

  • Wire
  • Wire mesh
  • Rebar

These items must be warmed prior to coming into contact with fresh concrete.

A Fresh Concrete Pour Must Be Protected From Freezing Temperatures

Once the concrete has been poured, the concrete will need to be protected from the freezing temperatures for at least 72 hours. The concrete can be protected through several methods including:

  • Heaters
  • Insulated blankets
  • Loose hay
  • Insulated forms

Be sure all of the corners and protruding rebar are also covered.

Prevent Water Accumulation For One Week

After the concrete slab has been completely poured, the concrete slab will need to remain dry for a period of seven days. By preventing water, ice or snow to accumulate on the fresh slab, the concrete will be able to cure effectively. It will also reduce the chances of shrinkage and surface cracks.

Freezing temperatures can be brutal, especially when you are trying to pour concrete. The good news is that these tips will help you have a successful, completed and error-free outdoor construction project.

Will concrete cure below freezing? The simple answer to that question is no. Yet there are workarounds. While construction companies would prefer to hold off on concrete until warmer temperatures, they have to meet demands. That being said, there are heaters that can be used to keep the concrete warmer as it cures. The curing period for concrete is very important because it has to get its strength. Visit: for more information.

If you try to cure concrete driveways during temperatures below 40 degrees, and without a heater, it’s not going to happen. Do you own a construction company? Maybe you’ve just got one project planned, and you want to get going with it soon. Whatever the case may be, you’re going to need to make sure that you address any temperature concerns.

Will Concrete Cure Below Freezing And How Is It Done?

If you don’t yet have the heaters needed for curing concrete in cold weather, you’re going to want to get them so that you can get the job done. If the weather is too cold, the concrete will not cure at all. If the temperature is below 50 but above 40, the concrete will cure, but very slowly. That’s something you’re going to have to think about based on the forecast.

You know as well as I do that temperatures often fluctuate more than 10 degrees throughout any given day. And we also know that the forecast isn’t always correct. The meteorologists do the best they can based on the information they have. That being said, you want to be prepared ahead of time when you’re going to be curing concrete.

Go by the low temperature for the day, and look at the expanded forecast based on how long the concrete is going to take to cure. Think about whether or not you will neat those heaters and get them in advance. If you are going to be taking on multiple projects, then you will be using those heaters time and time again.

If you’re only taking on one project, then you’re likely not going to want to invest in the heaters to get the job done. Instead, you will probably just want to wait to complete the do-it-yourself project in warmer weather. And if you are a homeowner that is counting on a contractor, now you know the answer about whether or not concrete can set in freezing weather.

Will Concrete Cure Below Freezing And How Is It Done?

Technically, the answer is no, but they have a way of working it out. They will use heaters, and if you’re uncertain about what’s going down, you can definitely ask about the heating aspect of the operation ahead of time. You want to be sure that everything is done correctly.

You don’t want any thermal cracking going on, that’s for sure. What you want is for the concrete to cure properly and on time. You don’t want the temperatures interfering or the costs going up for your project just because it is taking the concrete longer to cure and get its strength. You want to be sure that you are going to have great looking concrete.

What happens to concrete if it freezes? Many homeowners and business owners have that question. You might be thinking that there are plenty of concrete driveways and concrete buildings in areas with cold climates, so what gives? Does the concrete have to be installed a certain way, or is there extra maintenance you have to worry about. You could be thinking you have to worry about it cracking more often. Well, let’s take a closer look at the question and unpack the answer.

One thing you have to think about is new concrete. Newer concrete has to get its strength. The recommendation is 500 PSI. That may sound funny, but without that strength, the concrete can sure freeze. When that happens, thermal cracking can occur. So people planning to pour concrete driveways in cold climates have that concern to worry about. Yet once concrete gets its strength, it doesn’t freeze.

Can Concrete Freeze And What Happens If It Does?

There is the setting period that you have to worry about. That’s what it’s all about when it comes to the concrete gaining its strength. The setting period for concrete is the 14 to 28 day period. Now, let’s say that you pour concrete in an area when the temperature is 50 degrees. It is going to set more slowly, not gaining strength as quickly. When the temperature is over 50 degrees, it should set like normal. Click here to get more information.

But let’s say that the temperature is 40 degrees or below. First, if you get too close to 30 degrees, you’re going to be in freezing temperatures anyway, which means that the concrete could definitely freeze. But even at 40, which isn’t freezing weather, the cold temperature is going to keep the concrete from gaining strength at all.

Can Concrete Freeze And What Happens If It Does?

Colder temperatures can in fact slow down the setting period for the concrete, causing there to be more of a window of time for the concrete to freeze and endure other issues. And you can see that there doesn’t have to be freezing weather for the setting of the concrete to slow down. It’s just how things work.

Ideally, the concrete would be poured when there isn’t a window of 50 degree weather anytime soon. That would mean that it would properly set in the regular timeframe, 14 to 28 days. If you can get the job done during the summer, perhaps that’s a good option.

Some areas have less cold weather than others. In parts of the country where winters are harsh, there isn’t going to be any concrete pouring going on during the season. Yet that means business will be booming during the warmer months.

Now you know what to expect when it comes to concrete and whether or not it can freeze. It sure can, but the thing about it is that once it is strong enough, it’s not going to freeze. It will be strong enough to where the weather doesn’t affect it at all. If there are colder temperatures just around the corner, you might want to go ahead and wait on that project until a more ideal time, just in case. Of course, there are also heaters that can be used in cold concrete construction.
