Though cold weather is not typically too much of a problem in a couple of areas in the United States, most of them do get the infrequent freeze. You must be ready whenever a freeze happens if you are planning a concrete project during the winter.
Here are a couple of things that you have to think about if you want to pour concrete in winter for your concrete patio.
Protect the Concrete Once It is Troweled
You have to protect the concrete from the cold after it is smooth and has been troweled. To keep the slab warm, you can add a tarp and insulating blankets. You’ve got to ensure you add weighted objects such as wood on top. This will help hold down the tarp.
Think About the Amount of Time the Concrete Sits in the Chute
If concrete sits in the chute for a longer period in freezing weather, it will freeze. You shouldn’t leave concrete in the chute for longer than 5 minutes. You’ve got to work as fast as you can.
Think About the Weather During the Day of the Estimated Timeline of the Job
The temperature should ideally be at least 28°F outdoors. Fresh concrete will freeze if the air temperature drops below 25 degrees. The temperature should be between 65°F and 70°F whenever concrete is poured as long as it has been mixed using hot water. Also, if you want to plan around this issue, you’ve got to monitor the weather forecast.
Think About Whether the Sub-base is Frozen
You need to wait always if the ground is still freezing. Before you pour concrete, you have to wait until it’s thawed. The concrete will crack after the ground thaws if you pour over frost. You can utilize ground heaters to thaw the ground if you want to speed up this process.
Think About the Sub-Base that You Are Pouring On
A cold sub-base will quickly suck the heat out of the concrete if you are directly pouring onto a plastic vapor or dirt barrier on top of the ground. That is why you should not pour if the temperatures are lower than 26°F.
To keep warm, wearing layers is the most effective method when working in the cold. As the temperatures begin to increase, you can always remove your layers. If you want to protect your head and ears, you can always wear a hoodie. An excellent way to protect your feet is to wear thick wool socks together with rubber boots.
Have a Temporary On-site Heat
You can immediately warm up your feet and hands if you bring a temporary heater outside. With this, you won’t have to run inside a lot of times just to warm yourself up. You can prevent frostbite if you keep your hands warm. Also, you can guarantee that your accurate movements aren’t affected by stiff and numb hands.
