Pouring concrete in winter months can present unique challenges due to the colder temperatures. However, it’s not impossible with proper planning and precautions.
We’ve had an exceptionally busy winter despite the decreasing temperatures. A great example of a cold weather concrete pour was Human Bean, a new coffee shop located in North Georgia.
The overnight temperature was well below freezing in the upper 20s but with the promise of rising temperature throughout the day, we were able to proceed with the project as scheduled.
While pouring concrete in winter, we use the following process as we schedule projects for our clients to ensure that the concrete cures properly.
- Temperature Consideration:
We check the weather forecast: We aim to pour concrete on days when the temperature remains above freezing for a sustained period. Extreme cold can adversely affect the curing process.
We use concrete blankets or heated enclosures: Covering the area with insulated blankets or using heated enclosures can help maintain the necessary temperature for proper curing.
- Concrete Mix Adjustments:
We use accelerators: Additives like calcium chloride or non-chloride accelerators can speed up the curing process in colder temperatures.
We also adjust the concrete mix: A mix with a lower water content can help prevent freezing and ensure proper strength development.
- Site Preparation:
Heating the ground: If possible, we heat the ground where the concrete will be poured to prevent freezing.
Use insulated forms: The use of Insulated forms can help retain heat within the concrete as it sets.
- Timing and Working Conditions:
We plan the pour during the warmest part of the day: Mid-morning to early afternoon is often the best time during colder months.
We protect our workers: We ensure that workers have appropriate clothing and heating sources nearby to prevent cold-related injuries.
- Curing and Protection:
Cover the concrete: We immediately cover the poured concrete with insulating blankets or straw to retain heat and moisture when necessary.
Avoid rapid temperature changes: Sudden temperature drops can negatively impact the curing process. We pour when maintaining a consistent temperature during curing is feasible.
- Monitor the Concrete:
We also regularly check the temperature of the concrete using thermometers, ensuring it remains within the specified range for proper curing.
- Patience and Additional Care:
We understand that curing might take longer: Concrete poured in colder temperatures may require extended curing times. Patience and allowing ample time for proper setting and strength development is our key to a successful pour.
Safety Note: If you are a DIYer, always follow safety guidelines and consult with concrete professionals or contractors experienced in pouring concrete in cold weather. They can provide valuable insights and recommendations based on specific conditions and local climate.
Remember, while pouring concrete during colder weather is feasible, it requires extra attention and precautions to ensure a successful outcome. When done correctly, you can achieve durable and strong concrete even in winter conditions.
