As the seasons change and temperatures drop, concrete season typically begins to wrap up until warmer weather returns. While there are four seasons in the Chicagoland area, there are areas around the world that experience colder temperatures longer, such as Alaska, who may not have the option to wait for warmer temperatures to pour concrete, therefore concrete blankest are critical.

When temperatures drop below 40 degrees Fahrenheit concrete blankets are necessary to avoid the concrete mixture from freezing and causing damage. While curing, concrete warms up from the inside, therefore the blankets help to trap that heat, thus blocking the colder temperatures from jeopardizing the freshly poured concrete.

Concrete blankets are just as they sound, insulated blankets used to warm curing concrete. As you would use a blanket to warm the exterior surface of the body keeping the cold away, these blankets offer the freshly poured surface the same benefit.

Used to construct the foundations of a garage or home to sidewalks and basketball hoop anchors; concrete is a widely popular material with a wide range of possibilities. To cure and strengthen properly, it may be necessary to take additional steps to prevent damaging the product.

What does It Mean To Cure?

Curing is the process concrete takes to strengthen after being poured. The first 24 hours of the curing process are crucial; therefore, it is important to be prepared for all circumstances that could potentially hinder this step. Much as it is advised to not pour in the rain, or with it in the immediate forecast, it is wise to be knowledgeable of the evening and overnight temperatures.

Made 15-20% of water, concrete can be destroyed in the early curing stages if the water is unprotected and freezes. The internal structure of the concrete won’t form properly, and these bonds can break down due to freezing.  This can lead to the concrete becoming damaged– leaving it flaking on the surface with internal weak spots.

While some additional water may not affect the mixture and end-results, too much water can result in the compromising of the integrity of the structure. Moisture is necessary during the curing process. On dryer, warmer days, misting the concrete to prevent cracking is advised. Concrete blankets trap additional moisture, allowing for the surface to receive the necessary moisture to prevent that cracking.

How Are Concrete Blankets Used?

Again, as soon as temperatures begin to drop below 40 degrees in the evening, blankets are advised. Ideally, concrete is always poured on warm sunny days when the weather elements will not affect the result. Reality is that weather is unpredictable, but it can be worked around.

One layer of insulated blankets can cover the entire surface of the area, trapping the heat during those crucial first few hours

Taking the time to ensure that the blankets are flat, seams are covered, and the entire surface blankets will help to prevent the concrete from breaking down.

While they are large, they can be folded back up when no longer needed and easily reused. Their durability and weatherproof nature make them a wise investment for those with reoccurring concrete projects year-round.
