How warm do concrete blankets keep concrete?
Not only do concrete blankets help maintain a temperature above 40 degrees, but they also lock in moisture. Moisture is a very important part of the curing process. It’s needed to prevent cracks and rapid drying. Working with concrete in extremely hot and dry weather is just as challenging as in the cold.
What is an insulated concrete blanket?
Our concrete blankets are manufactured for construction sites for keeping the curing process at the right temperature during cold weather and frost. These insulated curing blankets are easily transported and installed and maintain ACI compliance for cold-weather concreting.
What is the R value of a concrete blanket?
These Concrete Curing Blankets have high quality 6 mil Poly skins that create an R-Value of 5.11. This durable skin is a woven with reinforced poly that has a Black top surface and Silver bottom. The blankets have a closed cell foam, bubble and a reflective layer that provides insulation between the poly skins.
Can you use a tarp as a concrete blanket?
The insulated tarps are used most often for concrete curing as they are laid over freshly poured concrete so that it can cure in cold weather. Heating concrete curing blankets also known as heated concrete tarps are used in the same method as the insulated construction covers.
How long should you leave concrete blankets on for?
Use insulation blankets or heated enclosures to maintain concrete temperatures above 50° degrees Fahrenheit for three to seven days. Use a good quality curing compound if you are unable to maintain concrete temperatures above 50° degrees Fahrenheit for three to seven days.
Will concrete blankets thaw the ground?
Thawing the ground for landscaping Cold weather can cause the ground on your construction site to freeze over, making landscaping projects incredibly difficult. Fortunately, you can apply concrete blankets over frozen ground to quickly thaw it out.
When should you use concrete blankets?
For flatwork, the traditional, and still the best way, to protect concrete from the cold is to cover it with blankets after it’s been finished. Since the ground is a bit warmer and the concrete generates its own heat, blankets will keep it warm even if the temperature goes below 20°F.
How long does concrete need to cure before freezing?
At specified curing temperatures, well-portioned concrete mixtures should attain this strength within 24 to 48 hours. Therefore, it is critical that newly placed concrete be protected from freezing for the first 24 to 48 hours or until the concrete attains a strength of approximately 500 psi.
What is the R value of a tarp?
Due to the weight and layering of this material, we generally can’t make insulated tarps that are larger than about 1,000 square feet. These tarps have never been tested to establish an accurate R-value but they are estimated to have an R-value of 3 or 4.
Can you pour concrete when it’s below freezing?
Experts agree—the best temperature to pour concrete is between 40° – 60°F. When temperatures dip below 40°F, the chemical reactions that strengthen concrete slow down and can lead to weaker concrete.
How long do you need to keep concrete blankets on?
How cold do concrete blankets work?
Concrete blankets are incredibly effective at keeping the material warm during its curing process. In fact, these blankets can keep concrete at an ideal temperature even when the weather drops below 20°F. And since the setting process occurs so quickly, you’ll usually only need to rent one out for a couple of days.
Why Insulated Concrete blankets?
Insulated Concrete Curing Blankets Our concrete blankets are manufactured for construction sites for keeping the curing process at the right temperature during cold weather and frost. These insulated curing blankets are easily transported and installed and maintain ACI compliance for cold-weather concreting.

What is a concrete curing blanket?
These concrete curing blankets feature a deep black on the exterior to provide maximum temperature gain from solar heat and to help the interior insulation layers maximize R values; they’re silver on the bottom. Our concrete curing blankets are available in a range of different R values up to 7.7.
What is the best insulation for concrete work?
Using the toughest woven polyethylene fabric for correct insulation and extended longevity, Tarps Now manufactures all its concrete curing blankets in the U.S. with flexible foam that provides the highest possible R value. That translates into the best possible insulation for concrete work on the job site.
