CUSTOM FLAT BLANKETS
Powerblanket custom flat blankets offer a manageable and realistic method for curing concrete and thawing frozen ground in cold and adverse weather conditions. Cold weather can seriously slow down concrete cure time and significantly hold up construction projects. A new concrete pour must maintain a temperature above 50 °F for approximately 48 hours for the necessary chemical reactions to take place to achieve ideal concreting strength. If your livelihood involves working outside, you understand that prep often takes longer than the actual job. Powerblanket has considered the difficulties and delays associated with cold and freezing temperatures and has created a solution.
When your job exceeds the limits of what a standard Powerblanket can do, Powerblanket’s world-class engineers will create a custom flat blanket solution for you.Download Custom Brochure

CUSTOM COLD WEATHER CONCRETE INNOVATIONS
Water in concrete can freeze starting at 30°F (-1°C) and at around 27°F (-3°C) the hydration process can stop entirely. Since ice occupies about 9 percent more space than water, this can seriously affect the integrity of the concrete. Massman Construction Company concluded that the traditional solution of erecting a structure and heating up the ambient air temperature wouldn’t work on an important Kansas City bridge project. They turned to Powerblanket heated curing blankets, which warmed up the surrounding concrete and support beam, and then kept a constant temperature on the concrete. This innovative solution finished the job.
Cold Weather Concreting 50°F is the Magic Number
Experts agree that the best temperature for pouring concrete is between 50-60 °F. Necessary chemical reactions that set and strengthen concrete slow significantly below 50 °F and are almost non-existent below 40 °F. Even when daytime temperatures are within the satisfactory range, winter concrete setting creates risks that could result in weak, inadequate concrete. If nighttime temperatures are below freezing, the water in the concrete will freeze and expand and crack the finished product. With Powerblanket, concrete can still be successfully placed during even the coldest months of the year.
