Covering Concrete is our Business
Therma-Crete blankets use patent-pending technology to protect freshly poured concrete from the harmful effects of the weather.
Why Winter Is Not Optimal for Pouring Concrete
Concrete that gets cold too quickly will weaken, which is not a good start to any concrete project. If you follow certain precautions, you may be able to successfully pour your concrete.
Because pouring concrete in the winter is problematic enough, it really isn't a DIY homeowner project and should be performed by a professional. Your professional will first have to ensure that the ground upon which he's pouring concrete is not frozen.
Concrete is a mixture of water, Portland cement, and an aggregate. As the concrete hardens a chemical reaction occurs in which the water crystals expand between the sand and gravel and bind them together. This process requires a particular temperature range to harden and cure, which if not met, will interfere with its integrity. If the water crystals freeze it can cause cracks and spauling in the hardened concrete.
How Does it work?
The curing process is essential to strong, long-lasting concrete. Therma-Crete Blankets help concrete to cure properly by protecting it from rain, snow, ice, and extreme temperatures.
During the winter, with the blue side facing up, the heat from the sun is absorbed and through convention it transfers down to the concrete.
During the summer, the blanket can be placed with the foil side facing up, making the Toppertmtransfers excess heat away from the concrete. A tough cross woven polyethylene shell on both sides allows the Toppertmto keep precipitation and unwanted debris away from the pour no matter what season.
Using Therma-Crete Successfully in the Winter
The ingredients used in the concrete mix will likely be heated, and a faster curing cement used. Once the cement is poured, a liquid curing compound can be sprayed on the surface and an insulated blanket placed over the concrete.
Because our Curing Blankets come in a roll, labourers simply push the roll out on the slab where it laid flat. As the slabs cured, the wind removed about a third to half of the synthetic blankets, even though those blankets had been weighted but not taped. The pulp blanket, not weighted down or taped, remained completely in place. We attribute this to the pulp blanket's absorbed water weight.

Concrete curing blankets are easy to use and maintain and don’t create environmental hazards: no noxious fumes, no open flames, and no toxic emissions.
, agricultural, landscaping, or construction settings.
Curing blankets can also keep the ground from freezing, protecting from the effects of freezing weather, snow, or ice. Concrete curing blankets can also be used to protect newly-poured concrete, brick, or stone walkways and paths, ensuring optimal curing temperatures and a long-lasting, durable product.
pour concrete on frozen ground. Plan your work and work your plan. You can effectively keep your team working all winter long with a good curing blanket.
Our concrete curing blankets are designed for both hot and cold weather, adding reflective technology to the curing process. This allows the concrete to maintain sufficient levels of water and heat so that the concrete can achieve it’s desired physical properties. Constructed from laminated layers of tough woven polypropylene, aluminum, and foam insulation material.
• Allows concreting operations in low ambient temperature conditions.
• Allows earlier release of pre-stress.
• Reduced time to impose loading.
• Allows more precise project scheduling, as concrete pours are more likely to take place.
• Reduced project stoppages and overall completion time.
• Simple storage; re-usable.
• Elimination of temporary enclosures.
• Improved health & safety on site, through elimination of naked flame burners.
• No risk of carbonation to concrete - a consequence of using open flame burners.
