Description

Powerblanket’s 3×4 ground thawing heated blanket provides a highly effective solution for thawing frozen ground, keeping vehicle or equipment engines warm, and melting dangerous ice dams. Unlike typical concrete curing blankets, these ground thaw blankets not only offer a higher watt density but also deliver more uniform heat distribution, which helps prevent hot and cold spots.

These ground-thawing blankets are specifically designed to reduce downtime and eliminate the hassle of dealing with frozen ground during winter. They heat up to a preset of 150°F ± 10°F (65°C ± 5°C), quickly melting snow and ice from roofs, walkways, and construction areas. When paired with a thermostatic controller, they offer even greater heat control for a variety of applications.

3’x4’ ground thawing heated blankets come in two different thermal rating classes: 

  • Powerblanket: Designed for standard heating applications, this model features a rugged vinyl shell and safely raises material temperatures as high as 145°F. It can operate in temperatures as low as -20°F.
  • Powerblanket Xtreme: Built for harsh climates, this version also includes a rugged vinyl shell and safely raises material temperatures up to 145°F, functioning effectively in temperatures as low as -50°F.

Additionally, all of our ground thawing blankets come with an insulated, water-resistant design for durability and reliability. Every Powerblanket product is ETL-certified to meet UL, CSA, and CE safety standards, ensuring both safety and performance.

    Used it for ground thawing
    Amazing product, Works exceptionally well. Thawed frozen ground at a rate of 3ft in 24 hours. Also used as a engine heater.

  2. –

    These really do a great job of thawing ground quickly
    These really do a great job of thawing ground quickly. I live in North Dakota and the frost can get to 8′ in some harsh winters, even some rural water lines froze a couple years back. These will usually thaw about a foot a day directly below the blanket and it’s surprising how easy it digs with the moisture softening up the soil. As an electrician these have been a real life saver.

    Reliable
    What I like most is that it worked. Reliable. What I like least would be great if it had a storage case.

  4. –

    good product and works as intended
    I used it last season as an engine warmer for a car that lacked a block heater and it worked well for that purpose even when the temperatures fell below -20 degrees. For that purpose, it fully covered the top part of the engine compartment and also worked to keep the battery warm. I will be adding an external oil pan heater to that vehicle next season, but I will still use this blanket. I also used it to remove some ice buildup on my deck, and it melted through it in a day and half. All in all, good product and works as intended.

    Perfect size for posts poles

    It works well in a tough application
    I am very satisfied with this product. I have an ongoing problem with melting snow dripping from my carport metal roof that re-freezes the minute the sun goes down. Consequently a lump of solid ice builds up and won’t budge even with a matock. Yesterday afternoon laid the powerblanket on part of it. The overnight temp was 15F. This morning it was completely melted! Those who say it doesn’t work are either laying it out upside down, or may have a defective unit. 5 stars so far -I hope it lasts for a few years.

    Good thawing blanket for frozen ground
    I used it two times this winter to thaw frozen ground in Central Wisconsin. It did the job quite well. 5/30/20. Used it again this winter. It is still working very well.

    Works Great!!!
    I like the fact it was so easy to use. I am a 75 year old woman, and it is easy for me to pick up and lie down on my porch to melt snow.

  10. –

    Perfect for cold winters!
    The first one we received did not work properly. However, after returning it and receiving the new one we love it! Works great on ice!

    The best on the market by far
    Everything works great! I am a contractor and had to dig an egress in winter time. This blacket thawed 36″ down in about 78 hours! Minimal cost on electric bill! Would 100% recommend

Why Choose Powerblanket Ground Thawing & Curing Blankets?

Key Benefits of the 3×4 Ground Thawing Heated Blanket for Winter Projects

  • Heats quickly to a preset 150°F, perfect for thawing ground and melting ice.
  • High-watt density thaws frozen ground faster than conventional methods.
  • Reduces cold weather-related delays on construction sites.
  • Ground thaw blankets eliminate frost and are ideal for prepping surfaces for concrete pours.
  • Safe and easy to use in extreme cold, with outdoor heat blankets designed for durability.
  • Provides uniform heat distribution, ensuring no damage to surfaces or materials.

Curing Epoxy Resins

Curing epoxy resins with Powerblanket curing blankets is easy and efficient! Most epoxy resin and hardener combinations require heat in order to cure since ambient temperatures are not high enough. If the epoxy resins are not heated high enough and evenly enough, the chemical, mechanical, and heat resistance properties become compromised. In fact, some epoxy resins require heating in steps to prevent overheating from exothermic reactions.

Here's How Powerblanket Can Make Your Epoxy Curing Process Easier:

Ensure Consistent Results with Powerblanket’s Advanced Heating Technology

  • Powerblanket Curing Blankets maintain optimal temperatures for resins throughout the curing process.
  • Molds are preheated efficiently with Powerblanket Curing Blankets before application.
  • Epoxy cures evenly with Powerblanket’s heat-spreading technology.
  • Critical materials are heated safely with Powerblanket, ensuring no damage or compromise.

Hear What One of Our Loyal Customers Had To Say

“Powerblanket Extra Hot Curing Blankets have simplified the post-curing process for our composite parts. Quick and easy to use on a variety of different shaped parts. The Powerblanket heaters have significantly decreased our setup time and operating costs, saving us several thousand dollars on our current carbon-fiber project. The Powerblanket team was responsive, and the blankets shipped quickly. I’m very glad we came across the amazing new technology.”- Richard A. Difede
