Ground thawing in the arctic has its own unique challenges. Tundra ground has rather moist soil and air temperatures reach as low as 56° F, with wind chills approaching 100° F. Some areas of the arctic have frost depths of more than 2000 feet. Needless to say, work in this environment is quite extreme.
The solution is the Ground Heater E3000 model. Unlike steam thawing which can further saturate soil making a muddy slop mess, the Ground Heater drives down moisture and heat deep into the soil.
The Ground Heater can thaw up to a depth of 6 feet in around 115 hours depending on soil contents.
