Abstract
This invention relates to a method for insulating sub-soil comprising mechanically destructuring the sub-soil, injecting an insulating material into the destructured sub-soil, and mixing the sub-soil and the insulating material. The thermal conductivity of the insulating material is strictly lower than the thermal conductivity of the sub-soil.
