The object of the present invention to provide a method for thawing frozen ground for laying concrete primarily at a construction site by use of a continuous length of circulating hose placed on the frozen ground inside and/or adjacent a concrete form where the concrete will be laid, covering the circulating hose with a layer of aggregate material for insulation from cold air leaving the ends of the circulating hose protruding from the aggregate connecting the ends of the hose to a source of heated liquid to circulate warm liquid through the circulating hose to thaw the frozen ground, laying the concrete in the concrete form while continuing to circulate heated liquid in the circulating hose to prevent the concrete from freezing, leaving the portion of the hose in the form under the concrete by cutting the ends protruding from the aggregate, removing the remaining portions of the hose.
