Abstract: A ground thawing mat includes at least a flexible upper sheet overlaying a serpentine twinned array of flexible heating fluid conduits, wherein the twinned array include at least a closely adjacent and parallel pair of conduits extending from a heating fluid inlet entering the parallel pairs of conduits to a heating fluid outlet exiting the parallel pair of conduits, and wherein the parallel pair of conduits extend substantially linearly without crossing one another between opposed serpentine turns. Further, the parallel pair of conduits turn through the turns without crossing one another so that the twinned array lie substantially in a single plane overlaid by the upper sheet.
