A method of reducing ground disturbance during freeze-thaw cycles. The steps include excavating soil from an area affected by ground disturbance due to subsurface flow and subsequent freezing of water. A subsurface layer of thermal insulation is then laid over the affected area, thereby thermally insulating the affected area from freezing. The subsurface layer of thermal insulation has a top surface and a bottom surface . A subsurface layer of wick material capable of drawing water away from the affected area by capillary action is also laid parallel to one of the top surface or the bottom surface of the subsurface layer of thermal insulation positioned in a path of the subsurface flow of water.
