ABSTRACT:
A method and apparatus are provided for remediation of near surface soils, pavements and other surfaces using a radiant heating plate, an insulating layer, and a vapor barrier above the radiant heating plate and below the insulation. The radiant heating plate transfers thermal energy to the surface primarily by radiation and therefore need not be in contact with the surface over large areas. The radiant heating plate may also serve as a vacuum barrier for collecting contaminant vapors emanating from the subsurface soil.
