Abstract

A low-permeability barrier for waste disposal sites such as landfills and waste lagoons, and a method for constructing the same, includes a waste material. The waste material is stabilized to decrease the permeability characteristics of the waste material and may be further processed to improve the structural characteristics of the waste material and to prevent leaching of any leachable components. A method is provided for applying the waste material to the waste disposal site as a liner, interim cover, and/or final cover.
