The purpose of this study is to investigate certain features of a novel material proposed to serve as an impervious liner in sanitary landfills. Various ratios of bentonites and zeolites (B/Z) compacted at optimum water content were tested to determine the strength parameters, permeability, pH, heavy metals and other properties. A B/Z ratio of 0.10 was found to be an ideal landfill liner material regarding its low hydraulic conductivity and high CEC. The use of B/Z mixtures as an alternative to clay liners would significantly reduce the thickness of base liner for sanitary landfills.
