This paper investigates the potential use of Kuttanad soil with waste from KMML (Kerala Minerals and Metals Ltd.) as a landfill liner. The variation in the liquid limit, maximum dry density and optimum moisture content, unconfined compressive strength and permeability by the addition of 0%, 5%, 10%, 15%, 20% and 25% of waste from KMML to the Kuttanad soil is studied. The addition of the waste from KMML reduces the liquid limit and plasticity index of the Kuttanad soil, the maximum dry density was increased by the addition of waste up to 20% of waste and then the maximum dry density decreased. Optimum moisture content shows the opposite trend of maximum dry density that is the optimum moisture content was decreased with increase in dry density. The UC strength shows an increasing trend up to 20% addition of waste and then it decreased. By conducting FESEM analysis the soil structure is found to be flocculated at the 20% (optimum) addition of waste from KMML. The permeability value was found to be decreasing by the addition of the waste from KMML satisfying the condition required for the landfill liner material.
