This study presents an investigation into the possibility of using sepiolite and zeolite mixtures to design a landfill liner. Leakage from the impervious layer into the environment is the main difficulty of storing hazardous waste. Therefore, determining the impermeable layer and in-situ application procedure is very important and needs laboratory experimentation. For this purpose, a series of experiments have been conducted on a mixture of zeolite+sepiolite. The geotechnical, physico-chemical and micro-structural properties of 30% sepiolite by weight of zeolite have been determined through laboratory testing. At the end of the research, the results show that zeolitesepiolite mixtures can be effectively used in bottom lining systems for hazardous, industrial and municipal waste.
