The purpose of this study is to form the impermeable layer as landfill liner to store boron mine waste water. Boron mine waste water was supplied from Emet (district of Kutahya city, Turkey) Boron Factory. In this study, five different mixtures were used. These mixtures were natural soil, natural soil mixed with Na-bentonite (10%, 20%, 30% and 40%). A miniature landfill tank (240 cm × 120 cm × 60 cm) with six sections was constructed and mixtures were compacted in the container according to the optimum water content. After curing period, 120 liter boron mine waste water was poured into each section and impermeability of mixtures was observed. As a result of observations, it was seen that natural soil was totally inefficient material. Natural soil started leaking on the fifth day and waste water was completely leaked within 27 days. Natural soil mixed Na-bentonite (40%) mixture gave the best result among them. The thickness of impermeable layer formed with natural soil mixed Na-bentonite (40%) can be offered between 40 and 60 cm for the in-situ application.
