This study is to evaluate a charge of the physical properties of the landfill liner system under the unique domestic climatic condition of winter in Korea, i.e, 3 days harsh and 4 days mild climate. The two wats to estimate the climatic influence to the liner system were performed ; namely, permeability and uniaxial compression test. The samples used in this test were the mixture of the WGS (Weathered Granitic Soil) and MCG (Mullite Carbon Gypsum). Mixing ratio was in a weight basis of 95 : 5 , 90 : 10 , 85 : 15 , and 80 : 20, respectively. The compressive strength of the sample was mostly increased from 36% to 112% after freeze and thaw cycles. Moisture supply during freeze and thaw cycles gave an increase of the compressive strength of the sample, while the permeability was decreased. The results showed that the addition of MCG to the WGS could prevent the increase of permeability triggered by the MCG and WGS. The hydration products of MCG and WGS plugged the pores which once were filled by water.
