This paper also compares geosynthetic clay liner and compacted clay liner based on certain criteria such as thickness, availability of materials, vulnerability to damage etc.

This paper summaries the important geotechnical characteristics such as hydraulic conductivity, liquid limit and free swell index of geosynthetic clay liner and compacted clay liner based on research findings. Because of low permeability geosynthetic clay liners and compacted clay liners are the main materials used in waste disposal landfills. Liners and covers for municipal and hazardous waste containment facilities are often constructed with the use of fine-grained, low plasticity soils. Earthen liners have been widely used to contain waste materials in landfill. Liner in a landfill is an important component which prevent leachate migration and prevent groundwater contamination. The most common problems of the landfill site are environmental degradation and groundwater contamination caused by leachate produced during the decomposition process of organic material and rainfall. One of the common methods of disposal is landfilling.
However many wastes that cannot be used beneficially must be disposed of ensuring environmental safety. Human activity inevitably produces waste materials that must be managed. Comprehensive review of geosynthetic clay liner and compacted clay liner
