Abstract: ABSTRACT In landfill design, the containment of solid and liquid contaminants is essential. Leachate is produced from the liquid squeezed out of the waste itself (primary leachate) and by water that infiltrates into the landfill and that percolates through the waste (secondary leachate). This liquid can become a health hazard if it enters the groundwater system. Liners are placed beneath leachate collection systems to avoid leachate from seeping into the soil underneath the landfill. Geosynthetic clay liners (GCLs), usually containing bentonite clay, are widely used as bottom liners and final covers for landfills. However, currently used GCLs suffer problems of slope stability, lower shear strength, lower puncture resistance, high long‐term diffusive flux, and lower leachate attenuation capacity due to lower thickness of the Geosynthetic Clay Liner. In this study, the modification of geosynthetic clay liner is done using various Geosynthetic materials to reduce the disadvantages of the existing Geosynthetic Clay Liner. The materials used to make the internal structure of the geosynthetic clay liner are flexible pipes, non‐woven geotextile, geonet, and geogrid.
