This paper is made to showcase and review the various researches which have been done on landfill liner materials. A variety of materials have been tested and experimented for its usefulness as a landfill liner material by many researches. The use of compacted clay liners was started three decades ago. Some geosynthetic materials like geomembranes were also introduced in due course of time since it shows better performance in the matter of less permeability and better crack resistance. But what makes the researchers to continue finding more suitable materials is that in exploring a material which fulfils all the standard requirements and at the same timecost effective. In recent years many researchers are working on paper pulp sludge, straw fibres and bagasse ash and found them veryimpressive in their performances as good liner materials. Bentonite, despite being one of the best soils useful in liner construction, is little bit expensive. But when used in small proportions with commonly available soils like laterite can replace most of all the conventional clay liners. Pozzolanic soils like metakaolin have marked their place as an important alternative when used along with the conventional liner systems in strongly resisting the penetration of rainwater and leachates and preventing them from entering the groundwater. © 2017 IAEME Publication.
