Abstract

The design and maintenance of landfills for waste disposal has received great attention over the last few decades due to the increasing interest and attention paid to environment protection issues, such as ground and ground water protection. Over the years, landfill liner construction has seen innovative new practices such as addition of engineered clays, synthetic lining material and designing of more sophisticated leachate collection systems. The main objective of such practices is to enhance the landfill liner performance as a hydraulic barrier and to minimise or prevent the migration of landfill leachate into the surrounding hydro-geological system. The compacted clay liners (CCLs) are among the most widely used hydraulic barrier system in modern waste containment systems.
