Over the past decade, geosynthetic clay liners (GCLs) have gained widespread popularity
as a substitute for compacted clay liners in cover systems and composite bottom liners. They …

The objective of the paper is to give an update in key topics related to performance issues of
barrier systems for landfills. The objective of using barrier systems is to minimize the impact …

This lecture describes the latest findings with respect to the long-term performance of
modern municipal solid waste (MSW) landfill barrier systems. Field data relating to the …

The protection of groundwater and surface water from contamination by the escape of
contaminant from waste disposal is now an important consideration in many countries of the …

Fundamental factors and testing considerations affecting the evaluation of the hydraulic
conductivity of geosynthetic clay liners (GCLs) permeated with non-standard liquids (ie …

The factors that may affect short-term leakage through composite liners are examined. It is
shown that the leakage through composite liners is only a very small fraction of that …

The behaviour of geosynthetic clay liners (GCLs) as part of a physical-environmental system
is examined. Consideration is given to:(a) both the physical and hydraulic interactions with …

The results of long-term hydraulic conductivity test results on two modified bentonite
materials, a multiswellable bentonite (MSB) and a dense-prehydrated geosynthetic clay liner …

Abstract Design-and construction-related factors that affect leakage through geomembranes,
used either alone or in a composite liner, are examined. The development, detection, and …

This paper summarizes the basic concepts and mechanisms related to the durability of
HDPE geomembranes and discusses the factors influencing the service life of …
