The state-of-the-art for barriers systems control of pollution migration and hydraulic
structures including liner systems for landfills, mine waste, and dams/lagoons are discussed …

Smectite-based geosynthetic clay liners (GCLs) are popularly employed as hydraulic
barriers due to their low permeability and high swelling capacity. The exposure of GCLs to …

The purpose of hydraulic barriers, such as geosynthetic clay liners (GCLs), is to isolate
waste liquids from the environment. Bentonite clay is widely used in GCLs because of its …

Waste disposal facilities are often isolated by clay liners in order to prevent pollutant
migration into the ground. Bentonite is used as barrier material thanks to the low conductivity …

Dense prehydrated geosynthetic clay liners (DPH-GCLs) are a particular type of GCL which,
unlike conventional GCLs manufactured with dry bentonite, contain bentonite prehydrated …

Amended bentonites have been proposed with the primary purpose of improving their
chemical compatibility relative to conventional bentonite. As these materials are relatively …

The aim of this Specialized Lecture is to present the recent advances and issues, as well as
original research, on Modified Clays for Barriers. Topics of interest include:(1) long-term …

Geosynthetic clay liners (GCLs) are used in landfill applications because of their high
deformation resistance and excellent self-healing ability. In the present study, air and …

Geosynthetic clay liners (GCLs) are mostly used as flow barriers in landfills and waste
containments due to their low hydraulic conductivity to prevent the leachate from reaching …

Exposure to liquids with high electrolyte concentrations or high cation valence present in
landfill leachates can cause significant increases in hydraulic conductivity of clays due to a …
