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 sensitivity of sodium bentonite (Na-B) to adverse chemical interactions has spurred
development of enhanced bentonites (EBs) for geosynthetic clay liners (GCLs) that provide …

The performance of clay liners may be impaired when in contact with aggressive solutions
due to cation exchange. The efficiency of these liners can further deteriorate if cation …

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 …

Chemically modified bentonites are being developed with the aim of preserving low
hydraulic conductivity in the presence of potentially aggressive permeants in pollutant …

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

The possible substitution of chemically modified bentonites (CMBs) for traditional (non-
treated or unmodified) sodium bentonites (Na-bentonites) has gained momentum due to the …

Geosynthetic clay liners (GCLs) are widely used as hydraulic barrier to isolate waste
disposal facilities thanks to their low permeability to water. In the field, the efficiency of GCLs …

Geosynthetic clay liners (GCLs) are widely used to isolate waste disposal facilities in order
to prevent pollutant migration into the ground. GCLs are factory-manufactured hydraulic …

The present invention relates to improved clayey barriers, such as compacted clay liners or
geosynthetic clay liners, which can be used, among other uses, to isolate waste liquids from …
