RESISTEX® Geosynthetic Clay Liners

 

Meeting the Most Demanding Chemical Compatibility Requirements

RESISTEX Geosynthetic Clay Liners are a polymer-modified bentonite GCL that are engineered to provide the highest level of chemical compatibility for hydraulic barrier performance in extremely aggressive leachate environments. 

 

Our RESISTEX family of GCLs offer compatibility with a wide range of pH, electrical conductivity, and ionic strengths that are common to mining liquids. CETCO recommends project-specific compatibility testing for the proper selection from the RESISTEX family of GCLs.

 

Unmatched chemical resistance

Dry-blended, polymer-treated GCLs are designed to provide improved chemical resistance in moderately aggressive leachate environments. The polymers help to reduce the effects of cation exchange by swelling and partly offsetting the reduced bentonite swell.

 

RESISTEX GCLs offer compatibility with a wide range of pH, electrical conductivity, and ionic strengths and are more effective than standard bentonite for contaminated chemical environments. RESISTEX GCLs may be custom engineered to meet project-specific requirements and are available with different polymer types and loadings.
