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.
RESISTEX Geosynthetic Clay Liners were the recipient of the GeoME "Best Geosynthetics and Technology" award in 2015.
Common applications for RESISTEX GCLs
We build all of our GCLs to be compliant with GRI-GCL3 and their guide specifications can be found for use on the Geosynthetic Institute website.
