RESISTEX® Geosynthetic Clay Liners

Meeting the most demanding chemical compatibility requirements


2015 GeoMe award winner for "Best Geosynthetics Innovation and Technology", RESISTEX® Geosynthetic Clay Liner is a polymer-modified bentonite GCL that is 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.


Applications include: bauxite residual storage; evaporation/retention basins; leach pads; capping.
