Recent development of treated clays for geosynthetic clay liners and barriers systems

Abstract
Geosynthetic Clay Liners (GCLs) are largely used for the isolation of pollutants because of their particularly low hydraulic conductivity to water. However, prolonged exposure of the clay to polluted liquids can drastically increase their hydraulic conductivity, with a consequent enormous damage to the environment. To overcome this problem, modified clays have been recently introduced in barrier applications to improve their chemical resistance to aggressive permeants. Some examples are: Organoclays, MSB, Trisoplast, HY-PER clay, DPH GCL, SW101, BPN. In view of pollutant containment applications, it is of great interest to evaluate the potential benefits of these treated clays, their transport parameters, and to evaluate the treatment techniques more suitable to preserve the sealing performance in the long term. This paper provides an overview of recent advancement in this field.
