In this paper, the hydration of geosynthetic clay liners (GCL) from underlying subsoils is described. GCL specimens with difference in the type and connection of geotextiles were placed in contact with subsoils that vary in soil grain size distribution and initial moisture contents under simulated field conditions. The rate and degree of hydration of GCLs are well shown to be dependent on the GCL type, grain size distribution, and the initial moisture content of the subsoil. The field exposure conditions such as external loading and thermal cycles are also shown to affect the rate of hydration of the GCL as well as the maximum moisture content attained.
