Résumé :
|
Modern landfill liners typically contain several geosynthetics and natural components integrated into a system whose primary function is the containment of waste and leachate. One of these hydraulic barrier components is reprensented by Geosynthetic Clay Liners (GCL). The GCLs are factory manufactured hydraulic barriers consisting of bentonite clay supported by geotextiles or geomembranes. Since the waterproffing function is assured by the bentonite clay it is therefore advisable to verify its chemical compatibility with the leachate and its effect upon the hydraulic conductivity value.
