Are Bentonite GCL liners  a natural product?

Geosynthetic Clay Liners (GCLs) are engineered materials that combine natural sodium bentonite clay with geotextiles or geomembranes. The natural bentonite clay is the key component in GCLs, known for its swelling and impermeable properties. This clay is typically sandwiched between layers of geotextiles or geomembranes, which serve to enhance the liner’s mechanical and hydraulic performance.

So while GCLs contain natural clay, they are considered geosynthetic materials due to their engineered composition, combining the benefits of both natural clay and synthetic components to create an effective barrier for various applications such as landfill liners and containment systems.
