GCLs are composite materials consisting of sodium bentonite clay sandwiched between two geotextile layers, offering a low-permeability barrier against liquids and gases. They’re prevalent in landfill liners, caps, and certain landscaping applications. Geomembranes, on the other hand, are thin, flexible polymer sheets (like HDPE or LLDPE) that serve as barriers in structures such as landfills, ponds, and tanks, and are easily transportable due to their roll-based manufacturing.
