Geosynthetic Clay Liners

Geosynthetic Clay Liners (GCLs) are engineered materials used to contain and prevent the leakage of liquids in landfills and other containment systems. They consist of a layer of bentonite clay sandwiched between geotextiles or geomembranes. When hydrated, the clay swells, creating an effective, low-permeability barrier that blocks liquids and gases. GCLs are flexible, easy to install, and cost-effective, making them popular choices for environmental protection, waste containment, and remediation projects. Their ability to conform to irregular surfaces ensures a tight seal, maintaining containment integrity over time.
