Geosynthetic Clay Liner

Geosynthetic Clay Liners (GCLs) are high-performance environmental liners consisting of two needle-punched geotextile layers encapsulating a layer of sodium bentonite for sealing.

These high-strength durable geotextiles are used primarily as a substitute for compacted clay liners in areas such as landfills, secondary containments, and surface impoundments. They can also be used in irrigation conservation, as natural pool liners, and effluent ponds.
