GCLs are constructed of two geotextiles encapsulating a layer of low permeability sodium bentonite to create an impermeable liner for use in landfills and ponds.
- Natural liners with minimal environmental impact
- Supplied in rolls for easy installation
- Self-healing bentonite allows it to function even if punctured
- Reinforced for use on slopes, and non-reinforced for use on flat areas
