  • Prefabricated with a sodium bentonite clay between the two nonwoven geotextiles or between top nonwoven and bottom woven geotextiles.
  • These are needle punched together to increase the internal shear resistance.
  • Once hydrated GCLs are effective as a barrier for gases and liquids.
  • Also, available GCLs with HDPE Geomembrane / PE coating as carrier layer.
