Geosynthetic Clay Liners (GCL)

GCLs are composed of a granular layer of sodium bentonite clay encapsulated between two needle-punched geotextiles. When hydrated, the granules swell up to 15 times of their initial volume, forming a watertight layer that is equivalent to a clay thickness from 60 to 90 cm. Sealing of the joints is done by overlapping the panels, as a result, the installation does not require a specialized team.

PropERTIES

  • Mat composed of chemically stable geotextiles
  • Internal reinforcement by needle-punching
  • 100% sodium bentonite

ADvantages

  • No loss of granules through the pores of the geotextile contrary to powder based GCLs
  • Allows a great economy of clay
  • Quick and easy installation
  • Overlap sealing

Applications

  • Landfills
  • Mining areas
  • Various basins and channels
