GCLs can replace compacted clay in liner systems required in many regulations. They effectively minimise system leakage by providing "intimate contact" with the overlying geomembrane.


This allows a GCL based liner to outperform a compacted clay-based system. Another popular design option is to combine a geomembrane, a GCL and a partial thickness of a low permeability soil to maximise both hydraulic performance and puncture protection.

  • Used in place of compacted clay or geomembranes
  • Good slope stability characteristics
  • Self-sealing if punctured
  • Good synergistic affect with geomembrane in composite liners
