Landfill liners (read more on Minerals Technology website)
GCLs can replace compacted clay in liner systems required by 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 combines a geomembrane, a GCL and a partial thickness of a low permeability soil to maximise hydraulic performance and puncture protection.
