Aritex geosynthetic clay liners (GCLs) are high performance environmental liners used in environmental containment applications. Aritex GCLs consist of two layers of geotextiles surrounding a layer of low permeability sodium bentonite that are needle punched together to increase internal shear resistance. The geotextiles offer a long lasting resistance to physical or chemical break-down in harsh elements, while the bentonite’s high swelling capacity and low permeability provide an effective hydraulic seal.
