Aritex geosynthetic clay liners combines the unique swelling performance of sodium bentonite with high-strength non-woven and woven geotextiles. Once hydrated, it forms an impermeable barrier agains liquids, water vapor and gases.
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.
Aritex GCL is an extremely versatile clay-based lining product. Once hydrated, the liner becomes an effective barrier against liquids, vapors, and gases. The application scope of Aritex GCLs is very diverse with high efficiency and durability.
