Also known as geosynthetic clay barrier (GBR-C) is a needle-punched, fibre-reinforced composite that combines two durable geotextile outer layers and a uniform core of high-swelling sodium bentonite powder with an additional polyethylene extrusion-coated barrier. This forms a multi-directional, shear-resistant, hydraulic, multicomponent barrier with self-sealing and rehealing characteristics.
Improves permeation resistance against high water heads in hydraulic engineering applications, storage ponds/lagoons and waterproofing.
Provides improved and immediate gas resistance in landfills, containment and waterproofing applications.
Prevents piping if subbase is a coarse aggregate in hydraulic engineering applications and storage ponds/lagoons.
Protects against ion exchange in the following applications: landfill engineering, containment, groundwater protection, soil encapsulation and brownfield/contaminated land developments, hydraulic engineering, mining, tank farms, storage ponds/lagoons and waterproofing.
Keeps bentonite moist and prevents bentonite dehydration in landfill applications, containment, groundwater protection, soil encapsulation and brownfield/contaminated land developments, hydraulic engineering, mining and tank farms.
Prevents root penetration in landfill applications, containment, groundwater protection, soil encapsulation and brownfield/contaminated land developments, hydraulic engineering and storage ponds/lagoons.
Improves the barrier performance and acts as a chemical protection in landfill applications, groundwater protection, soil encapsulation and brownfield/contaminated land developments, mining and tank farms.
