Bentofix® X multicomponent geosynthetic clay liners (GCL)
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.
Solutions with Bentofix® X
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.
Barrier against critical liquids
Improves the barrier performance and acts as a chemical protection in landfill applications, groundwater protection, soil encapsulation and brown-field/contaminated land developments, mining and tank farms.
Advantages of Bentofix® X geosynthetic clay liners
Bentofix® X GCLs exemplify how geosynthetics perform best: by interacting with natural elements to create something stronger or more secure. The main advantage of Bentofix® X is that it can be used for versatile sealing applications.
Two independent sealing barriers
The PE extrusion-coated barrier improves the sealing performance and acts as a protection for the bentonite against ion ion exchange and against more challenging chemicals, and as an immediate gas barrier.
Less cover soil, better performance
Bentofix® X now achieves an increased resistance against desiccation while requiring less cover soil when compared to standard GCL applications.
Durable long-term shear strength
Bentofix® X is available with smooth (X2) or textured (X5F and X10F) PE coating, offering unique advantages regarding slope stability. The coating is also homogeneously extruded and firmly bonded to the GCL. No shrinkage or delamination caused in climates with high temperatures.
