Multicomponent geosynthetic clay liner: Bentofix® X

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.

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 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.
