Geosynthetic clay liner enhances containment with multicomponent barrier

Bentofix® + X is an advanced geosynthetic clay liner (GCL) designed to provide superior sealing performance across various applications. This needle-punched, fibre-reinforced composite integrates two durable geotextile outer layers with a uniform core of high-swelling sodium bentonite powder, forming a multidirectional, shear-resistant hydraulic barrier. The addition of an extrusion-coated polyethylene layer enhances the liner’s resistance to permeation, gas intrusion, and desiccation, making it ideal for landfill engineering, mining operations, hydraulic structures, and groundwater protection projects. Bentofix® + X offers a robust, self-sealing solution that ensures long-term containment and environmental safety.

Bentofix® + X

Bentofix® + X Thermal Lock geosynthetic clay liners (GCLs) – also known as geosyn-thetic clay barriers (GBR-C) – are at the forefront of innovation in the mining industry. These needle-punched, reinforced composites that combine two durable geotextile outer layers and a uniform core of high-swelling powder sodium bentonite clay. This forms a uniform, multi-directional, shear-resistant hydraulic barrier with self-sealing and re-healing characteristics. With its outperforming coating, Bentofix® + X types allow enhanced application fields and shear strength transmitting applications.

Landfill engineering and mining

Serving as an effective barrier against
groundwater and surface water contamination.

Application advantages of Bentofix® + X

Bentofix® + X serves as a robust barrier against groundwater and surface water contamination. This is crucial in landfill applications to prevent leachate, which can contain hazardous materials, from contaminating the surrounding environment. The additional oxidative resistance of the coating increases the durability of the product.

Hydraulic structures (dams, canals, reservoirs)

Protecting against water permeation in dams, canals, and reservoirs.

Application advantages of Bentofix® + X

For hydraulic structures like dams, canals, and reservoirs, Bentofix® + X ensures protection against water permeation. This is vital for maintaining the structural integrity of these constructions and for preventing water loss or seepage that could weaken the structures or cause environmental issues.

The novelty of Bentofix® + X

Extrusion-coated polyethylene liner: This feature of Bentofix® + X typifies the innovative approach of the product, provid-ing an immediate and augmented barrier against gases and radon, a notable advancement in GCL technology.

Comprehensive applications and advantages

Bentofix® X types are multicomponent geosynthetic clay liners (GCL) – also known as geosynthetic clay barriers (GBR-C).
