Product catalog summary

Introduction to Bentofix® Geosynthetic Clay Liners (GCLs)
Bentofix® is a pioneering product in the field of geosynthetic clay liners, known for its needle-punched technology that enhances sealing efficiency and durability. It combines natural and synthetic materials to create a robust barrier suitable for various sealing applications.

Material Composition and Technology
The GCLs consist of two durable geotextile layers encapsulating a core of high-swelling sodium bentonite powder. The needle-punching process bonds these layers, providing multi-directional shear strength and self-sealing capabilities. The Thermal Lock process further enhances internal shear strength and interface friction.

Advantages of Bentofix®

Cost-Effectiveness and Performance: Bentofix® is more cost-effective and performs better under differential settlement compared to compacted clay liners.
Immediate and Long-Term Sealing: The high-swelling bentonite powder ensures immediate sealing and long-term performance, with the ability to self-seal and re-heal.
Installation Benefits: Available in wide rolls, Bentofix® is quick and easy to install, reducing labor and time costs.

Applications
Bentofix® is versatile and can be used in landfill caps, environmental protection under infrastructure, water containment, structural waterproofing, and more. It is certified for use in various applications, including landfill caps and closures.

Performance and Testing
Figures in the document illustrate the superior performance of Bentofix® in terms of shear stress, water content correlation, and permeation values under different conditions.

Conclusion
Bentofix® GCLs offer a durable, low-permeable sealing system that combines the strengths of geotextiles and bentonite, making it a reliable choice for a wide range of environmental and structural applications.

BENTOFIX® Bentofix® Thermal Lock geosynthetic clay liners (GCLs) - also known as geosynthetic clay barriers (GBR-C) - are 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. Bentofix® geosynthetic clay liners (GCL) exemplify how geosynthetics perform best: by interacting with natural elements to create something stronger or more secure.

ADVANTAGE 1 Bentofix® Thermal Lock replaces other GCLs as well as other soil barriers on steep side slopes and assures low permeability without sacrificing slope stability. Explanation: Bentofix® is uniformly needle-punched with over 2 million fibres/m². This results in a uniform, directionally-independent shear stress transfer. Thermal Lock additionaly improves the pull-out resistance and the interface friction. (1) The nonwoven protects against installation stress and increases the interface friction performance. (2) The bentonite powder acts as an immediate barrier. (3) The slit-film woven...
