Geosynthetic clay liner: Bentofix® Home » Products » Geomembranes » Bentofix® Bentofix® geosynthetic clay liners (GCLs) Bentofix®, 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. Typical solutions with Bentofix® Landfill caps, closures and base seal Environmental protection under roads, railways, airports Dams and dykes Water containment and pond applications Structural waterproofing Secondary containment Mining applications Tunnels Project advantages Versatile sealing applications possible Immediate sealing and long-term performance with high swellable sodium bentonite powder Outperforms compacted clay liners Robust geotextiles encapsulate and contain the bentonite Uniform needle-punching provides multi-directional shear strength Thermal Lock process increases internal shear strength and interface friction angles Self-sealing length overlaps; with BFG types all overlaps self-seal Quick, easy and cost effective to install Selected advantages of Bentofix® Conservative correlation of internal shear stress, dependent on the Bentofix® peel strength (hydrated under low confining stress) Bentofix® 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 additionally improves the pull-out resistance and the interface friction. Performance of powdered Bentofix® bentonite compared to granular bentonite in correlation to water content and gas permittivity. Bentofix® advantage 2 Bentofix® acts immediately as a sealing element. The explanation: high-swelling bentonite powder, uniformly distributed bentonite powder, large bentonite swelling surface and smaller air voids to close. Precipitation drainage run-off and permeation values of GCLs under 1m cover soil in German climate. Bentofix® advantage 3 Bentofix® utilises the advantages of three high-performance components in one geocomposite: The nonwoven protects against installation stress and increases the interface friction performance. The bentonite powder acts as an immediate barrier. The slit-film woven gives the product the dimension stability and makes the product stable for installation handling. The result of this trio, combined with the needle-punching and Thermal Lock: A durable, low-permeable sealing system.
