NaBento® - Geosynthetic Clay Liner Unique Product for Optimum Sealing Performance □ HUESKER Ideen. Ingenieure. Innovationen.

NaBento – Combining the Best of Nature and Technology The NaBento geosynthetic clay liner (GCL) is a composite product, a mere 1 cm thick, comprising high-grade bentonite sandwiched between various geotextile cover and supporting layers. The main constituent of the incorporated bentonite is montmorillonite, a highly swellable, three-layer clay mineral. The swelling action of the encapsulated bentonite due to water absorption is compounded by the loads acting on the NaBento GCL to create a waterproof clay barrier. The water permeability progressively falls as the loads increase: achievable values...

Production flexibility NaBento is manufactured on state-of-the-art production lines. Apart from our time-tested standard models, we also fabricate purpose-designed GCLs to our customers' specifications. The use of alternative raw materials, higher component weights per unit area or the integration of additional polymer/geotextile layers allows fine-tuning of the product properties to local conditions. Enhanced performance thanks to coating ¡ he surface of NaBento RL-N and NaBento RL-C is coated with ¡T bitumen and expanded shale to boost the product's long-term external shear strength (friction)...

Geosynthetic Clay Liner with a Reputation for Versatility Consistently guaranteed quality Quality begins with the technical design of NaBento and the selection of its constituent materials. Stringent incoming goods inspections – covering everything from the bentonite to the geotextile components – guarantee that all materials exhibit the required properties. Weight and thickness are constantly checked during manufacture. Moreover, the achievement of all critical mechanical and hydraulic parameters – above all, permittivity (ψ) – is ensured by means of systematic internal and external surveillance....
