NaBento® is a geosynthetic clay liner.

By using NaBento®, conventional mineral liners are made much more reliable and economic. This laminated composite is approx. 1 cm thick and has high quality bentonite contained within various textile supporting layers. The components are sewn together in a special way to provide high internal shear strength. The supporting geotextiles, sewn seams and nonwoven aero-fabric are designed to act together with the bentonite and ensure that NaBento® provides a long-term impermeable barrier.

NaBento® is manufactured to suit the particular application. The type and quantity of bentonite can be specified as well as the particular synthetic raw material, ancillary fittings and detailed design. To improve the drying performance and the shear strength of the adjacent soils or other materials, a special coating can be applied to the surface.

The installation of NaBento® is straightforward and generally independent of the weather. Bentonite powder/paste or a special adhesive is used to seal the overlapped joint during installation.

Typical applications: stable sealing of steep earthwork slopes up to 1:1.75 water barriers in civil and hydraulic engineering groundwater protection in road and railway construction capping of landfill sites tunnel lining

Properties: large surface area, flexible water barrier accomodates high settlement and resists erosion high internal shear strength straightforward and generally weather independent installation factory-manufactured and quality controlled
