Description

Sodium Bentonite is a naturally occurring clay with hundreds of uses. Comprising mainly montmorillonite, a layered clay mineral with broad flat platelets which are ideally shaped to provide a hydraulic barrier. Sodium ions located between these platelets allow water to hydrate the bentonite in an absorption reaction that results in the bentonites swelling characteristics. swells when contacted with water approximately 900% by volume or 700% by weight. When hydrated under confinement, the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay. This swelling allows the bentonite to seal around penetrations, giving the GCL self sealing characteristics. During hydration, a confined layer of dry bentonite changes into a dense monolithic mass with no observable individual particles. A fully hydrated sodium bentonite layer can have a hydraulic conductivity of approximately one hundred times lower than a typical compacted clay liner (CCL). Because of their low hydraulic conductivity, GCLs are used mainly as a replacement for thick, difficult to build, compacted clay liners to provide a barrier to liquids and gases. Permathene supply and install a range of GCL's from light to heavy grades. These are high performance environmental liner comprised of geosynthetic carrier components integrated with a layer of low permeability sodium bentonite. The rolls are supplied in wide widths, minimising seams. Installation is fast.
