GCL Bentonite ClayLiner:
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.
