G-Gcl:
GCLS are an established sealing product in the environmental industry. Rolled out like a carpet to provide a durable impermeable liner, geosynthetic clay liners consist of a layer of high swelling sodium benonite, sandwiched between two geotextiles, by different textiles, manufactured GCL, G-GCL, is mechanically bonded by needle-punching from one nonwoven or woven geotextile.
Sodium Bentonite is a natural 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 the contacted with water approximately 900% by volume or 700% by weight. When hydrated under containment, 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 pentetrations, 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 hydraulic conductivity of approximately one hundred times lower than a typical compacted clay liner.

APPLICATION: roads, railways, ground tank farms, dams, canals, ponds, rivers and lakes.
