Bentonite Geosynthetic Clay Liner

2000 some gcls also include a geomembrane bonded to the bentonite or laminated to the geotextile.

Bentonite geosynthetic clay liner.

A geosynthetic clay liner gcl is comprised of two geotextiles that are needlepunched together encapsulating a layer of sodium bentonite clay between them. Bentomat geosynthetic clay liners the global standard for gcls sodium bentonite based gcls provide an excellent hydraulic barrier in applications where leachate in direct contact with the gcl is relatively non aggressive or in composite lining applications where the gcl is overlain by a thermally welded geomembrane and hydrates from uptake. Geosynthetic clay lineris also named sodium bentonite composite waterproof pad. Bentotex is a geosynthetic clay liner gcl.

Geosynthetic clay liners gcls are factory manufactured hydraulic barriers consisting of a thin layer of sodium bentonite na b clay approximately 3 5 kg m 2 sandwiched between two geotextiles that are bonded by needle punching or stitching shackelford et al. The powdered bentonite clay is sandwiched between a woven and non woven geotextile resulting in a very strong robust product. Geosynthetic clay liners gcls are factory manufactured hydraulic barriers consisting of a layer of bentonite or other very low permeability material supported by geotextiles and or geomembranes mechanically held together by needling stitching or chemical adhesives. Geosynthetic clay liners gcls are geotextile and bentonite composites typically sodium bentonite sandwiched between two layers of geotextile engineered for a variety of environmental containment applications.

This is to make high swelling sodium bentonite filling into the inside between special composite geotextile and non woven fabric. It is an innovative composite product manufactured using the naturally occurring bentonite clay resource. Bentoline is mined volcanic ash that fell millions of years ago and got laid in seams under the sea. They have the unique ability to seal around penetrations self heal punctures and self seam at the overlaps.

Bentonite geosynthetic clay liners three geosynthetic clay liners a specialist product range comprising bentoline and bentoline cl. Geosynthetic clay liners gcls combine geosynthetics with sodium bentonite clay to form a highly impermeable barrier that often replaces thick layers of expensive compacted clay.
