Current and trending alternatives to conventional compacted clay liners are GCLs or geosynthetic clay liners or prefabricated bentonite clay liners. An innovative geosynthetic product, it is extensively used in various civil engineering and geoenvironmental engineering applications, primarily in irrigation. Geosynthetic Clay Liners provide an alternative to conventional Compacted Clay Liners by replacing a thick section of compacted clay with a thin layer of pure sodium bentonite. The benefits of this approach include easy installation and more useable air-space in landfill applications
Bentonite is a natural sodium sealant which, when hydrated, will swell to create a low permeability liner offering approximately the same hydraulic protection as one metre of compacted clay. Replacing this thick clay liner with an easily deployed GCL can result in an increase in airspace, creating increased capacity and therefore more income. Description. The Geosynthetic Clay Liners or GCLs are an integrated matrix of a layer of bentonite encapsulated by woven and nonwoven geotextiles on either side. The three layers together then undergo needle punching and thermal locking for reinforcement and securing the fibers, further improving strength and performance The high swelling characteristics of the bentonite clay component in the GCL will work to seal the leak in the GM. However, owners, engineers, and regulators need to be aware consolidation water from a GCL can be of detectable quantity and confused as leakage as the landfill cell is filled CETCO, a leader in geosynthetic clay liners (GCLs) manufacturing, has released the BENTOMAT DN-HS geosynthetic clay liner, a new addition to the BENTOMAT product portfolio that uses proprietary, high-density needlepunching technology to generate superior peak shear strength properties for slope stability

The fine powder forms when volcanic ash ages. It's named after Fort Benton, WY, which has a lot of it
GCL - Geosynthetic Clay Liner is a woven fabric like material sandwich with bentonite clay in the middle. When installed correctly it behaves like a geomembrane, resulting lower permeability slowing down any seepage out of the dam. Due to bentonite clay having a very low hydraulic conductivity it makes for an effective GCL The sodium bentonite clay utilized in our BentoLiner® GCL is a naturally occurring clay mineral that swells as liquid enters between its clay platelets. When hydrated under confinement, the bentonite swells to form a low permeability clay layer with a hydraulic conductivity value of 5x10-9 cm/sec A. Accessory Bentonite.

Enhanced soil liners, using bentonite clay, are another option, and for large ponds, this is known as a pretty cost effective method.However, this requires someone who really knows what they are doing and/or a chemical product known ESS13 (Environmental Soil Sealant). The beauty, though, of both enhanced soil and natural clay liners is that they last many. The permeability of soil and bentonite mix is found out by variable head permeability test. For the test the mixture of soil and bentonite is compacted to wet off optimum. C. Soil as liner material Resultant mix of liner should have a minimum of 20 to 30% fines and the percentage gravel should not exceed 30%
A geosynthetic clay liner is provided for installation in landfill sites equipped with lower drainage systems. The self-sealing bentonite mat precludes substantial migration of bentonite downward during activation thereby avoiding clogging of the drainage systems with activated bentonite. Overlap extensions disposed on outer edges of the liners effectively contain the activated bentonite To prevent the liner sliding down the dam wall, anchor Bentotex rolls into a trench at the crest of the dam. Unroll Bentotex down the dam face using a backhoe and spreader bar assembly. Finally, seal the overlaps with bentonite clay granules and cover the Geosynthetic Clay Liner with 30cm of soil. Once laid, avoid vehicular traffic eosynthetic clay liners (GCL) are hydraulic barriers made of clay bonded to a single geosynthetic layer or to multiple geosynthetic layers. Because of its low permeability, swelling capacity and relative abundance, natural sodium bentonite is the preferred clay component of GCL. A wide range of mate Sanitary Landfill Liners When hydrated, sodium bentonite swells and forms an impermeable gel seal which makes an excellent landfill liner.Bentonite is all natural and is more cost efficient than synthetic liners. Typically a layer of bentonite is applied to a thickness of up to 24 inches before the deposition process
Bentonite-enhanced sand mixtures (BES) are increasingly being used as landfill liners because they are an economic alternative to compacted clay when suitable clay is not locally available. As the main function of the liner is to prevent, or at least minimise, the movement of water out of the waste disposal facility, BES should satisfy three. If you want a permanent pond, there are really three basic options: 1) excavation into local impermeable soils-with compacting, 2) clay liners or 3) bentonite or chemical additives. Soil conditions vary substantially around the country. In some areas the soil has a heavy clay component Geotextile clay liners are made up of two layers of geotextiles that surround a layer of sodium bentonite. The sodium bentonite layer has a number of advantages, including low permeability and the potential to function as a natural sealant Bentonite Geosynthetic Clay Liner is generally not suitable for construction under negative temperature. Under negative temperature, the roof insulation layer and leveling layer are not easy to dry.
