Geosynthetic Clay Liners are a kind of needle-punched watertight composites which are filled with sodium bentonite to combine the two woven and nonwoven geotextile fabrics to create a natural barrier. As for the substances of Tinhy’s Geosynthetic Clay Liners, we usually join them together by needling or using chemical adhesives.
Tinhy’s GCLs can be widely applied as an alternative for compacted clay liners in many environmental projects, such as landfills, reservoirs, bridges, etc. The sodium bentonite in the Geosynthetic Clay Liners can grow automatically to constitute a low penetrability clay layer to protect the compacted clay.
Geosynthetic Clay Liners (GCLs) are a type of composites which sandwich the sodium bentonite between the two woven and nonwoven geotextile fabrics, which can be applied in various environmental containment projects. The geotextiles farics are able to perform a durable resistance to physical and chemical break-down in terrible conditions while both the sodium bentonite’s high swelling capacity and its low permeability can effectively form into a hydraulic seal. Our GCLs can similarly protect the soil compared with that of compacted clay while the advantage of great tensile and peeling strength can assist to make the Geosynthetic Clay Liner fit a wide range of composite liner systems, landfills anti-seepage or watertight projects, tailings waste handling, etc.
Tinhy’s Geosynthetic Clay Liners can be used for replacing a thick section of compacted clay in conventional compacted clay liners with a thin layer of complete sodium bentonite. Taking the advantages of easy installation, great hydraulic performance and adaptability to various weather conditions, most of the landfill anti-seepage projects can be handled and fulfilled by using ordinary equipments. Our GCLs also own featured self-sealing attributes, which can reduce the risk of failures come from negative environment and processing conditions.
