Overview
Hongxiang Geosynthetic clay liner is composed of high dilatability of sodium base bentonite filling between the special composite geotextile and nonwoven fabric, made by the method of acupuncture or suture composite impervious material. Use acupuncture into geosynthetic clay liner can form many small fiber space, make the bentonite particles can't flow in one direction, when under the influence of water within the mat forming uniform density of colloidal waterproof layer, prevent the leakage of water.
Bentonite has the expansion of the water characteristics. General calcium base bentonite expands, its expansion is only about 3 times their own size; And sodium base bentonite adsorption 5 times its own weight of water in case of water, Volume expansion to the original 15 to 17 times above; Lock sodium base bentonite in the middle of the two layers of geosynthetic materials, protecting and strengthening the role of, Make the GCL has a certain overall shear strength.
For different projects,it can combine HDPE liner for better waterproof.
Advantages:
Unique self-sealing attributes that reduces the risk of punctures and leakage.
Excellent shear resistance properties due to needlepoint reinforcement.
Reduced leakage by a factor of 30 over compacted clay.
Better hydraulic performance.
Ease of installation. & Increased air space.
Cost effective: one truckload of GCL replaces 200 truckloads of clay.
Common Applications:
Irrigation ponds, canals, reservoirs, & ditches
Landfills & dams
Agricultural
Municipal
Aquaculture & horticulture
Liners & covers
Landfill liners, covers, & caps
Liquid containment
Secondary containment
Wastewater lagoons
Mining-heap leach & slag tailings
Golf courses & decorative ponds
Solid waste containment

COMPANY INFORMATION:
Hongxiang New Geo-Material Co.,Ltd in leader of the geotextile, geomembrane and GCL in China. It was set up in June,1987 and become a provincial enterprise in Oct.1997. It occupies a land of 300,000 square meters, with total asset RMB320,000,000. There are 1200employees, among them, there are 268 professional and technical personnel. We have 56 production lines mainly produce needle-punched geotextile, filament spunbond geotextile, high strength geotextile, 3-layer co-extrusion geomembrane, dripping membrane, heart treated compound geomembrane 8m in width. PE/PVC/EVA press prolong geombrane, textured geomembrane, ant-skid geomembrane, uniaxial geogrid, biaxial geogrid, steel-plastic geogrid, geocell, geomat, woven geotextile, split yarn woven geotextile and so on. Owning the word leading production line of geosynthetics. We have our own R&D department and our own test room which reach to national level.
Our annual productivity is as below: 50 million square meters of needle-punched geotextile; 55 million square meters of compound geomembrane; 9,000 metric tons of PE geomembrane; 36 million square meters of macromolecule waterproof materials; 8 million square meters of geosynthetic clay liners (GCL); 5 million square meters of single direction geogrid; 8 million square meters of double-direction geogrid; 1 million square meters of geocell; 4 million square meters of geonet; 3 million square meters of tri-dimensional geomat; 10 million square meters of woven geotextile; 9,000 metric tons of geomembrane; 300 metric tons of PP long fiber; 4,000 metric tons of PP long fiber; 6 million plastic woven bags.
