Sodium bentonite Geosynthetic clay liner
GCL are high performance environmental liners comprised of a layer of low-permeability sodium bentonite combined with geosynthetic carriers, such as woven and/or nonwoven geotextiles, and in some cases polymer geomembranes. GCL have been proven to provide better engineered performance and durability than several feet of compacted clay with a total composite thickness of less than one quarter of an inch.
About the clay material, it is usually bentonite, which sandwiched between two layers geotextiles.
This lining mechanism is mechanically bonded by needle punching from one nonwoven geotextile
through the bentonite to the other nonwoven or woven geotextile.
The bentonite swells and extrudes through the geotextile fabric at the overlap, forming a seal by
producing a dense and uniform clay barrier with the same hydraulic qualities in all parts of the
clay liner
Bentonite is a natural clay formed by weathering of volcanic ash. Its chief constituent is the clay
mineral montmorillonite. Bentonite is distinguished from other clays by its extreme fineness,
highly absorbent nature and curious property of swelling in water.
(1)GCL mass per unit area â?¥4000g/m2, width:1m~6m. length:30m or at your request.
(2) Thicknessâ?¥6mm, bentonite quality of unit areaâ?¥4000g/m2, mass per unit area of
nonwoven geotextile â?¥200g/m2, PP woven geotextileâ?¥100g/m2.
Properties:
GCL not only have all the characteristics of geotextile material, but also has excellent
water (seepage) performance.
1) Good waterproof capacity, sodium bentonite can form a gel layer which does not permit the penetration of water
2) It has strong ability to fit the uneven sedimentation well.
3) Good water-keeping and self-fix capacity
4.)Permanent waterproof capacity, sodium bentonite is natural inorganic mineral material, there is no corrosion and age happened to sodium bentonite
5)sodium bentonite is harmless to human being and environment.
6)easy operation, it can be fixed in nail and gasket, it can reduce the building time greatly.
Advantages:
It was possible to order the exact length of liner required across the channel to be supplied on one roll. This eliminated the need to â??cut and pasteâ?? the liner.
The material is suitable for sites where no clay source was available.
Disadvantages:
The material is very heavy, difficult to handle, and labour intensive to install.
Features:
Improved leakage performance
Permanent waterproof performance
Simple construction and short time limit for a project.
Not influenced by air temperature.
A kind of green material and good to environmental protection.
More versatile than compacted clay
Increased airspace and liner efficiency
Geosynthetic clay liner bentonite waterproof blanket (gcl) is earthwork composite material that is specially used for anti-seepage of man-made lake waterscape, landfill yard, underground garage, building roof garden, water tank, oil depot and chemical pile yard what is gcl? gcl is blanket shape fabric that is produced by filling sodium base bentonite with high expansion between special composite earthwork cloth and non-woven cloth and locking bentonite on lower composite fabric through upper non-woven cloth fabric by special needle embroidering method. Bentonite anti-seepage liner produced by needle embroidering method can form many small fiber spaces, which prevent bentonite particles from moving in one direction, rubber head water layer with uniform high density is formed in the liner when meeting water so as to prevent water seepage effectively. Product application It is mainly used in various environmental protection projects such as waste landfill yard, underground reservoir and underground infrastructure, solves sealing, isolation and anti-seepage problems, and has good effect and strong damage resistance Quick details Type: Geosynthetic clay liner Place of origin: Shandong, china (mainland) Brand name: Tianyan Model number: 4*30 Material: Gcl Specification: As your demand Weight: 4000-6000g/m2 Width: 3m-6m , as your demand Standard: Astm Color: Black or white Samples: Free

Ball Clay: A member of kaolinite family, Ball Clay is renowned for its plasticity and green strength. They consists varying proportions of kaolinite, mica and quartz, with small amounts of organic matter and other minerals, and are commercially values because they increase the workability and strength of various ceramic bodies and have white or near white firing characteristics. Ball clay is processed to minimize the levels of coarse particles. This enhances better workability and higher strength. Applications : It forms a major part of many ceramic applications, including sanitary ware, tiles, table wares and to an increasing extent non-ceramic applications like functional fillers and advanced application for example technical ceramics.
