Sodium bentonite Geosynthetic clay liner for sales
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 ≥4000g/m2, width:1m~6m. length:30m or at your request.
(2) Thickness≥6mm, bentonite quality of unit area≥4000g/m2, mass per unit area of
nonwoven geotextile ≥200g/m2, PP woven geotextile≥100g/m2.
Properties:
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.

Features :
1.The permanent waterproof
Because sodium base bentonite is a natural inorganic material, even after a long time or the surrounding environment changes,
also won't happen aging or corrosion phenomena, so the waterproof performance persistence.
2. Compactibility
Sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm,
its permeability is 5 x 10-11m/SEC below, equivalent to 100 times the compactness of 30 cm thickness of clay,
have very strong since the water retention performance.
3.Not affected by temperature
In cold climates will not brittle fracture.
4.Environmental protection
Bentonite as natural inorganic material, non-toxic harmless to human body, no special effects to the environment,
have good environmental performance.
5.Simple and short time of construction
Compared to other waterproofing materials, construction is relatively simple, don't need to be heated and paste.
With bentonite powder and nails, washers, etc are connected and fixed. After construction does not need special
inspection, if it is found that the waterproof defects and easy to maintenance.
GCL is existing waterproof material in construction period of the shortest.
Geosythetic Clay Liners are widely used in waste landfill capping and cutoff walls to contain pollution,mining base seals, canal and dam liners, lakes and other waterproofing projects.
