Sodium bentonite waterproofing blanket mat Geosynthetic Clay Liner GCL
Geosynthetic clay liners (GCL) are an established sealing product in the geoenvironmental industry. Waterproof Rolling Material Geosynthetic Clay Liner are used in landfill caps and base liner applications under roads, railways, secondary containment for above ground tank farms, as well as within various other containment structures such as dams, canals, ponds, rivers and lakes. Anti-Seepage Geosynthetic Clay Liner are also used for waterproofing of buildings and other similar structures.
We have Natural Bentonite Geosynthetic Clay Liner and Geosynthetic Clay Liner With Geomembrane.
Geosynthetic Clay Liner(gcl) Applications:
The water proof bentonite pad is mainly used in penetration-proof,airproof &separation in rubbish burying square,man-made lake,channel,pool,basement,subway,etc.
Anti-seepage Geosynthetic Clay Liner Feature
1. Compactness: sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm, its permeability is & x 10 m/SEC 11 below, equivalent to 100 times the compactness of 30 cm thickness of clay, have very strong since the water retention performance.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.
Green: bentonite as natural inorganic material, non-toxic harmless to human body, no special effects to the environment, have good environmental performance.
