Sodium Bentonite Geosynthetic Clay Liner
Introduction of GCL:
Geosynthetic Clay Liner is manufactured
by three levels, including two levels of geotextile whose functions are protecting and strengthen to ensure shearing strength and tensile strength, inner content is Sodium bentonite clay. It is manufactured by nature layer silicate inorganic materials and has high expansibility and high water-absorbing capacity, when soak with low permeable capability, whose the main function is anti-seepage.
Description of GCL
Unit weight ≥4000gsm
width of 4-6m
Compared with clay liner ,it has the advantages of small size,light weight ,good flexibility and sea
easy for construction and suitable for uneven settlement.
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.
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.
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.
