Product Description

Waterproof material 4000g geosynthetic clay liners (bentonite gcl)

Waterproof material 4000g geosynthetic clay liners (bentonite gcl) is a kind of special used for artificial lake water, landfill, underground garage, the roof garden, pool, oil and chemical storage area such as seepage prevention of geosynthetic materials, it is made of high dilatability of sodium base bentonite filling between the special composite geotextile and non-woven fabric, with acupuncture law into bentonite seepage control pad can form many small fiber space, is bentonite particles can not be like a direction, when under the influence of water within the mat forming uniform density of colloidal membrane, prevent the leakage of water.

Technical Index
Product Feature

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 ˉ 11 below, equivalent to 100 times the compactness of 30 cm thickness of clay, have very strong since the water retention performance.


Permanent waterproof performance: 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.


Construction simple and short time limit: 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.


Integration: sodium base bentonite under water, the swelling capacity of 20-28 times, even if the concrete structure vibration and settlement, within the GCL bentonite can also repair the crack on the surface of the concrete within 2 mm.


Green: bentonite as natural inorganic material, non-toxic harmless to human body, no special effects to the environment, have good environmental performance.
