Waterproof Sodium Bentonite Liner Geosynthetic Clay Liners for
Landfill Project
Geosynthetic clay liner Concrete protection mat (GCL)
-geosynthetic clay liners ,lake mat ,GCL waterproof material
Geosynthetic clay liner (GCL) is composed of high dilatability of
sodium base bentonite filling between the special composite
geotextile and nonwoven fabric. It made by the method of
acupuncture or suture composite impervious material. Use
acupuncture into GCL can form many small fiber space, make the
bentonite particles can't flow in one direction, when under the
influence of water within the mat forming uniform density of
colloidal waterproof layer, prevent the leakage of water.
For different projects, it can combine HDPE liner for better
waterproof. Bentonite has the expansion of the water
characteristics. General calcium base bentonite expands, its
expansion is only about 3 times their own size; And sodium base
bentonite adsorption 5 times its own weight of water in case of
water, Volume expansion to the original 15 to 17 times above; The
geotextile and nonwoven fabric lock sodium base bentonite in the
middle of the two layers of geosynthetic materials, play a
protecting and strengthening role , make the GCL has a certain
overall shear strength.

Application:
This Bentonite production line is usded to bond 3layers of top
geotextile, middle bentonite sand, and down plastic woven film.
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.
The production line processing of finished products with high peel
strength, strong pulling hardness, low permeability.
