Description:
GCL is a new environmentally friendly composite waterproof
impermeable material, it’s bentonite particles filled in woven and
nonwoven geotextile between the upper layer of non-woven fibers
through the bentonite particles, through a special process and
equipment, with the acupuncture method of weaving on the link in
the lower composite. Geosynthetic Clay Liner has the advantages of
small size, light weight, good flexibility and seal easy for
construction and suitable for uneven settlement. The GCL normally
used in environment engineering or landfill emissions, underground
reservoirs, underground infrastructure construction projects,
sealing solution, segregation, anti-leakage, good effect,
anti-destructive.

Advantages:
1. Compactness: sodium bentonite in a state of formation of high
density diaphragm during water pressure in thickness of about 3mm ,
its permeability equivalent to 100 times of 30cm thickness clay
liner, with a strong self-protection water performance.
2. With a permanent waterproof performance: because of natural
sodium bentonite -based inorganic material , even after a very long
time or changes in the surrounding environment , aging or corrosion
does not occur.
3. Simple construction and short construction period: comparing to
other waterproof materials, GCL is relatively simple and does not
require heating and paste, just bentonite powder and nails ,
washers, etc. After construction does not require special
inspection , if found defective water is also easy to repair.
4. Subject to temperature effects: In cold weather conditions will
not be brittle .
5. Waterproofing materials and objects Integration: sodium
bentonite with a capacity of 20-28 times the expansion , even
concrete structures vibrate and subsidence , GCL bentonite within
less than 2mm can repair cracks in the concrete surface.
6. Environment friendly: Bentonite is a natural inorganic material
, harmless non-toxic, no particular effect on the environment ,
with good environmental performance.
