Geosynthetic Clay Liner(GCL)
Product Description
Geosynthetic clay liners’ weight is uniform,permeability is strong,flexible is good,and can be suitable for the uneven
foundation settlement,and to prevent the soil loss,cracks and other defects with a good healing.
Product Features
1. Environment friendly
Liu Fangzi GCL is made of natural raw materials of sodium-bentonite.It is raw and natural materials,;aging and corrosion seldom happen. It can keep its quality and then it
does not cause any injuries and pollution for human and the environment. It is not only waterproof, but also has
good ventilation performance. It can stick up for the exchange of the ecological environment. It is a pure natural, new, green waterproof material.
2. Permanent waterproof, excellent performance
Natural sodium bentonite was formed billions of years ago.
Its waterproof properties are much more durable than that of the buildings. Sodium bentonite would transform to
high density septum under hydro pressure. When The thickness is 3mm, the permeability is below a*10-11/sec(a=1~9), which equals to the density of 100 times of the clay with 30 mm thickness. Water retention performance
is evident.
3. Easy to construct
Bentonite powder, nails and washers are enough for connection and fixation. Construction is not constrained by
weather conditions and it could be taken under cold or wet conditions. Bentonite powder is spread on overlap
point. When water comes, GCL would be overlapped automatically. It is so far the only material that starts the
waterproof effect by water in the world. It is not necessary to take additional examination when the construction is
completed. The repair works are easy in case of waterproof defects. Among the existing waterproof materials,
GCLs construction period is the shortest and its operation is the easiest. It has an eminent effect on shortening the
construction period as well as saving the cost.
4. Strong Self-Restore Capacity
The integration between waterproof material and its target enables GCL a 20~28 times swelling volume. Even if
concrete structure trembles or subsides, the bentonite in GCL would restore the crack of 2mm or below on the
concrete structure immediately. Even if the diameter of perforation reaches 30 mm, the restoration will be finished
within 15 days completely.
Application Range
It is mainly used in municipal services,roads,railways,water conservancy,environmental protection and industrial and
civil buildings in the construction of underground seepage control.
Unlike the membrane,its unique role include:
1. It is used in the landfill sites under the primary geomembrane lining.
2. It is used in the landfill under the sub-lining of the geomembrane.
3. Under the landfill geomembrane and below the clay layer,that is the lining of three components.
4. Under the geomembrane in the landfill cover layer.
5. Adjacent with the geomembrane in the vertical cut-off water wall.
6. It is used on the geomembrane to prevent the coarse-grained materials puncturing the geomembrane.
7. It is used as the second layer of underground water wells linging.
