Geosynthetic clay liners (GCLs) Description:


Geosynthetic clay liners (GCLs) are high performance needle punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural

sodium bentonite clay to form a hydraulic barrier. Fibers from the nonwoven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile

(either a woven or nonwoven).when hydrated under a confining load, the bentonite swells to

form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay.



Geosynthetic clay liners (GCLs) Features:


1. Environment friendly

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

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.


5. Disposal of subgrades:

1. the subgrades must be tamped before paving the GCLs, the surface should be smooth. And it should not

have the obvious hollow space.

2. the surface should be dry.

3. the minimum angle of land surface exposed to the sun should be more than 30cm.

4. the construction of GCLs should be begin until checking out the foundation

6. Preparation before paving the GCLs
