Jingwei® Bentonite Geosynthetic Clay Liner

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 non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven).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.

Jingwei® Technical Parameter

Features : 

1.The permanent waterproof

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.

2. Compactibility

Sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm, 

its permeability is 5 x 10-11m/SEC below, equivalent to 100 times the compactness of 30 cm thickness of clay, 

have very strong since the water retention performance. 

3.Not affected by temperature

In cold climates will not brittle fracture.

4.Environmental protection 

Bentonite as natural inorganic material, non-toxic harmless to human body, no special effects to the environment, 

have good environmental performance.

5.Simple and short time of construction

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.
