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.

Applications:
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.
