Geosynthetic Clay Liner 4 Layer Geosynthetic Clay Liner Sodium Bentonite Blanket
Geosynthetic Clay Liner 4 Layer Geosynthetic Clay Liner Sodium Bentonite Blanket
Geosynthetic Clay Liner Description
Geosynthetic clay liner with PE Geomembrane 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 geotextile).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.
Sodium bentonite granule consists of natural clay inorganic mineral materials processed with high expansion and high water absorption capacity, low permeability when wet performance, mainly for waterproofing.
Geosynthetic Clay Liner Property
1. Sweel when meet water
2. Long time waterproofing and friendly to environment
3. Separation, reinforcement, protection, filtration and easy for construction
Geosynthetic Clay Liner Application
1. Municipal project, subway, undergroung and roof waterproofing
2. Landfill, waste water treatment, industrial waste
3. Waterproofing and reinforcement in water conservancy, river, lake and dam
4. Artificial lake, golf courst and fish pond
5. Petrifaction and mineral waterproofing
