(GCL) Geosynthetic Cay Liners 4500GSM --6500GSM

Product Description

(GCL) Geosynthetic Cay Liners

Sodium bentonite waterproofing blanket mat Geosynthetic Clay Liner GCL for waterproofing Geosynthetic Clay Liners 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. For different projects,Geomembrane Geosynthetic Clay Linercan combine HDPE liner for better waterproof. 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. The excellent properties of tensile and peel strength make the products ideal for many projects.gardens, building waterproof.
Sodium bentonite waterproof blanket GCL

Part one:  Description of GCL waterproof blanket 

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.

Part Three: The Application of GCL
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.

Brief Introduction of Dimple Drainage Board
Drainage Board adopt high-density polyethylene as raw material, using high pressure injection molding process
to suppress a hole-shaped lump, with three-dimensional space and certain support height. It is popularly
applied in roof greening, subway tunnels, water reservoir seepage, vertical green and many other areas.
Features
Drainage board has the special structure, which can quickly and effectively derived rain and greatly reduce or even eliminate the waterproof layer of hydrostatic pressure, also can achieve active waterproof effect through this initiative guide water principle. Pondage and drainage plate material itself is a kind of very good waterproof materials. By using reliable down slope of overlapped method, it is to become a kind of very good auxiliary waterproof material. Pondage and drainage plate can effectively reduce the indoor noise. Drainage shielding panels have very good ventilation moisture proof effect to use on the ground or metope.
The plastic storage and drainage plate is a type of green roof systems which are drained by a special molding plastic sheets. Water is retained within dimple on the upper sides of the drainage plates; excess water spills over the edges of the plates and is carried off the roof.


The plastic storage and drainage plates are made from HDPE(high-density polyethylene), using high pressure to inject plastic to form hole-lump-shaped shell, with stereo space and support level; in the top of the shell, covering with non-woven as filtering level for water percolation, water storage and water drainage.
 Product Feature
Compactness: sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm, its permeability is & x 10 m/SEC 11 below, equivalent to 100 times the compactness of 30 cm thickness of clay, have very strong since the water retention performance.
Permanent waterproof performance: 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.
Construction simple and short time limit: 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.
Integration: sodium base bentonite under water, the swelling capacity of 20~28 times, even if the concrete structure vibration and settlement, within the GCL bentonite can also repair the crack on the surface of the concrete within 2 mm.
Green: bentonite as natural inorganic material, non-toxic harmless to human body, no special effects to the environment, have good environmental performance.
