Wide application 4500g GCL cost geosynthetic clay liners for dam and landfills grout
Product Description
Natural sodium bentonite geosynthetic clay liner Product Introduction;
The GCL is punched together with non-woven geotextile, woven geotextile and bentonite. Width of the geosynthetic clay liners can be up to 6m and length of 60m. The middle level is bentonite grains, which are carefully selected crude and filled in between the two levels after special processing. The bentonite grain in GCL made by this method does not flow in a fixed direction. It distributes evenly and forms waterproof layer, owning excellent waterproof effect. This GCL is a kind of new green waterproof materials, which are widely applied in many waterproof construction projects. GCL can be applied separately, or combined with high density polyethylene (HDPE).
GCL sodium bentonite geosynthetic clay liner is a new type of geosynthetic material, and it can be divided into needle-punctured GCL(GCL-NP) and needle-punctured coated GCL(GCL-OF). GCL is a kind of bentonite seepage-proofing mat needle-punctured through filling sodium bentonite between woven geotextile and non-woven geotextile. Among which tiny fiber spaces can be formed to prevent bentonite particles to move to a direction. It can form glue-type water-proofing layer to prevent water leakage. Woven geotextile of 120g/㎡ and non-woven geotextile of 220g/㎡ are applied in this kind of GCL.Mass per unit of GCL sodium bentonite clay liner can be divided into: 4000g/㎡, 4500g/㎡, 5000g/㎡, 5500g/㎡, etc. The length of the product is 30m, and the width is 6m.

Application
Installation Methods:
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
Preparation before paving the GCLs:
1.Drawing the GCLs paving order
2.Examining the GCLs appearance quality
3.The construction of GCLs should be processed under the weather with no rain and snow
GCLs paving:
1.When paving the GCLs, it can use the machine and also the manpower.
2.Paving the GCLs according to the stated order and way.
3.Paving the GCLs, seaming overlapping between mat and mat should be staggered.
4.There should not be sand and soil, hydrocele and so on impurity, to avoid affecting on the
overlappingquality.
5.To avoid the GCLs gliding, had best to fix it with nails when installing in vertical and
bevel. Such asdrawing
6.Both sides of the GCLs are geotextile and woven geotextile, when paving, the geotextile
should be nextto the water
7.When paving, examine the GCLs appearance at any moment

Backfill:
1.GCLs(bentonite clay liner )paved must be backfilled on the day.
2.The sand or the sifted soil is the best choice, and the soil should not have impurity with
more than10mm.
3.The soil must be tamped every backfilling 50cm, and the degree of density should be more than
85%.
4.Pay attention to the GCLs when tamping, it can not be damaged.
5.When backfilling in the planar surface, the thickness should be 30cm at least.
