Bentonite Waterproof Pad (gcl)

Geosynthetic Clay Liner for Basement

 

 

Product Introduction

 

Geosynthetic clay liner is composed of high dilatability of sodium base bentonite filling between the special composite geotextile 

and nonwoven fabric, made by the method of acupuncture or suture composite impervious materialUse acupuncture into 

geosynthetic clay liner can form many small fiber space, make the bentonite particles can't flow in one direction, when under the 

influence of water within the mat forming uniform density of colloidal waterproof layer, prevent the leakage of water. 

For different projects,it can combine HDPE liner for better waterproof.

 

Bentonite has the expansion of the water characteristicsGeneral calcium base bentonite expands, its expansion is only about 3 times 

their own size; And sodium base bentonite adsorption 5 times its own weight of water in case of water, Volume expansion to the 

original 15 to 17 times aboveLock sodium base bentonite in the middle of the two layers of geosynthetic materials, protecting 

and strengthening the role of, Make the GCL has a certain overall shear strength.

GCL Feature:

 

 

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 10-11 m/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.

GCL Application:

 

Application: Suitable for municipal (landfill), water conservancy, environmental protection, artificial lake, 

and building underground waterproof, seepage control engineering.
