GCL Geosynthetic Clay Liner
China GCL geosynthetic clay liner manufacturers supply high quality&factory price GCL geosynthetic clay liner if you want to wholesale high quality&factory price GCL geosynthetic clay liner, welcome to consult wholesale GCL geosynthetic clay liner for sale. Natural sodium bentonite waterproof blanket (wholesale GCL geosynthetic clay liner for sale) is referred to as high quality GCL geosynthetic clay liner for sale, which is a new type of environmental protection composite waterproof and impermeable material. High quality GCL geosynthetic clay liner for sale fills the bentonite particles between the spun geotextiles and the non-woven geotextiles, and combines the upper nonwoven fibers through the bentonite particles, through special technology and equipment, with needling method on the lower fabric. At the same time, according to the needs of the project, a layer of HDPE film (high density polyethylene film) can be bonded on the waterproof blanket to adapt to the laying of the special environment, so as to achieve the dual waterproof and seepage-proof effect.
Features of GCL Geosynthetic Clay Liner
GCL geosynthetic clay liner factory price produced by the China high quality GCL geosynthetic clay liner manufacturers has stable overall performance, high tensile and shear strength. The bentonite particles in the interlayer belong to inorganic materials. They are not aging and deteriorating. When the water absorption is highly expanded, they can form an impermeable gel. The permeability coefficient is 5*10-11, m/s. At the same time, the bentonite particles in the waterproof blanket do not flow in the same direction. They can form a uniform waterproof layer in the whole range and have excellent permanence. The durable waterproof and seepage-proof function is widely applied to waterproof and seepage-proof projects in the metro, tunnel, landfill, airport, water conservancy, artificial lake, golf course, and other fields. It is a new natural, green and environmental waterproof material.
1. The compactness
Sodium bentonite forms high-density diaphragm in water pressure state, and when the thickness is about 3mm, its permeability is & * 10nm/SEC below, which is equivalent to the density of 30cm clay of 100 times the thickness and has a strong self-retaining property.
2. Permanent waterproof performance
Because sodium bentonite is a natural inorganic material, even after a long time or changes in the surrounding environment, there will be no aging or corrosion phenomenon, so the waterproof performance is lasting.
3. The installation is simple and the installation period is short
Compared with other waterproof materials, the construction is relatively simple and does not require heating and paste. Only bentonite powder and nails, washers, etc. are used for connection and fixation. No special inspection is required after construction and it is easy to repair if waterproofing defects are found. high quality GCL geosynthetic clay liner for sale has the shortest construction period among the existing waterproof materials.
4. Not affected by temperature
It doesn’t break in cold weather.
5. Integration of waterproof materials and objects
When sodium bentonite meets water, it has a 20-28 times expansion capacity. Even if the concrete structure vibrates and subsidence occurs, bentonite in wholesale GCL geosynthetic clay liner factory price can repair cracks on the concrete surface within 2mm.
6. Green environmental protection
Bentonite is a natural inorganic material, harmless and non-toxic to the human body, has no special impact on the environment, and has good environmental protection performance.

Application of GCL Geosynthetic Clay Liner
Bentonite waterproof blanket, High quality GCL geosynthetic clay liner factory price can be widely used in municipal, highway, railway, water conservancy, environmental protection, and underground waterproof engineering in industrial and civil buildings. Anti-seepage engineering of landfill liner system, reservoir and diversion canal. It is suitable for external waterproofing of various underground structures and underground buildings and can replace the cement mortar waterproofing layer, paint waterproofing layer and other waterproofing layers in underground engineering waterproofing. Bentonite waterproof blanket (wholesale GCL geosynthetic clay liner factory price produced by the China GCL geosynthetic clay liner manufacturers) has high mechanical properties, but it does not have high tensile strain.
It will increase its permeability and is an irreplaceable waterproof and impermeable material in modern geotechnical engineering.
