GCL Sodium Bentonite Liner Geosynthetic Clay Liners

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 material. Use 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 characteristics. General 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 above; Lock 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.

Geosynthetic Clay Liner

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.

Q: How are geotextile tubes used in shoreline restoration projects?: Geotextile tubes are used in shoreline restoration projects to create barriers or structures that help protect the shoreline from erosion caused by waves, tides, and storms. These tubes are often filled with sand or sediment and placed along the shoreline to form dunes or breakwaters, providing stability and preventing further erosion. Additionally, the geotextile material allows for water drainage while retaining the sediment, promoting natural vegetation growth and enhancing the overall ecological function of the shoreline.

Q: How do geogrids improve the load-bearing capacity of retaining walls?: Geogrids improve the load-bearing capacity of retaining walls by providing additional reinforcement and stability to the soil. They are installed within the layers of soil behind the wall, creating a strong and interconnected system that distributes the load more effectively. This prevents excessive movement and deformation of the soil, enhancing the overall strength and stability of the wall.

Q: Material in the civil engineering in what kind of position: Right now, there are many people to develop new materials, new structure system. Is also a very challenging field, worth exploring!

Q: How do geosynthetic liners prevent contamination in waste containment facilities?: Geosynthetic liners act as a barrier between the waste and the surrounding environment, preventing the contamination of soil, groundwater, and surface water. These liners are impermeable, meaning they do not allow liquids or pollutants to pass through them. This prevents the leaching of hazardous substances from the waste into the surrounding ecosystem, ensuring the protection of the environment and human health.

Q: What is the purpose of using earthwork products in construction?: The purpose of using earthwork products in construction is to shape and manipulate the earth's surface to create a stable foundation, provide drainage, control erosion, and achieve desired grades and slopes. These products, such as soil, gravel, and rocks, are used to build roads, embankments, foundations, and other infrastructure elements, ensuring the structural integrity and longevity of the construction project.

Q: How can geogrids be used in road construction projects?: Geogrids can be used in road construction projects by providing reinforcement and stabilization to the soil and aggregate layers, reducing the potential for settlement and rutting. They are typically placed between different layers of the road, such as subgrade and base courses, to improve the overall strength and durability of the pavement. Additionally, geogrids can help distribute the loads more evenly, enhance the load-bearing capacity, and extend the lifespan of the road.

Q: Can earthwork products be used in coastal restoration projects?: Yes, earthwork products can be used in coastal restoration projects. These products, such as sand, gravel, and soil, can be utilized to rebuild or enhance coastal areas, including beaches, dunes, and wetlands. These materials can help stabilize shorelines, protect against erosion, and create habitats for wildlife.

Q: How are earthwork products different from regular construction materials?: Earthwork products are different from regular construction materials because they are derived from natural sources such as soil, clay, and gravel, whereas regular construction materials are often manufactured or processed materials like concrete, steel, or bricks. Earthwork products are primarily used for shaping and modifying the terrain, such as grading, excavating, or filling, whereas regular construction materials are used for structural purposes, like building foundations, walls, or roofs.

Q: Are there any specific earthwork products available for drainage systems?: Yes, there are specific earthwork products available for drainage systems. Some common products include perforated pipes, drainage mats, geotextiles, and gravel. These products help to manage excess water, redirect it away from structures, and prevent soil erosion.

Q: Can earthwork products be used for soundproofing purposes?: Yes, earthwork products can be used for soundproofing purposes. Earthwork materials, such as soil, clay, or rocks, have natural sound absorption properties that can help reduce noise transmission. These materials can be used to create barriers or as fillers for walls, floors, or ceilings, effectively reducing sound transmission and improving sound insulation in buildings or outdoor spaces.
