Usage
Geosynthetic clay liner is a kind of anti leakage earthwork synthetic material that applicable for artificial lake water, garbage landfill, underground garage, roof garden, pool, oil depot and chemicals yard and other places. As geosynthetic clay liner manufacturer known, they are widely used in these following area:
- Landfill Impermeable Layer
- Waterproofing
- Vertical Impermeable Layer
- Canal, Dam, Reservoir
- Ground Water Protection
Geosynthetic clay liner manufacturer is also known as sodium bentonite composite waterproof pad manufacturer. Geosynthetic clay liner is to create a strongly swelling sodium bentonite filling inside between special composite geotextile and fleece. The waterproof bentonite cushion made with the acupuncture method can form many small fiber spaces. This prevents the bentonite particles from flowing in one direction, when it hits water, it can form a uniform, high-density, colloidal waterproof layer on the base, effectively preventing water leakage, the geosynthetic clay lining is suitable for artificial seawater, landfill, underground car park, roof garden, swimming pool, oil tank and chemistry area.

Practical Applications
Geosynthetic clay liner can be used for pond, it is suitable for drilling lining and applicable for landfill. Geosynthetic clay liner is mainly used for waterproofing construction, it can also be used for artificial lake.
Waterproofing principle
The mineralogical name of bentonite is montmorillonite. Natural bentonite is divided into two main categories according to its chemical composition: sodium-based and calcium-based. Bentonite has the property of swelling when exposed to water. Generally speaking, when calcium-based bentonite expands, its expansion is only about three times of its own volume. However, when sodium-based bentonite meets water, it can absorb 5 times its own weight of water and expand to more than 15-17 times its volume. Locking sodium bentonite in the middle of two layers of synthetic materials can play a protective and reinforcing role. And make the geosynthetic clay liner has a certain overall shear strength.
Construction method and precautions
- When laying sodium-based bentonite composite waterproof mat, usually lay the non-woven fabric (white) facing up, woven fabric (black) facing down, or according to the design requirements, engineering requirements to lay.
- When laying, should avoid rainy days, such as a sudden encounter with rain, should stop laying, and covered with plastic film to prevent rainwater intrusion, hydration.
- Sodium bentonite composite waterproof mat construction should first confirm the direction of water flow, laying along the direction of water flow, so that the upstream waterproof mat pressed on the downstream waterproof mat.
- In the slope and slope construction, sodium-based bentonite composite waterproofing mat length direction should be perpendicular to the bottom surface.
- The bottom laying should be parallel lap, taking into account the foundation of the sinking deformation laying, can be wrinkled at the bottom, appropriate relaxation and tight to the ground.
- When laying, it can be used mechanically or manually. Mechanical laying can take thick-walled iron pipe or iron rod into the core of the roll. One side is pulled apart, fixed, suspended in midair, open and flat.
- In construction, if the sodium-based bentonite composite waterproofing mat needs to be cut, only a knife can be cut freely as needed.
- When laying, it is strictly forbidden to put fire or cigarettes on any side of the sodium-based bentonite composite waterproofing mat.
- When laying, if the sodium bentonite composite waterproofing mat is broken, you should use a waterproofing mat that is 300 mm larger than around the broken area to cover, and then fixed.

Geosynthetic Clay Liner Manufacturer FAQ
Geosynthetic clay liners are widely used in artificial lakes, roof gardens, swimming pools, landfills, oil depots and chemical dumps. We at Huisen, the leading geosynthetic clay liner manufacturer, are often asked various questions about geosynthetic clay liners. Now, we have listed below the questions frequently asked by our customers for your reference when purchasing. If you have any questions, you can also contact us directly and we will be happy to receive your inquiries.
Geosynthetic clay liners (GCL) are an established sealant in the geo-environmental industry. They are used in landfill applications as caps and base liners, as secondary containment for fuel storage facilities, as well as in various other containment structures such as dams, canals ,rivers and lakes.
Sodium Bentonite Clay
Geosynthetic Clay Liner (GCL) are composite materials that combine outer layers of geotextile with a sodium bentonite clay core with low permeability. Bentonite is a natural sealant that acts (hydrates) on contact with water.
Geosynthetic clay liners (or GCL) represent the newest subset of geosynthetic materials. They are factory-made rolls of thin layers of bentonite clay that are embedded between two geotextiles or bonded with a geomembrane. Structural integrity is maintained through stamping, sewing, or physical bonding.
How do I install a geosynthetic clay liner?
Huisen now tells you from the perspective of a geosynthetic clay liner manufacturer that the installation of a geosynthetic clay liner requires the following three steps.
Step 1 – Excavate the area for the liner. The excavated area should be at least 12 inches deeper than the finished grade.
Step 2 – Prepare the area for the installation of the liner. Make sure the subgrade is free of any rocks and debris.
Step 3 – Install the geosynthetic clay liner.
What makes GCL different from other geosynthetic products is that it incorporates a woven geotextile for dimensional stability and is reinforced for increased internal shear strength. Huisen GCL offers an array of different features for applications requiring a wide range of load and slope conditions in mining, landfills and pond projects.
Bentonite clay contains natural minerals like calcium, magnesium, and iron that can provide additional benefits. Bentonite clay is formed from volcanic ash. It takes its name from Fort Benton, Wyoming, where it is found in large numbers.
