GCL liner, also known as Geosynthetic Clay Liner, is a high-performance needle-punched environmentally friendly reinforced composite that combines two durable geotextile outer layers with a uniform core of natural sodium bentonite to form a hydraulic barrier. Bentonite waterproofing blankets are usually held together mechanically by needling, stitching or chemical adhesives. Bentonite waterproofing blankets are widely used as an alternative to compacted clay liners. After hydration, the bentonite in the bentonite waterproof blanket can self-swell to form a low-permeability clay layer that has hydraulic protection equivalent to several feet of compacted clay when hydrated under confining loads. Bentonite clay waterproofing blankets can provide about the same hydraulic protection as compacted clay. Excellent tensile and peel strength properties make GCL liner ideal for composite liner systems, composite base liners for landfills and backfill anti-seepage liners, among others.

Why Chose GEOSINCERE GCL Liner for Irrigation Pond Project
Geosincere is the leading geosynthetics manufacturer and supplier. We offer wholsale geosynthetics and installation service. As an arid country in Argentina, irrigation ponds are one of the important facilities to ensure agricultural production. There are a large number of irrigation ponds there. According to statistics, there are more than 1,700 irrigation ponds in the country, with a total area of more than 600,000 hectares, providing sufficient agricultural production. Irrigation water source. Argentina’s irrigation ponds are distributed throughout the country, mainly in the valleys and plateaus of the northwest and central regions. The climate in these areas is dry and water resources are scarce, but they have abundant summer rainfall, so the waste and loss of water resources must be solved in the construction of irrigation ponds.
Soluton of Geosynthetic Clay Liners for Irrigation Pond Project in Argentina
The GCL Liner made by acupuncture can form many small fiber spaces, because the bentonite particles cannot flow in one direction, and form a uniform high-density gel waterproof layer in the pad when it encounters water. It is used in the anti-seepage project of irrigation ponds in Argentina The application of GCL Liner effectively solves the problem of water resource waste and loss. Its excellent anti-seepage performance and other advantages meet the requirements of irrigation projects, and can improve the efficiency of water resource utilization and the benefits of agricultural production. Ensure the stable supply of water resources and improve the irrigation effect.
Benefits of GCL Liner Used in Argentina Irrigation Pond Project
1. Prevent water leakage:
Irrigation ponds are usually earth dams made of materials such as earth and rocks. These materials usually have a certain degree of permeability, which can easily lead to leakage and waste of irrigation water. The use of Geosynthetic Clay Liner can form a waterproof layer on the surface of the earth dam, effectively preventing water leakage and waste of water resources.
2. Prevent land desertification:
In arid areas, the irrigation water of the irrigation pond is usually the only water source on the land, and the vegetation and soil on the land are easily affected by the evaporation and infiltration of water, resulting in land desertification. The use of Geosynthetic Clay Liner can effectively reduce the evaporation and infiltration of water, maintain the humidity of the land, and thus slow down the process of land desertification.
3. Improve irrigation efficiency:
Using GCL Liner can effectively prevent water waste and leakage, improve irrigation efficiency, reduce irrigation water usage, reduce irrigation costs, and improve agricultural production efficiency.
4. Enhance the stability of the irrigation pool:
Using GCL Liner can enhance the stability of the irrigation pool, reduce the scour and erosion of the pool bottom and pool dam, and improve the service life and safety of the irrigation pool.
Which Texture Conditions Should GCL Liner be Used?
GCL Liner is suitable for a variety of texture conditions, the following are some texture conditions suitable for waterproof blankets:
1. Areas with high groundwater table:
In areas with high groundwater table, the ground is vulnerable to groundwater infiltration and erosion. Using GCL Liner can effectively prevent groundwater infiltration and protect the stability of the ground.
2. Areas with soft soil:
In areas with soft soil, the ground is easily affected by soil erosion and settlement. Using GCL Liner can effectively prevent soil erosion and foundation settlement and protect the stability of the ground.
3. Areas with large slopes:
In areas with large slopes, the ground is easily affected by water erosion. Using GCL Liner can effectively prevent water erosion and protect the stability of the ground.
4. Waterproof treatment of underground buildings:
In the waterproof treatment of underground buildings, the use of GCL Liner can effectively prevent groundwater penetration and leakage, and protect the structure and equipment of buildings.
In short, Geosynthetic Clay Liner is suitable for a variety of texture conditions, can effectively prevent water penetration and erosion, and protect the stability and safety of the ground and buildings.
GCL Liner Installation Method
GCL Liner is a commonly used waterproof material, and its construction technology has an important impact on waterproof effect and service life. The following are common construction techniques for GCL Liner:
1. Preparation before laying:
Before laying Geosynthetic Clay Liner, the base layer needs to be cleaned and treated to ensure that the base layer is flat, clean, and free of loose substances and sharp objects. At the same time, the GCL Liner needs to be inspected to ensure that the quality and specifications of the material meet the construction requirements.
2. Laying of GCL Liner:
Lay the GCL Liner on the base layer according to the design requirements, and pay attention to ensure that the waterproof blanket is flat, tight and wrinkle-free. In the laying of the waterproof blanket, the joints of the blanket need to be processed by welding or bonding to ensure the waterproof effect of the entire waterproof system.
3. Compaction and covering of GCL Liner:
After the waterproof blanket is laid, it needs to be compacted to tightly combine the waterproof blanket with the base layer. An overlay is then added to protect the waterproof blanket from damage and also improve the compression resistance of the waterproofing system.
4. Construction quality control:
In the construction process of Geosynthetic Clay Liner, it is necessary to strictly control the construction quality to ensure the waterproof effect and service life. For example, it is necessary to pay attention to the welding quality of the waterproof blanket, the treatment of the seams, the compaction quality, the thickness and quality of the covering layer and other details.
Summary
GCL Liner is a widely used waterproof material, suitable for a variety of engineering projects, such as water conservancy engineering, road engineering, construction engineering, water treatment engineering, landfill, mining engineering, etc., can effectively prevent water penetration and erosion , to protect the stability and security of the project.
