I.high-quality materials, excellent performance
Our composite geomembranes are made of high-quality polymer materials, featuring high strength, high durability, high waterproofness, and high impermeability. These materials are carefully selected and tested to ensure excellent performance under various soil conditions and hydrological conditions. We are aware of the importance of material quality for engineering, so we insist on using high-quality materials that meet international standards. Composite geomembrane is an engineering material composed of geomembrane and other geotechnical materials, which has various advantages and wide application fields. Here are some introductions about composite geomembrane：

1. Definition and composition: Composite geomembranes are engineering materials composed of a geosynthetic material (such as geotextile or geogrid) combined with a geomembrane. They are classified into one-fabric one-film and two-fabric one-film. They utilize the advantages of different materials to improve soil stability, waterproofness, impermeability, and durability.

2. Manufacturing process: The manufacturing process of composite geomembranes involves combining different materials to achieve the desired performance and effect. Common composite methods include pressure-sensitive composite, coating composite, hot pressing composite, etc. The commonly used processes in our company are pressure-sensitive composite and hot pressing composite. The specific process is shown in the following figure:

3. Performance characteristics: Composite geomembranes have a variety of excellent performance characteristics, including high strength, high durability, high waterproofness, and high impermeability. In addition, it also has the advantages of light weight, ease of construction, and environmental protection.

4. Advantages: composite geomembranes have many advantages, such as improving engineering efficiency, reducing costs, and extending the life of the project.

II.The main specifications of composite geomembranes are as follows:

1. Material: The raw material of composite geomembrane is mostly polyethylene.

2. Thickness: The thickness of composite geomembranes varies depending on engineering requirements and material types. Generally, the thickness ranges from 2mm to 6mm, depending on the required load-bearing capacity and durability.

3. Width: The width of composite geomembranes is also designed according to the needs of the project. The common width is 3m-6m, which can be selected according to the construction conditions and actual needs.

The specific specifications are as follows:
