That arises problems in many companies and individuals when it comes to purchasing geotextile and geomembrane. What is the difference of geomembrane vs geotextile? How to choose bwteen geomembrane and geotextile?
1.1 What Is A Geomembrane
A geomembrane, an exceptional waterproof and isolation material with unique attributes, is predominantly utilized in hydraulic engineering for a multitude of functions. It is primarily composed of high density polyethylene, with a thickness ranging from 0.3 mm to 30 mm. Geomembrane’s exceptional compressive strength enables it to withstand heavy loads without any deformation, a quality that is crucial in hydraulic engineering. Additionally, the material is highly resistant to high temperatures, ensuring its adaptability in diverse climates and weather conditions.
It is crucial to emphasize that the quality of smooth geomembrane HDPE Liner can vary depending on the manufacturing process and the quality of raw materials used during production. For hydraulic engineering applications, it is crucial that the geomembrane meets specific performance criteria, including a minimum density of 90 kg/m3, an extreme elongation rate of 300%, an anti-freeze property of -60°C, and a stabilization efficiency of not less than 2% of carbon black in polyethylene. The stability and resistance to environmental changes largely depend on these factors.

3 What is The Difference of Geomembrane vs Geotextile
3.1 Material and Manufacturing Process
Geomembranes liners are commonly manufactured using the extrusion method, utilizing high-density polyethylene (HDPE) material. This geomembrane manufacturing process results in a durable and impermeable membrane that is capable of withstanding environmental stresses. On the other hand, geotextiles are typically produced from polypropylene or polyester fibers. These fibers undergo weaving, needle punching, or heat bonding techniques to create a geo fabric with desired properties. The selection of materials and manufacturing techniques for geomembranes and geotextiles ensures their suitability for specific project requirements, providing effective solutions for environmental protection, soil stabilization, and water management.
3.2 Water Permeability
The geomembrane is impermeable to water, whereas geotextile fabric is water permeable. Geomembranes have excellent waterproof property and are widely used to prevent seepage, while geotextiles have good drainage and filtration properties. When we usually use them together. The They are classified into one fabric and one membrane, and two fabrics and one membrane, which have stronger reinforcement and anti-seepage performance.
Geotextiles serve as an effective filter, separating and reinforcing different materials while providing essential support and stability. Geotextiles are designed with a high permeable coefficient, which is typically 10 times greater than the soil’s permeability coefficient. This ensures efficient drainage and prevents the fine particles from being carried into the geotextile. As the geotextile filters the soil, it creates an artificial drainage layer, which traps the coarse particles and forms a protective layer. This layer is characterized by a high saturation coefficient, but its ability to retain fine particles is limited.
3.3 Different Functions in Practical Application
The primary function of geomembrane is to insulate groundwater and other pollutants, such as sewage and silt, in engineering projects, while preventing the penetration of soil particles, sand, and other materials. This ensures the stability and safety of the project. Geotextile, on the other hand, is mainly used for reinforcement and isolation in engineering applications, such as the construction of roads, levees, and other infrastructure. It is also employed for the decoration and protection of parks, golf courses, roofs, and other surfaces.
Both geomembranes and geotextiles have applications in various industries, including civil engineering, environmental protection, agriculture, mining, and more. The specific application depends on the project requirements and desired functions of the materials.
3 Conclusion
In conclusion, while geomembranes and geotextiles may sound similar as the important gepsynthetic material, their distinct compositions and functions make them indispensable in different applications within the realm of geosynthetics. By understanding their unique attributes, engineers and environmental professionals can harness the full potential of these materials, ensuring the success and longevity of their projects.
