How to judge the quality of geotextile?

Material selection: High-quality geotextiles are usually made of high-strength, durable polymer materials such as polypropylene (PP) or polyester (PET). These materials have good tensile, tear and chemical resistance. Therefore, you can check the material description and certification of geotextile products to understand the type and quality of materials used.

Specifications and characteristics: The specifications and characteristics of geotextiles are also important indicators for evaluating quality. Common specifications include weight, thickness, width and mesh size, etc. Proper weight and thickness are generally related to the strength and durability of the geotextile. At the same time, characteristics such as water permeability, chemical resistance, and UV resistance should also be considered when selecting geotextiles to ensure that they meet specific project requirements.

Physical property testing: The physical properties of geotextiles have a great influence on its quality and reliability. Common physical property tests include tensile strength, tear strength, elongation at break, bending resistance, etc. Suppliers can be required to provide relevant test reports or certifications to understand whether the physical properties of the geotextile meet the required standards.

Manufacturing process and certification: Knowing the supplier’s manufacturing process and certification can also help in assessing the quality of the geotextile. Suppliers should follow relevant international or industry standards, such as ISO certification, to ensure product quality and reliability.

Project experience and word of mouth: Inquiring about the supplier’s project experience and word of mouth can also provide clues to evaluate the quality of geotextiles. A supplier’s experience and reputation can reflect its product quality and customer satisfaction.

After-sales service and warranty: Knowing whether the supplier provides good after-sales service and product warranty is also an important factor in evaluating the quality of geotextiles. High-quality suppliers usually have technical support and timely after-sales service to solve problems and provide assistance.

In conclusion, when choosing geotextiles, cooperating with reliable suppliers and following relevant standards and specifications, while referring to the advice of professional engineers and designers, can improve the accuracy and reliability of judging the quality of geotextiles.
