How to Select the Right Geotextile?

-Clarify the project requirements

1.Project type and purpose: First, it is necessary to clarify what type of project the geotextile will be used for, such as water conservancy projects, highway projects, environmental projects, etc. Different projects have different performance requirements for geotextiles.
2.Specific application scenarios: Understand which specific part of the project the geotextile will be used for, such as dams, embankments, roadbeds, landfills, etc., in order to select the appropriate type of geotextile.
3.Service life and environmental conditions: Consider the service life of the project and the environmental conditions in which it is located, such as temperature, humidity, pH, etc., which will affect the performance and life of the geotextile.

-Determine the type of geotextile

1.Short-fiber needle-punched geotextile (also known as short-fiber geotextile): It has the characteristics of slow aging, filtration, repeated filtration, acid and alkali resistance, wear resistance, good flexibility, and simple construction. It is suitable for the maintenance, filtration, and reinforcement of roads, railways, dams, and hydraulic structures.
2.Filament spunbond needle-punched nonwoven geotextile (also known as filament geotextile): In addition to the characteristics of short-fiber geotextile, it also has a sealing (anti-seepage) function. It is mainly used for the protection and anti-seepage of water conservancy, dams, tunnels, and landfills.
3.Composite geotextile (also known as waterproof geotextile): It is made of a layer of geomembrane bonded to a layer of geotextile on the top and bottom. It has an anti-seepage effect and is suitable for the anti-seepage of artificial lakes, reservoirs, canals, and landscape lakes.
4.Woven geotextile: It uses polypropylene and propylene-ethylene flat wire as raw materials, has a specific weaving structure and performance, and can be customized according to engineering needs.

-Consider performance requirements

1.Tensile strength: ensure that the geotextile can withstand the tensile force in the project without breaking easily.
2.Elongation: measure the elongation ability of the geotextile under the action of external force, affecting the stability and durability of the project.
3.Permeability: select geotextiles with appropriate permeability according to the project needs to meet the requirements of drainage or anti-seepage.
4.Tear strength: evaluate the resistance of the geotextile when subjected to tearing force.
5.Thickness and unit area mass: these parameters directly affect the physical properties and cost of the geotextile.

-Evaluate cost and cost performance

Consider the cost and cost performance of the geotextile on the premise of meeting the project requirements. The prices of geotextiles of different specifications and materials are different, and they need to be reasonably selected according to the project budget and actual needs.

-Choose products from regular manufacturers

In order to ensure the quality and performance of geotextiles, it is recommended to choose products produced by regular manufacturers. Regular manufacturers usually have a complete quality management system and after-sales service system, and can provide products that meet relevant standards and requirements.

-Check the inspection report and quality certificate

When purchasing geotextiles, carefully check the product's factory inspection report and quality certificate. These documents can prove whether the product meets the relevant standards and requirements, and provide protection for the safety and stability of the project.

-Consider construction and maintenance

Finally, it is also necessary to consider the construction and maintenance of geotextiles. According to the needs of the project, the laying and connection methods of the geotextiles should be reasonably arranged to ensure that they can play the best effect. At the same time, during the use process, the maintenance and care of the geotextiles should be strengthened to extend their service life.
