One of the largest manufacturer of Needle Punched Nonwoven Geotextile for Highway Construction with advanced equipment, big production capacity and excellent quality.
Over the past decade a greater emphasis has been placed on the development and manufacturing of geosynthetic textiles. While the geosynthetics industry is comparatively new, it has already created products with applications in a wide range of industries including geotechnical, transportation, hydraulic, embankment management, and mining. In many cases, a single geosynthetic textile can solve or improve multiple civil engineering problems simultaneously.
The first example of a geosynthetic textile application is the use of a prefabricated pocket style vertical drain made from a nonwoven filter jacket specialized as a PVD filter material. The purpose of this product was to reduce the time needed for construction by quickly discharging water in the ground which speeds up the soil consolidation process. Overall, it proved to reduce construction time and speed up the consolidation of soft ground in a variety of different situations including road construction, the development of building sites, construction of gas and oil storage facilities, and bank revetment.
The second example of how geosynthetic textiles can provide solutions to civil engineering problems is the polyester woven geotextile mat. It is created from a high tenacity polyester filament which is highly dense. This particular geosynthetic textile has been used to reinforce soft ground and embankments, separate layers of sand and soft ground, prevent the uneven settlement of soft ground, and securing a safe path of travel for heavy equipment across soft ground.
The third example is a silt curtain or fence created by geosynthetic textiles. A silt curtain is installed in the water to prevent the spread of environmentally dangerous contaminants. These contaminants often result from coastal and Riverside construction projects although it can also be used in the event of an open water spill or leak. It has been shown effective at preventing the spread of fine soil and sand induced by construction. It can also prevent the contamination of the nearby seaports and help preserve sea farming and area beaches.
The fourth and final example of geosynthetic textiles assisting with civil engineering problems is the polyester needle punched nonwoven geotextile. It is typically made of continuous filament fiber to promote fast drainage and filtration. It has been used to help prevent landslides, control erosion on banks, protect waterproof layers in landfills, prevent road tracking, and protect waterproof sheets and tunnels.
There is no doubt geosynthetic textiles will continue to play a greater role in finding workable solutions to civil engineering problems across the globe. As their production continues to scale, prices will decrease which will lead to an increase in availability as well as further research and development.
- Q: How do geotextiles improve the performance of slopes?
- Geotextiles improve the performance of slopes by providing erosion control, stabilization, and reinforcement. These synthetic fabrics are installed between the soil layers of the slope, acting as a barrier to prevent soil movement and erosion caused by water flow or wind. Geotextiles also enhance the overall stability of the slope by improving soil drainage, reducing pore water pressure, and increasing soil strength.
- Q: How do geotextiles help in stabilizing railroad tracks?
- Geotextiles help in stabilizing railroad tracks by providing reinforcement and separation between the subgrade and the ballast layer. They prevent the mixing of fine particles from the subgrade with the ballast, thereby maintaining its integrity and preventing track settlement. Geotextiles also distribute the load evenly, reducing the stress on the subgrade and improving track stability and longevity.
- Q: What are the different geotextile testing methods?

Additionally, geotextiles also help in promoting vegetation growth by retaining moisture and providing a favorable environment for plant root development, further strengthening the soil and reducing erosion.
- Q: What are the factors to consider when designing geotextile tubes for dewatering?
- When designing geotextile tubes for dewatering, there are several factors to consider. Firstly, the type and characteristics of the sediment or sludge being dewatered should be evaluated, including its composition, particle size distribution, and consolidation properties. This information will help determine the appropriate geotextile fabric and pore size required to effectively retain the solids while allowing water to drain. Secondly, the hydraulic loading conditions need to be considered. The flow rate, pressure, and duration of the dewatering process will influence the required strength and permeability of the geotextile tubes. Adequate strength is crucial to withstand the hydraulic forces and prevent structural failure. Additionally, the site conditions and environmental factors should be taken into account. The stability of the ground where the geotextile tubes will be placed, as well as any potential erosion or slope stability issues, should be thoroughly analyzed. The project location, climate, and potential impact on surrounding ecosystems should also be considered to ensure the chosen design is sustainable and minimizes any adverse effects. Lastly, the cost-effectiveness and practicality of the design should be evaluated. Factors such as the availability and cost of materials, installation methods, and maintenance requirements should be considered to optimize the overall dewatering process. Overall, designing geotextile tubes for dewatering requires a comprehensive assessment of sediment characteristics, hydraulic loading conditions, site conditions, and cost-effectiveness to ensure a successful and efficient dewatering solution.
- Q: How do geotextiles affect soil temperature?
- Geotextiles can have an impact on soil temperature by acting as an insulating layer. They can help regulate soil temperature by reducing heat transfer between the soil and the atmosphere. This insulation effect can prevent soil from overheating in hot climates or help retain warmth in colder regions. Additionally, geotextiles can also minimize temperature fluctuations in the soil, providing a more stable environment for plant growth.
- Q: What are the factors to consider when selecting geotextiles for coastal protection projects?
- When selecting geotextiles for coastal protection projects, several factors need to be considered. These include the strength and durability of the geotextile, its resistance to UV radiation and chemicals, its ability to filter and drain water, its compatibility with the existing soil and vegetation, its installation and maintenance requirements, and its cost-effectiveness. Additionally, the specific environmental conditions and project goals should also be taken into account.
