Woven Fabric Geotextile
1.Good filtering performance：It can effectively intercept soil particles, allow water or gas to pass through, prevent soil erosion, and protect foundations and drainage systems in water conservancy, highway and other engineering projects.
2.Strong drainage capacity：There are many pores inside, which can quickly drain accumulated water, reduce the water level and pressure in the soil, and avoid damage to the project due to accumulated water.
3.Significant reinforcement effect：It can enhance the tensile strength and stability of soil, reduce soil deformation, and is commonly used in roadbed, dam and other engineering projects to improve the structural bearing capacity.
4.Outstanding protective effect：It can isolate different soil layers to avoid mixing with each other, while buffering external impacts and protecting soil or other structures from damage.

Product Application
Water conservancy engineering
In dam and channel construction, it can be used to filter soil particles in water flow to prevent the dam from being washed away; At the same time, it helps to drain the accumulated water around the dam or channel, reduce the impact of water pressure on the engineering structure, and enhance the stability of water conservancy facilities.
Highway and railway engineering
Laying in the roadbed can isolate different layers of soil and avoid mixing of roadbed materials; It can also enhance the bearing capacity of the roadbed, reduce road surface settlement, and discharge moisture from the roadbed, extending the service life of highways and railways.
Municipal Engineering
In projects such as sewage treatment plants and landfills, it can serve as a filtering layer to prevent impurities from clogging the drainage system; It can also serve as a protective measure, isolating landfill materials from surrounding soil and reducing pollution risks.
Agricultural Engineering
When used for irrigation channels in farmland, it can filter sediment in water, protect the channel from sedimentation, and discharge excess water, maintain suitable soil moisture, and promote crop growth.
Summary paragraph: Geotextiles play an important role in various engineering fields such as water conservancy, highways and railways, municipal engineering, agriculture, etc. due to their multiple functions of filtration, drainage, reinforcement, and protection. It can not only improve the stability and durability of engineering structures, but also reduce maintenance costs, making it an indispensable key material in various types of engineering construction.
