Although the development time of geotextile is not long, the development speed is really amazing. The geotextile originated in the United States and spread to other countries gradually later. At first, the geotextile was only used in coastal engineering, and then gradually expanded to other fields. Nowadays, geotextiles are widely used in both developing and developed countries. There are four main fields of geotextile application:

1. Water conservancy project: including the construction of coastline, dyke and reservoir in China, geotextile is needed for reinforcement, reinforcement and drainage. It is estimated that there will be more than ten tons of Geotextile for river renovation.

2. Construction Engineering: it is mainly the development of real estate, such as the reinforcement of foundation, the waterproof of roof and roof, etc., which need to use geotextile. Now the real estate industry is booming, and it is estimated that the required geotextile is more than 200 million cubic meters.

3. Environmental Engineering: now people's awareness of environmental protection is gradually increasing. Geotextiles are used in many places that will create an image of the environment, such as the impervious geotextiles required by the landfill, the dust-proof geotextiles required by the poor air quality, and so on.

4. Others: geotextiles can also be applied to many environments that are not well classified, such as the mineral and metallurgical industry, mechanical equipment, etc.

The main application fields of geotextile are introduced above.
