Speaking of the classification of geotextiles, many people naturally think of filament geotextiles, short fiber needle punched geotextiles, woven geotextiles and so on. Of course, these are classified according to the way of production and processing, but how to classify them according to the functional attributes?

1. Drainage inverted filter Geotextile

The main function of drainage filter geotextile in the project is to keep the particles of soil layer from losing when the gas and liquid pass through the geotextile, so as to ensure the stability of the building. In some special cases, such geotextile will also play the role of drainage channel. There are many applications of geotextile, such as blind drainage ditch, slope protection and filter layer behind retaining wall.

2. Wrapped Geotextile

The wrapped geotextile mainly exists as the inclusion, that is, some loose soil or loose sand and some crushed stone are wrapped to form a certain volume or shape of block, and then applied to the slope protection or erosion engineering. There are many corresponding products of wrapped geotextile, such as geobags, geomembrane bags, geotube bags and so on.

3. Isolated Geotextile

As the name implies, the isolation geotextile mainly plays the role of isolation, that is, it is laid between two different media to prevent the two media from mixing together. The isolation type geotextile is mainly used for isolation between different building materials, or it is laid on the surface of soft soil to prevent the drainage cushion above it from being blocked.

4. Reinforced Geotextile

Reinforced geotextile has a good tensile strength, which is mainly buried in the land. Through certain interaction, it can ensure the stability of the land and prevent soil movement and loss. The common reinforced geotextile is mainly used in the processing of soft foundation cushion or reinforced soil structure.
