Geotextiles

Geotextile is a kind of new building decoration material, which is used to manipulate earth and rock, protect slope and so on in engineering construction or pollution control project. Generally, it is composed of polyester cloth or polypropylene cloth, and its making method can be divided into needling, spinning, nonwovens or thermal bonding according to its application. Geotextile is very firm and durable, and has a very good water absorption, can let water through, in addition to the soil layer and rock layer particles left, so as to achieve the fixed effect and avoid precipitation corrosion. Geotextile is usually part or all of them buried in geotechnical engineering, so it is very important to ensure its wear resistance and tear resistance.


One of the functions of geotextile is to worry, which is usually used to control environmental pollution. For example, in the construction site, countless soil and dust are mixed during the work. When it's rainy or when there's a drain here, the soil layer can get into the ditch and block it. The geotextile can be installed around the construction site to avoid the outflow of water and soil in the soil layer. When geotextile is used for reservoir and coal roadway regulation, it can also be used as a filter.


Geotextile can also be used to separate different rock layers and soil texture, and structural reinforcement. Such as embankment or revetment projects, the soil layer and rock layer will decline in work, or in extreme weather trend. We can use geotextile to carry out safety protection for river embankment and slope protection. It can be fixed with the plant flower system to protect the slope, showing stable maintenance.


In some applications, geotextile will be used for environmental health and safety. For example, the environmental protection bureau wants to avoid the corrosion of soil layer by running water. Geotextile can also be used to inhibit the growth and development of weeds and help maintain the subgrade and other natural environment.
