In the past, civil engineering construction encountered that the soil is not suitable for construction, usually they will solve this problem by replacing the soil or by deep foundation construction method to avoid the construction of difficult soil. This makes the project cost higher and more difficult to constructed. Therefore, it is an urgent demand to find a material that can improve the construction conditions and the quality of the project. For a long time, due to the scarcity of land, the transformation of old urban infrastructure, the improvement of infrastructure quality and the demand of environmental governance, geosynthetics came into being. Now, we usually call it geotextile or non woven fabric. In the past 25 years, the area of application has rapidly expanded to civil, geotechnical, environmental and coastal areas and water conservancy projects in almost all areas of civil engineering, so it becomes an indispensable new geotextile material.
