Now, geotechnical materials have been used for many years in countless construction fields around the world. With Geosynthetics, roads, railways, sewers, dikes and ditches can be built more easily, with low costs, particularly for roads and railways, which can effectively reduce maintenance costs. In general, in the industrial textiles, geotechnical materials are the most mature.
Geogrid is widely used in the field of architecture, although we may not be unfamiliar with the grid, but there are many kinds of grids, such as fiberglass grille, steel plastic geogrid, plastic geogrid, etc. Although they all belong to the grid, but due to the different materials, their characteristics and functions will be a certain difference.
The development of Geosynthetics has been late in China, and the machine-woven geotextile has been applied to river and culvert works in the middle of the 60 's. In the early 80, Nonwovens began to be tested on railway engineering and Water conservancy projects, and by 1986, the cumulative total production of geotextile was about 1 million square meters. Into the 90 's, geotextile applications developed faster, 1992 woven geotextile consumption of more than 90 million square meters. In 1998, the heavy flood occurred, the weaving cloth dosage has exceeded 100 million square meters/year. Nonwoven Geotextiles 1995 consumption reached 65 million square meters, so far its use has more than 100 million square meters/year. According to such a development process, the development of the industry is very potential.
