Geo-synthetic has been utilized for many years in many architecture areas in the whole world. With the merits of low cost and construction convenience, it has been widely utilized in the constructions of road, railway, dyke, and cloacae etc. Especially for road and railway, the application of geo-synthetic could reduce the protection fares. Generally speaking, in industrial textile Geo-synthetic is most mature for road construction. Nowadays it has been widely applied and produced. In geo-synthetic materials, different weaving structures are adopted in producing. According to the purposes for utilization, a great amount of net-like fabric is urgent to be used in many occasions where need to be reinforced. These kinds of net-like fabric are named geogrid. Introduction Processed of polypropylene extended both weft and warp, it has great tensile strength. The structure can provide a chain modulus which suit for long-term reinforcement of basement loading. Purpose: Applied in different kinds of basement reinforcement of highway and railway, protection of slope, airport, port, etc. Function 1Enlarge road loadings; Lasting the life of road. 2Prevent the road from cracks and being sunk. 3Convenient construction, time saving, labor saving, fare reducing. 4Crack preventing. 5Strengthen the basement layer, and protect soils from being swept. 6Reduce the thickness of basement layer and reduce the construction fares.
