Geosynthetics have become an indispensable part of highway, railway, airport runway, bridge, tunnel and culvert. The above problems can be solved by soft foundation treatment, reinforced embankment, reinforced pavement bed, reinforced soil bridge, pile net reinforced subgrade and so on.

Using polyester warp geogrid can build highway, railway embankment high and steep slope, save land resources, save labor and material, especially effective for seismic load. According to safety factor, design embankment of various slopes, can use in situ soil as filling, greatly save project cost and time.

The reinforced embankment is constructed by polyester warp geogrid, which can form a flexible whole foundation with strong bearing structure. The comprehensive performance of embankment is improved and the thickness of auxiliary building is reduced by reinforcement. The strength of polyester warp geogrid is high, which can avoid the failure of embankment caused by the fracture of geotechnical material under excessive strain caused by load. Polyester warp knitted geotextile, especially in soft soil foundation, depends on the strength, freeze-thaw and durability of reinforced embankment on frozen soil.

In order to prevent uneven settlement of railway embankment. Mesh size, high strength rib and durability of polyester warped geogrid, maximum distribution of load, improved load distribution and increased bearing capacity of foundation. Make the ballast bed form a solid platform with flexibility. In some special sections, high-strength local reinforced geogrid can effectively restrict the lateral displacement of the foundation, maintain the integrity of the building and improve the bearing capacity of the foundation and reduce the maintenance cost.
