Biaxially oriented geogrid
introduction
Polypropylene Bi-axial geogrid is based on raw material as pp, after a plastics extrusion, sheet metal punching, Longitudinal and Transverse stretching of a high-strength reinforcement geosynthetics. Be laid in the soil, through the mesh of the grid and interlock soil occlusion and the role of stress constitutes an efficient transmission mechanism is local and can be quickly and effectively in the spread to large areas of soil, Thereby reducing the local stress damage, increase the life of construction.
performance
Bi-axial geogrid with Polypropylene has high creep strength and good durability, from the soil of harmful substances (such as acid, alkali, salt and other chemical substances) and non-biological erosion, It Has a higher strength.
Applications
Bi-axial geogrid is mainly used in road, rail soft ground treatment, and slope maintenance, large-scale projects such as garbage disposal, can greatly enhance the carrying capacity of the soft ground to prevent surface cracking, collapse, convenient, reduce maintenance costs.
