Biaxial geogrid, made of high molecular polymer, is extruded into sheet and then punched into regular mesh pattern, and finally stretched in longitudinal and transverse directions.
Features: 1. With high tensile strength in longitudinal and transverse directions
2.This structure can provide an chain system of more effective force bearing and spreading for the soil.
Application: Mainly applied in highway, railway, slope protecting projects etc.
1)strengthen land loading capacity and extend its service life.
2) convenient to construct ;
reducing project cost and maintenance cost.
