PP Biaxial Geogrid SG1100

       

  


 

Introduction: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.

Biaxial geogrid is manufactured from polypropylene,mainly applied in strengthening soft ground of highway,railway,slope protecting projects, airfields etc.It can increase stability and loading capacity of fundus,prolong the project life.
