plastic grid

Specifications

plastic grid

 Biaxial plastic Geogrid is manufactured from Polypropylene. It is produced through the process of extruding, punching, heating, longitudinal stretching and transverse stretching. These structure can provide soil a perfect and efficient standing and diffusing chain system a chain moduli, which is used broadly to enable the permanent bearing capacity of roadbed. and so on.

Application

• Soft foundation reinforcing for highway, railway, slope protecting projects, landfill sites
• Improving bearing capacity of foundation
• Preventing road surface from cracking and subsiding
• Convenient to construct, reducing cost and maintaining expense for the project
• Providing stability for slopes and avoid the losing of the water and soil
