Biaxial Plastic Geogrid

Product Description

Production Introduction

Biaxial geogrid is manufactured from High Density Polypropylene, produced through the process of extruding, punching, heating and longitudinal and transverse stretching.

It has large tensile strength and is widely used in the reinforcement of soft foundation.

Performance

High tensile strength at both longitudinal and transverse direction.

Application

Soft foundation reinforcing for highway, railway;

Slope protecting projects;

Landfill sites.

Advantages

Improving bearing capacity of foundation;

Preventing cracking and subsiding;

Convenient to construct, reducing cost and maintaining expense.
