Characteristics of Biaixal Stretch Geogrid

High-Strength Geosynthetic Material:

Biaxial stretch geogrid is manufactured using high molecular polymer (PP) through advanced processes including extrusion, punching, heating, and biaxial stretching, offering stable chemical properties, high resistance to mechanical damage and durability, high friction coefficient with sand and gravel.

Outstanding Tensile Performance:

Biaxial stretch geogrid possesses high tensile strength, high plane torsion modulus, good creep resistance. Exceptional strength in both vertical and horizontal directions, ensuring robust performance in demanding environments.

Grid-Like Structure:

The square-shaped grid design enhances force bearing and diffusion within soil, promoting an effective interlocking system. It can improve the bearing capacity of the foundation and increase the diffusion angle. The same effect can be achieved under the axial action of the same load, and the filling thickness can be reduced.
