Biaxial geogrid is a high-performance geosynthetic material made from high molecular weight polymers such as polypropylene (PP) or polyethylene (PE). It is produced through a precise process of extrusion, forming, punching, and subsequent biaxial stretching in both the longitudinal and transverse directions. This advanced manufacturing technique results in a rigid, grid-like structure with uniform apertures and exceptional tensile strength in both directions.
The unique interlocking mechanism of the biaxial geogrid enables it to effectively confine and stabilize granular materials, distributing loads evenly and preventing lateral movement. This significantly enhances the bearing capacity and long-term stability of the subgrade, reduces differential settlement, and minimizes the thickness of structural layers required-thereby lowering overall construction costs.
It is particularly well-suited for applications requiring high strength and durability under repeated or static loading conditions. These include roadbed reinforcement, highway and railway embankments, airport runways, container yards, industrial platforms, and other large-area geotechnical projects. Its resistance to corrosion, chemical degradation, and environmental aging ensures long service life, even in harsh soil or weather conditions.
By improving structural integrity and prolonging pavement life, biaxial geogrid is an essential solution for modern infrastructure development.

Geogrid is manufactured from polypropylene (PP) through a series of processes including extrusion, punching, heating, and biaxial stretching (both longitudinal and transverse directions). This production method forms a high-strength grid structure that offers excellent tensile performance in both directions.
It is primarily used for the reinforcement of permanent load-bearing structures built on soft soils, such as highways, railways, embankments, and other geotechnical engineering applications.
Geogrid is widely used for reinforcement treatment of various soft soil foundations, helping to evenly distribute load stress and reduce differential settlement. It features low static electricity generation and excellent flame retardant properties, making it particularly suitable for use in coal mine environments.
Typical applications include:
Highways, railways, ports, airports, and municipal engineering projects
Support structures in coal mine roadways and recovery working faces
This material enhances structural stability and safety in both surface and underground engineering projects.
