Biaxial Geogrid Products: BX1100, BX1200, BX1500 & More

Tensar geogrids work by mechanically interlocking with aggregate particles placed on top of or around them. As load is applied, the grid restrains lateral movement of the aggregate, spreading the load over a wider area. This confinement effect reduces rut formation, extends pavement life, and can significantly reduce required aggregate or subbase thickness compared to unreinforced designs.

A biaxial integral geogrid is manufactured from a single sheet of polypropylene that is punched and drawn to create a monolithic grid structure. Because it is formed from one continuous material rather than bonded strands, it delivers consistent tensile strength at every junction. This integral construction provides reliable two-directional load distribution and long-term durability without junction weakness.

Biaxial geogrids are commonly used in roadway construction for paved and unpaved roads, parking lots over soft subgrades, retaining walls, geosynthetic-reinforced soil slopes, bridge abutments, railroad and airport infrastructure, and access roads for mining, logging, wind farms, and landfills. They are suitable wherever soil reinforcement and load distribution are required.

Biaxial geogrids have a rectangular aperture pattern that distributes load in two directions — length and width. Triaxial geogrids feature a triangular aperture pattern that spreads load radially in multiple directions. Biaxial grids are well-suited for reinforcing walls and slopes, while triaxial grids are often preferred for base course stabilization beneath pavements due to their omnidirectional load-spreading capability.

Yes. Polypropylene biaxial geogrids are resistant to chemicals commonly found in soil, including acids and alkalis, and are also formulated to withstand UV radiation for exposed applications. They are designed to resist mechanical damage during installation, making them suitable for permanent infrastructure projects where long-term durability is essential.
