Biaxial Geogrid

Biaxial geogrids are made from polypropylene (PP) or high-density polyethylene (HDPE) through extrusion, punching, and biaxial stretching in both longitudinal and transverse directions. Featuring a mesh structure with balanced load-bearing capacity in both directions, they are widely used as general-purpose geosynthetic reinforcement materials for subgrades and pavements.

Ⅰ. Product Features‌

·Comparable tensile strength in both longitudinal and transverse directions, ensuring strong overall load-bearing performance in two-way stress conditions

·Strong interlocking between mesh apertures and soil particles, effectively constraining lateral expansion and deformation of soil

·Distributes upper loads to significantly reduce differential settlement of foundations

·Effectively mitigates reflective cracking in pavements and reduces rutting and collapse distresses

·Resistant to acid/alkali corrosion, aging, creep, and extreme temperatures (high and low), ensuring long service life

·Easy to install, securely overlapped, and simple to construct with high efficiency

‌Ⅱ. Engineering Functions‌

·Reinforce soft soil foundations

·Enhance subgrade load-bearing capacity

·Stabilize subgrade structure

·Reduce subgrade deformation

·Extend road service life

·Reduce maintenance costs

‌

Ⅲ. Application Scenarios‌

·Subgrade reinforcement for highways and municipal roads

·Soft ground improvement

·Road widening and joint treatment at new-to-existing pavement interfaces

·Foundation reinforcement for industrial sites, parking lots, and freight yards

·Reinforcement of railway subballast layers

·Shallow reinforcement of embankments and dikes

·Ground leveling and stabilization for plazas and open areas
