Biaxial Geogrids for Soil Reinforcement
Biaxial geogrids are widely used in soil reinforcement projects where weak subgrade conditions require improved load distribution and structural stability. When properly installed within granular layers, the grid structure creates strong aggregate interlock that increases bearing capacity and significantly reduces long-term settlement.

Practical Soil Reinforcement Applications
Road Base Stabilisation
In road construction over soft soils, biaxial geogrids are installed between subgrade and aggregate base. Aggregates of 20–40 mm ensure strong interlock. Compaction in two stages is recommended.
Logistics Yards and Container Platforms
Heavy-load areas benefit from biaxial geogrid to reduce aggregate thickness by 20–30% while maintaining load-bearing performance. High tensile grids prevent long-term deformation.
Temporary Construction Roads
Geogrid beneath aggregate layers improves surface stability, allowing reuse of materials in multiple project stages.
