What are Geogrids?

A geogrid is a geosynthetic material used to stabilize soil. Today, more pavement designers are choosing to implement geogrids to improve the performance of the aggregate within pavement structures to combat increasing material costs, withstand increasing traffic loads and inadequate pavement structures created with traditional pavement sections. 

How do geogrids work? Geogrids have openings, called apertures, which allow aggregate to strike through and provide confinement and interlock. Geogrids can improve the long-term performance of paved and unpaved roadways by minimizing aggregate movement and maintaining modulus values. 

How Geogrids Work


TriAx Geogrid at Work in the Real World

Due to its ability to efficiently confine aggregate, TriAx reduces the required aggregate thickness while improving the overall performance.
