What are Geogrids?

A geogrid is a geosynthetic material used to stabilize soil. Today, more contractors are choosing geogrids to improve the performance of the aggregate within pavement structures, combat increasing material costs, and save significant time on projects. 

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 Geogrid reduces the required aggregate thickness while improving the overall performance. 

Cost Savings

TriAx Geogrid saved approximately $1 million on this award-winning project.


Material Savings

Aggregate reduced by 17 inches and avoids additional WDNR permitting.

About Tensar

At Tensar International, finding solutions that lower construction costs and bring added value is our top priority. That’s why we put our experts to work, showing engineers and contractors around the world how to build smarter infrastructure using geogrid technology. With decades of research and real-world experience under our belt, our geogrid solutions bring significant cost and time savings across a wide range of civil applications like:

Soil Stabilization  |  Pavement Optimization  |  Foundations
Working Platforms  |  Walls and Slopes

We're proud to offer state-of-the-art design solutions – specialty solutions based on advanced technologies proven since 1982. Tested in the most challenging conditions, these comprehensive solutions save time, resources and money. They’ve become the standard by which others are measured.


Easy Installation

Our lightweight rolls are easy to handle and easy to cut in the field. They make it simple to adapt to curves and utility projections. The biggest
advantage in installation – you can roll Tensar TriAx Geogrids out onto the subgrade and walk on them, even in the weakest soil conditions. Adjacent rolls of Tensar Geogrids normally don’t require any connection, since aggregate fill simultaneously interlocks with overlapping geogrid apertures. A simple overlap is sufficient and no sewing is required. Watch our video to see just how easy installation can be. Or, you can download our installation guide for full details.
