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.

True Measure of Performance:
Not All Geosynthetics are Created Equal

Tensar TriAx Geogrid has been tested extensively to ensure
long-term performance and value.

Your reputation is at stake anytime your stamp is used on a design. At Tensar, we don’t take this lightly. That’s why we have invested extensively in research and testing of our TriAx Geogrid, proving its design and performance parameters time and again. You can use your stamp with confidence every time TriAx Geogrid is specified in a design. Don’t risk using products with unproven technologies.

TriAx Geogrid at Work in the Real World

TriAx Geogrid has helped pavement engineers around the world optimize their designs to get the longest service life for their budget. Due to its ability to efficiently confine aggregate, TriAx reduces the required aggregate and pavement thickness while improving the overall performance. Here are just a few examples of how TriAx Geogrid saves money and extends pavement life.

Cost Savings

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