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 is the Innovative
and Sustainable Solutuion

Innovations Need Faster, Bolder Adoption

Adopting proven, innovative technology is an easy way to raise the standards of our infrastructure while being more efficient with our budgets and time. We urge road contractors and transportation offices to accelerate the adoption of high-impact materials and techniques that prolong the useful life of roads and highways while making them safer and more reliable.

Tensar’s geogrid technology is a prime example. Building better pavements with TriAx Geogrid is a simple but powerful way to deliver long-lasting roads with lower construction and maintenance costs. Less material is needed when using geogrids, which speeds construction. With over 1 million ESALs of research to back-up its performance, geogrid has proven itself time and again to extend the life of pavements, which reduces the maintenance costs associated with those roads.

Faster, bolder adoption of proven innovations that do more with less will help deliver the projects needed to improve our national transportation system. America’s future will be shaped by the infrastructure choices we make today. That’s why Tensar puts its experts to work, showing contractors and engineers how to build smarter infrastructure using geogrid technology. Learn more...

More Sustainable Roadway Construction

Recently, Tensar has helped complete several projects which use RAP (Recycled Asphalt Pavement) in a different way: as a recycled aggregate material in a mechanically stabilized layer. Especially on reconstruction and widening projects where space is often tight and surrounding roads take a beating from construction traffic, this approach can deliver big benefits. The RAP can be used on the same project where it is generated, saving the cost, traffic, and resources required to remove the millings and bring in new aggregate material.  Learn More...



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.

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.
