Common methods like over-excavation and chemical stabilization are actually costing you more than you realize. In this chart, we compare the pros and cons of several soil stabilization techniques and how much aggregate is required. How does your current method stack up? Click the chart above to compare.

Tensar has designed a Subgrade Improvement Pocket Card that allows you to visually estimate subgrade strength. You can also use it to quickly determine your cost to improve the subgrade by using common methods like over-excavation, geotextile and geogrid.

TriAx Geogrid is Your All-Weather Solution
Tensar’s TriAx Geogrid improves site performance by stabilizing poor soils more efficiently. Here's the benefits you can expect on your next project:
Faster Installation: Less aggregate to install means there's less undercutting, backfilling, and disposal. Also, no skilled labor or specialized equipment are required for installation. With less to do, you can expect faster installation, often shaving weeks off construction schedules.
TriAx Geogrid can be installed in all types of weather, unlike other methods that have specific temperature and moisture requirements and long curing times.

an overview of TriAx Cost Savings.
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.
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 saved approximately $1 million on this award-winning project.
Aggregate reduced by 17 inches and avoids additional WDNR permitting.
TriAx Geogrid reduces overexcavation
and replacement materials by 50% on

Recycled Asphalt Pavement (RAP) was used in conjunction with TriAx to minimize site haul-off and speed up construction.
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.
