  • TriAx® Geogrids have three principal directions of stiffness that are further enhanced by their rigid triangular geometry.
  • Unique aperture geometry forms a hexagonal junction shape with superior junction strength and stiffness to mitigate radial stress imparted from a trafficked surface.
  • Ideal for improving the service life of paved and unpaved surfaces while further reducing excavation and pavement component thickness requirements.
  • Create an enhanced, mechanically stabilized composite material for constructing over soft soils.

Tensar® TriAx® (TX) Geogrids

Tensar® TriAx® Geogrid is an advanced product specifically designed for trafficked surfaces. TriAx Geogrid’s multi-directional properties leverage triangular geometry, one of construction’s most stable and widely utilized shapes, to provide an enhanced level of in-plane stiffness. Its triangular structure, coupled with improved rib and junction geometry, offers the construction industry an improved alternative to conventional materials and practices.

TriAx Geogrid is manufactured from a punched polypropylene sheet oriented in multiple, equilateral directions to form its triangular apertures, resulting in high radial stiffness throughout the full 360 degrees. This feature yields a more efficient product that delivers optimal in-service stress transfer from the aggregate to the stabilizing geogrid.

Triaxial Geogrids Have an Effective Pattern

Before covering the other advantages of triaxial geogrids, let's look at some of their physical characteristics. After all, it is the unique pattern of the triaxial grid that contributes to its many advantages.

Generally, there are three classifications of geogrids:
1. Uniaxial (UX)
2. Biaxial (BX)
3. Triaxial (TX)

Uniaxial and biaxial grids have ribs that run in only two directions. This structure creates a more traditional gridded pattern. In contrast, triaxial grids have ribs running in three directions.

One set runs along the length. The second set runs along the width. The third set of ribs runs diagonally across the grid created by the first two sets of ribs. As you will see below, this pattern contributes to the benefits of triaxial grids. Additionally, triaxial grids are also often made with dense polymeric material. Now that you know about that basic physical difference, here are more reasons why triaxial grids are effective.

History shows that triangles are one of the strongest shapes for construction. This holds true for triaxial geogrids as well. The triangular apertures of a triaxial geogrid contribute to a great bearing capacity. That's why triaxial geogrids are such a great option for road construction.

Triaxial Geogrids Have High Tensile Strength

The pattern of triaxial geogrids lends itself to high tensile strength. The fact that the ribs overlap each other in three directions allows these geogrids to withstand high amounts of tension when in use. The production process of these grids also contributes to this strength.

Often, a triaxial geogrid begins as a solid sheet of polymeric material. The triangular apertures are then punched out of this sheet. Since these triaxial geogrids are formed from a single object, they are stronger than other grids that are woven together.

Sound construction is all about avoiding structural failure. Geogrids help prevent this failure through their ability to withstand forces.

One of the means by which we can evaluate a triaxial geogrid's reliability is through its intersection also known as a junction. The junction integrity is defined by something called ultimate strength. Here is a definition for that term:

Triaxial Geogrid Junction

Ultimate junction strength – The maximum amount of force a junction can withstand before breaking.

The higher the ultimate junction strength, the better the junction integrity.

There are two main reasons why triaxial geogrids have great junction integrity:

1. Ribs cross in three directions making for thicker junctions

2. Each rib is made from a very dense polymeric material

These two features help the triaxial geogrid junctions remain intact over time.

Triaxial Geogrids Are Useful for Both Paved and Unpaved Roads

By now, you know that triaxial geogrids are a great option for reinforcing paved roads. You may even be able to reduce the total amount of pavement needed for the project. But what if you are creating a road with no pavement at all?

In the case of unpaved roads, triaxial geogrids remain a great option. Unpaved roads are often made using the materials listed below:

  • Gravel
  • Sand
  • Crushed Stone

These materials are less resistant to wear than the harder paving materials mentioned earlier. Because of this, unpaved roads are more likely to breakdown over time. A triaxial geogrid can compensate for this to a degree. Using these grids in unpaved roads can help to extend the lifespan of the road.

Triaxial Geogrids May Prove to Be the Preferred Geogrid of the Future

The advantages listed above are evidence of the fact that triaxial grids are an advanced material. This state-of-the-art technology appears to outperform other geogrids in many ways.

Although currently a relatively new development, triaxial grids may become the go-to geogrid in years to come, if for no other reason than these grids have the potential to give construction projects a lower price tag and a longer lifespan.

The earlier you adopt triaxial grids as a part of your construction process, the sooner you can reap those benefits.
