It’s Not Just the Construction Technology at Your Fingertips That’s Boosting Construction Efficiency. It’s What’s Underfoot.

Construction technology is playing an increasingly important role in construction; connecting field personnel with management back in the office and helping contractors and engineers collaborate throughout the entire construction process. Yet, one of the key construction technologies for job site productivity isn’t digital. It’s analog…and triangular. And you don’t hold it to your ear or type on it. You walk and drive over it.

The technology is geogrid and in its latest form this tool changes the nature of the worksite. A geogrid is a geosynthetic material used to reinforce soils and similar materials. Geogrids are commonly used to reinforce retaining walls and subgrades below roads or structures. While it has been around a while, only recently incorporating the triangle shape offers the construction industry an improved alternative to conventional materials and practices.

Tensar TriAx triangular geogrids offer a better solution.

One access road near Mobile, Alabama, was a contractor’s nightmare. The unpaved road, built with fabrics, rapidly failed as the trucks were delivering fill. This same road was built with Tensar Geogrids and held up under repeated truck traffic.

When faced with the cost of losing equipment production time or wasting valuable man-hours, using TriAx Geogrids can be the best decision you make. Since they are easier to install, use less aggregate fill, and require no skilled labor or specialized equipment, TriAx Geogrids help you get in, get out, and get the job done on time.

So how do the triangles work? Use of triangular geogrid technology such as Tensar’s TriAx Geogrid provides the multiple benefits of a mechanically stabilized layer (MSL) to form a stiffer and more robust structure. Its unique design – triangular shaped apertures – increases aggregate confinement and ensures that high tensile stiffness is maintained in all directions.

The result is greatly improved soil stabilization properties, which is particularly beneficial for addressing issues with differential settlement on weak or variable sub-grades.

The thing about Tensar TriAx (triangle-based geogrid) is that you also get design software along with it. Click here to learn more about the SpectraPave4-Pro Software (SP4-PRO) design software.
