Software Solutions

Tensar+ also provides access to our popular TensarSoil software for Retaining Walls & Slopes 

TensarSoilFully interactive, TensarSoil Software allows you to enter and modify the geometry of the project, the degree or design of the geogrid, additional loads and/or soil characteristics to determine stability data and material costs instantly.

Used successfully in Europe, Asia, and other regions for more than two decades, the latest version has been expanded to assess the feasibility, potential performance, and cost benefits of each of our geogrid reinforced systems, including wall systems of containment Mesa, SierraScape Systems of retaining walls and tensile temporary walls.

A Costly Mistake: Price vs. Performance

IMG_4135Price undoubtedly drives the bottom line, but what might seem like the cheapest option at first could cost more to install. In addition, the cheapest option could have the poorest performance, which requires additional maintenance costs in the future. Learn how high-performance Tensar geogrid can cut construction costs and future maintenance costs in this article. You can also see how various performance scenarios played out on a recent Kiewit project.

How Do
Geogrids Work?


How do geogrids work? Geogrids have openings, called apertures, which allow the 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. Tensar InterAx geogrid incorporates advanced material science and optimized geometry to provide exceptional performance and value across a wide range of materials and construction applications. This creates the most efficient stabilized layer that retains stiffness over time to enhance performance. The result? You get a more cost-effective, higher-performing solution.

How to Install InterAx Geogrid


Our lightweight rolls are easy to handle and cut in the field. They make it simple to adapt to curves and utility projections. The biggest
advantage in installation – you can roll InterAx 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.
