Tensar geogrid is one of the most trusted names in soil stabilization and pavement reinforcement. Whether you're building roads, parking lots, or working on subgrade improvement, understanding the different types of Tensar geogrids and their applications can help you choose the right product for your project and potentially reduce construction costs significantly.
This guide covers everything you need to know about Tensar geogrid products, including the InterAx, TriAx, and Biaxial product lines available through authorized distributors in Ohio.
What is Tensar Geogrid?
Tensar geogrid is a polymer-based reinforcement material used in civil engineering and construction applications. The geogrid features a grid-like structure with apertures (openings) that interlock with aggregate materials, creating a mechanically stabilized layer that distributes loads more effectively than aggregate alone.
Tensar Corporation pioneered geogrid technology and continues to lead the industry with innovative products designed for specific applications. Their geogrids are manufactured using a proprietary process that creates stiff, integral junctions capable of withstanding significant loads without failing.
Types of Tensar Geogrid
InterAx Geogrids (NX Series)
The InterAx geogrid line represents Tensar's most advanced technology, featuring a multi-aperture design with three distinct geometries: hexagonal, trapezoidal, and triangular. This unique structure provides consistent performance in all directions, making it ideal for base reinforcement where loads come from multiple angles.
Products include:
- InterAx NX850 – Heavy-duty applications, maximum stabilization
- InterAx NX750 – High-performance for demanding projects
- InterAx NX650 – Standard applications, excellent value
- InterAx NXL – Lightweight option for less demanding conditions
Best for: Road construction, parking lots, working platforms, and any application requiring multi-directional load distribution.
H-Series Geogrids (HX Series)
The H-Series geogrids offer optimized geometry for base reinforcement at a more economical price point than InterAx. They provide excellent performance for stabilizing soft subgrades and improving pavement performance.
Products include:
- H-Series HX165 – Higher tensile strength for demanding applications
- H-Series HX145 – Cost-effective base reinforcement
Best for: Soft subgrade stabilization, access roads, pavement improvement, and projects needing a balance of performance and economy.
TriAx Geogrids (TX Series)
TriAx geogrids feature triangular apertures that provide three-directional strength, improving performance over traditional biaxial designs. The geometry creates more efficient load transfer for applications with varied traffic patterns.
Products include:
- TriAx TX190L – Versatile tri-axial performance with 60mm rib pitch
- TriAx TX Type 2 – Heavy-duty with denser 33mm rib pitch for maximum reinforcement
Best for: Heavy traffic roads, container yards, truck terminals, airport taxiways, and industrial facilities.
Biaxial Geogrids (BX Series)
Biaxial geogrids provide two-directional strength with rectangular apertures, offering equal performance in both machine and cross-machine directions. These cost-effective products are proven performers for base course stabilization.
Products include:
- BX1200 – Tight apertures (1.0" x 1.3") for fine aggregate
- BX1300 – Large apertures (1.8" x 2.5") for coarse aggregate
- SQ2020 – Economy option with square apertures for light-duty applications
Best for: Roads, parking lots, base course stabilization, subgrade improvement, and unpaved roads.
Tensar Geogrid Applications
Road Construction & Rehabilitation
Tensar geogrid is widely used in road construction to stabilize subgrade soils and reduce the required thickness of aggregate base courses. This can result in significant cost savings while improving long-term pavement performance. The geogrid creates a mechanically stabilized layer that distributes wheel loads over a wider area, reducing stress on the subgrade.
Parking Lots & Commercial Paving
Commercial parking lots benefit from geogrid reinforcement, particularly in areas with poor soils or heavy vehicle traffic. The InterAx NX750 is commonly specified for parking lot applications due to its balance of performance and cost-effectiveness.
Working Platforms & Temporary Roads
Construction sites often require temporary roads and working platforms over soft ground. Tensar geogrid allows these structures to be built with less aggregate, reducing material costs and construction time.
Soil Stabilization
For sites with weak or unstable soils, Tensar geogrid provides mechanical stabilization that allows construction to proceed without expensive soil removal and replacement. This is particularly valuable in Ohio where clay soils can present challenges.
Benefits of Tensar Geogrid
- Reduced Aggregate Requirements: Geogrid reinforcement can reduce aggregate base thickness by 30-50% while maintaining equivalent performance.
- Lower Construction Costs: Less material means less trucking, less excavation, and faster construction timelines.
- Improved Performance: Mechanically stabilized layers outperform unreinforced aggregate over time, with less rutting and deformation.
- Extended Pavement Life: Better load distribution reduces stress on underlying layers, extending overall pavement life.
- Sustainable Construction: Using less aggregate reduces the environmental impact of construction projects.
- Proven Technology: Tensar geogrids have been used successfully on thousands of projects worldwide since the 1980s.
How to Choose the Right Tensar Geogrid
Selecting the appropriate geogrid depends on several factors:
- Subgrade Conditions: Weaker soils require stronger geogrids like the NX850 for maximum base reinforcement.
- Traffic Loads: Heavy truck traffic or industrial applications benefit from TX Type 2 or BX1300.
- Value Engineering: H-Series geogrids offer strong performance at a more economical price point than InterAx.
- Budget Constraints: Products like NX650 or SQ2020 offer excellent value for lighter applications.
