Risks to your project come in many forms—like weather, supply chain, material costs, labor, and permits. But so do opportunities to generate additional value. When you encounter soft soils on a site, finding the best solution to repair them is a critical step in early-stage construction. Traditional soil stabilization methods like over-excavation or chemical stabilization (e.g. soil cement) can solve the problem—but they also slow you down, drive costs up, and add risk.

Integrating advanced geosynthetic solutions in your design can deliver major advantages at an economical price.

Geogrids—Know the Differences

Geogrids aren’t a one-size-fits-all solution. Different products perform differently and knowing how to compare them is essential for project managers, engineers, and contractors. They also come in a variety of forms—biaxial (BX), TriAx®(TX), and multi-axial, multi-shape H-Series (HX) and multi-axial InterAx (NX)—each having their own geometries, materials, and performance profiles. While they might look similar, their performance can differ significantly based on their shape, material properties, and application being used. The best way to compare geogrid performance is with full-scale testing.

The Tensar® Suite of Geogrids

Understanding the application and performance goals for your project are key to choosing the right geogrid. Tensar offers a suite of geogrids to fit a variety of applications and your performance or budget needs.

Tensar’s original BX geogrid

Our original Biaxial BX geogrid changed the game when it was first introduced for soil stabilization in the 1980s. Today, while it’s still commonly used, more advanced geogrids will perform better depending on your project needs, and decrease the overall project installation cost, too.

More advanced geogrids, like the InterAx and H-Series, evolved from the BX geogrid, providing longer service life and greater cost savings.

InterAx geogrid

Tensar’s highest-performing geogrid, InterAx, offers advanced material science and optimized geometry, and is the preferred solution for higher-risk and permanent applications like crane pads and paved roads.  InterAx often provides superior strength and requires less aggregate, saving both time and material costs.

H-Series geogrid

The H-Series geogrid represents how our geogrid technology meets in the middle by offering optimized geometry at a more economical cost. It’s a reliable, resilient solution for low-risk or temporary applications where performance thresholds are more forgiving.

Success Story: Springbank Off-Stream Reservoir

The Springbank Off-Stream Reservoir required reliable, internal, unpaved access roads to support both construction and long-term operations. Tensar H-Series geogrid delivered stronger performance and meaningful project savings.

Situation: 

• Dry reservoir designed to temporarily store floodwaters 
• High priority for roadway reliability and long-term performance 
• Original design specified legacy geogrid (TriAx TX5)

Challenge: 

• Providing better performance at a competitive cost

Solution: 

• Engineers saw an opportunity to switch to Tensar H-Series HX5.5 geogrid, a higher-performing—but still economical—solution

Advantages: 

• Higher performance at a competitive cost 
• Reliable design based on full-scale testing and validated performance data 
• Material & Cost Savings: 
  • Reduced aggregate cross-section from 450 mm to 300 mm 
  • Lowered aggregate quantity needed 
  • Accelerated installation 
  • Delivered measurable cost savings 
  • Maintained original performance requirements

Outcome: 

• A stronger, more efficient access road system that supported the project schedule, improved durability, and minimized long-term maintenance needs
