Tensar Geogrids
Asphalt Pavement Interlayers for Crack Prevention
Tensar interlayers reinforce asphalt layers to reduce reflective cracking and extend service life.
Nexterra's Tensar Geogrids bring proven engineering and innovation to modern soil stabilization and pavement reinforcement. As the original pioneer of geogrid technology, Tensar has continually advanced material science and structural design since the late 1970s, delivering systems that enhance bearing capacity, reduce deformation, and extend infrastructure longevity across every soil type and climate.
Engineered Performance for Every Application
Tensar Geogrids improve soil performance by interlocking with aggregate, creating strong, stable platforms that distribute loads efficiently. Their geometric precision and material integrity make them ideal for highways, parking facilities, airfields, and industrial sites where reliability is nonnegotiable. The technology converts weak, variable subgrades into resilient foundations that perform under the most demanding conditions.
- Advanced aperture geometry confines aggregate to prevent lateral displacement and strengthen the entire load-bearing structure.
- Rigid junctions maintain dimensional stability under repeated traffic, resisting deformation and preserving pavement uniformity.
- High-tensile polymer composition delivers exceptional resistance to chemical and environmental degradation, ensuring long-term durability.
- Reduced aggregate requirements of up to seventy percent accelerate construction timelines and lower overall project costs.
Tensar Geogrids integrate seamlessly into roadway, rail, and foundation systems, providing immediate performance gains and measurable lifecycle savings.
Proven Strength and Structural Reliability
Across thousands of installations, Tensar Geogrids have reshaped expectations for pavement performance, construction speed, and structural longevity. Proven under the heaviest loads and in the harshest environments, these systems transform weak foundations into reliable, enduring surfaces that stand up to decades of use. Each installation tells the same story of precision, efficiency, and measurable improvement in how infrastructure performs.
- Pavement structures reinforced with Tensar Geogrids resist rutting and fatigue cracking, maintaining smoother, safer surfaces for longer periods of service.
- Optimized designs achieve full structural strength with thinner aggregate layers, reducing excavation, hauling, and material costs across the project lifecycle.
- Enhanced compaction and stiffness retention preserve pavement uniformity, improving long-term stability and performance consistency under repeated loading.
- Field-tested resilience in both extreme cold and high-heat environments ensures dependable performance from frozen tundra to humid coastal climates.
Every project built with Tensar reinforcement reflects decades of scientific innovation and practical engineering expertise, turning modern infrastructure into a model of lasting strength and economic efficiency.

Proven Results in the Field
Independent research and full-scale testing continue to validate the long-term performance of Tensar reinforcement. By strengthening the aggregate matrix and enhancing confinement at the subgrade interface, Tensar Geogrids deliver measurable improvements in service life, load distribution, and structural reliability. Their engineered precision turns ordinary materials into high-performing foundations that meet the toughest demands of modern infrastructure.
- Documented pavement life extension of more than fifty percent compared with unreinforced systems, proven through decades of monitored installations.
- Noticeable reduction in maintenance frequency and lifecycle cost as pavement structures maintain integrity through extended service intervals.
- Increased bearing capacity that allows construction on marginal soils without compromising load performance or long-term stability.
- Structural efficiency equivalent to several additional inches of unreinforced aggregate, reducing resource consumption and minimizing environmental impact.
Every installation confirms the same engineering truth: Tensar Geogrids redefine how loads move through the ground, transforming soil into structure and stability into long-term value.
Upstream and Downstream Load Integrity
Tensar Geogrids operate as a continuous reinforcement system where stress, confinement, and drainage work together in precise balance. From the downstream bearing layer to the upstream surface, each junction and aperture functions as part of a unified network that stabilizes the entire pavement structure. The result is a seamless equilibrium between load control, soil confinement, and moisture management that preserves strength through every cycle of use.
- Aggregate interlock distributes weight uniformly, preventing localized strain and preserving foundation stability under repeated traffic loads.
- Controlled pore geometry promotes lateral water flow, protecting the subgrade from saturation and maintaining consistent support capacity.
- Junction integrity ensures uniform alignment, keeping the reinforcement layer stable and preventing aggregate migration over time.
- Coordinated confinement maintains harmony between flexibility and rigidity, allowing the structure to adapt under stress while retaining its long-term strength.
Tensar Geogrids bring structure, soil, and flow into equilibrium, creating a pavement system that remains stable, balanced, and high-performing from the first compaction to years of continuous service.
