🚀 Research Confirms: and are transforming road construction.

According to a University of Illinois study, these deliver powerful benefits:

*50–200% increase in base-course stiffness
*Over 50% reduction in rutting
*20–40% thinner aggregate layers
*Traffic Benefit Ratio of 2.0–3.0 — roads lasting 2–3× longer
*Savings of $100K–$500K per mile

Real-world proof:
On I-90 near Chicago, geogrids cut base thickness from 18" to 10" with zero rutting after 5 million ESALs. Airport and rail tests showed similar gains — 33% less aggregate and up to 70% fewer ruts.

In an era of rising material costs, geosynthetics offer a smarter, more sustainable way to build stronger, longer-lasting infrastructure.
