Pavement Stabilization for Highways, Bridge Approaches & Roadways
Roadways and transportation infrastructure are constantly subjected to traffic loading, vibration, moisture intrusion, and soil movement. Over time, these forces can create voids beneath pavement and approach slabs, leading to settlement, cracking, and uneven transitions that affect ride quality and safety.
PolyPier® systems are used to stabilize and lift settled pavement by injecting expanding polyurethane material beneath the surface. The material fills subsurface voids, densifies supporting soils, and restores slab alignment without removing the roadway section.
When properly installed, stabilization helps improve driving conditions, reduce maintenance frequency, and extend the service life of transportation surfaces.

- Restores smooth transitions at bridge approaches
- Reduces roadway settlement and faulting
- Minimizes lane closure time
- Stabilizes soils affected by water intrusion
- Provides maintenance alternative to full reconstruction
Polyurethane stabilization provides performance advantages compared to traditional slurry or reconstruction methods.
- ightweight material suitable for variable subgrades
- Expands to fill irregular void spaces
- Controlled lift for precise surface correction
- Closed-cell structure resistant to water infiltration
- Rapid cure allowing quick return to traffic
These characteristics make polyurethane systems effective for transportation environments where downtime must be minimized.
