Benefits of Polyurethane Compaction Grouting for Railroad Crossing Stabilization
1. Minimal Disruption to Rail Traffic
Polyurethane grout cures rapidly—often within minutes—allowing for quick project turnaround and reduced track downtime, which is critical for active railroad crossings. Projects completed in days instead of weeks or months.
2. Precise Soil Stabilization
The expanding polyurethane foam penetrates loose or unstable soils and compacts them as it expands, increasing load-bearing capacity directly beneath the slab without over-excavation.
3. Void Filling and Slab Lifting
It effectively fills voids under concrete slabs caused by erosion, washout, or settlement, and can gently lift sunken slabs back to their original position.
4. Water-Resistant and Long-Lasting
Polyurethane is highly resistant to water and chemical intrusion, making it ideal for high-moisture environments often found near rail infrastructure. It won’t degrade over time like other materials.
5. Lightweight Yet Strong
Unlike cement-based grouts, polyurethane adds minimal weight to the subgrade while still providing significant strength and support—important in areas where additional load could worsen settling.
6. Non-Invasive Application
Injection is done through small-diameter holes drilled through the concrete slab, avoiding major excavation and preserving the integrity of the surrounding rail infrastructure.
