Rail Infrastructure
What is Rail Infrastructure?
Rail infrastructure includes tracks, ballast, subgrades, tunnels, bridges, and embankments that support safe and efficient rail transport. These assets experience heavy cyclic loading, vibration, and environmental exposure, requiring strong ground support for long-term reliability.
Challenges in Rail Infrastructure
- Settlement or misalignment of track beds and subgrades
- Ballast degradation causing instability in rail systems
- Soil erosion and voids beneath embankments and tunnels
- Groundwater infiltration compromising rail structures
- High costs and delays from rail line closures during repairs
Types of Polymers Used
High-Density Polyurethane Foams
- Expands to fill voids beneath foundations and slabs
- Provides lightweight reinforcement without adding load
- Cures quickly to minimize business interruption
Structural Polyurethane Resins
- Strengthens soils supporting commercial structures
- Provides rigid reinforcement for pavements and parking areas
- Extends the service life of retail and office assets
Hydro-Insensitive Polymers
- Expands and cures in wet or saturated soils
- Blocks groundwater infiltration in below-grade structures
- Maintains performance in challenging site conditions
Benefits of Rail Infrastructure Solutions
Trenchless polymer injection restores stability and safety to rail infrastructure without prolonged closures. These solutions reduce maintenance costs, extend service life, and ensure smooth rail operations under heavy and continuous loading.
