Railways
All aboard stable railways that get you to your destination.
Build safe, stable railways in the most challenging of conditions


A typical railway must withstand the most challenging demands – weather combined with the weight, speed and frequency of loads travelling its rails. Add in a curveball like permafrost or muskeg and you could have a nightmare on your hands. That’s where Tough Cell can make the difference between striking out and hitting a home run.
Paradox’s Tough Cell, a cellular confinement and soil stabilization product made of a Novel Polymeric Alloy Geocell, is uniquely suited to constructing railway in permafrost and muskeg areas, where an unstable substrate can lead to lateral spreading of ballast and differential settlement of the rail bed. Tough Cell’s honeycomb structure provides lateral restraint of ballast – and leads to the entire track settling together. That extends the life of the railbed and lowers cost of maintenance.
Proper application of Tough Cell in permafrost conditions can also prevent melting, which further preserves rail bed integrity.
Advantages:
- Reinforces track substructure, and stabilizes ballast layers
- Provides lateral restraint (versus the lateral spread of traditional rail bed construction)
- Reduced settlement of ballast materials and fouling by sub grade attrition
Benefits:
Increased strength and resilience Reduced maintenance Lower total cost of ownership
