Failed fastening
When the spike head breaks, the rail cannot be safely fastened in the original position.
Problem
A broken spike disables the rail fastening
Sleeper replacement risk
The standard approach means removing and replacing the concrete sleeper, often with additional related work.
Time demanding
Sleeper replacement requires a technical procedure, manpower and a closure or significant operating restriction.
Traditional solution
Replacing the complete sleeper
The conventional method replaces the damaged sleeper with a new one. This is physically demanding, especially for a concrete sleeper of around 340 kg, and requires several follow-up steps.
- track closure for several hours,
- intervention in track stability and geometry,
- ballast compaction and follow-up procedures,
- difficult implementation in winter conditions.
New solution
Hole regeneration without sleeper replacement
We drill out the broken sleeper spike, clean the hole and prepare it for a regenerative insert. It is fixed with a chemical anchor to restore functional rail fastening.

Benefits for infrastructure managers
Less downtime, less intervention, faster restoration
Repair during operation
Minimises closures and traffic restrictions.
Track stability
No disturbance to track geometry and superstructure stability.
Sleeper restoration
The damaged sleeper is regenerated instead of immediately replaced.
Cost efficiency
Less material, handling and related work.
