Advantages
Less signal disruption
Magnetic characteristics of steel reinforcement disrupt signals in point blocking circuits; Combar® is non-magnetic and non-magnetisable: The risk of delays or downtimes of the railway due to signal disruptions is reducedVersatile
The electromagnetic neutrality of Combar® makes it ideal for use in the following areas:
- Slab tracks
- Switchgear facilities
- Concrete supporting layers (ballastless track)
- Airfields
