Railway rehabilitation in Romania

tipptex BS nonwoven used in railway construction

The 4th Pan-European corridor runs between Germany and Greece/Romania/Turkey and is part of the Pan-European corridors that improve the connectivity within Europe. Rehabilitation of these railway structures improves and ensures long term stable and safe rail traffic.


In order to ensure good technical conditions for the trains, that travel at speeds up to 160 km/h, across this Pan-European Corridor and a high level of safety for the rail traffic, the rehabilitation of the infrastructure is performed.
When trains move across the rail, this can cause a pumping effect, where fine particles can move upwards into the ballast, thus leading to a faster deterioration of the support.


The introduction of Tipptex BS nonwoven into the construction as a separation and filtration layer between the subgrade and the subbase prevents the movement of soil particles into the subbase, therefore minimizing the risk of instability caused by the pumping effect and increasing the lifetime of the structure while lowering the maintenance cost.

In total over 2.000.000 m² of BS nonwoven for the project ‘Rehabilitation of Curtici-Simeria Frontier Railway’ in Romania were supplied, making it one of the biggest projects we have done up until now. A critical parameter in the successful end to this project was our ability to reliably deliver large volumes in time.
