Slowakia railway project

Slovakia have started the rehabilitation of the infrastructure network, investing also in a new efficient railway system.

The most important project has been the main line , around 30 km to be reconstructed. The consultant has indicated an use of Geotess nonwoven geotextile and geogrids in the construction of the track substructure. The role of GEOTESS 250 geotextile has been to separate the soils out of which the railway embankment was constructed from the sub-layer, in order to keep the original characteristics of both materials. The technical specifications for the geotextile have considered:

Type, mechanical characteristics and water permeability of the materials of the embankment:
Size of granular materials of the new sub-layer
Compressibility module value
Traffic load
Resistance of the geotextile to all kind of stresses during the installation phase and during all its service life

Total quantity of non woven geotextile installed was around 200.000 sm , product from Tessilbrenta - Geotess 250 g/m2, high tenacity staple fibre polypropylene non woven geotextile, UV stabilized.
