TERRAM PW9 Geotextile Robust Trackbed Separator

TERRAM PW9 Geotextile Robust Trackbed Separator

Market Sectors


TERRAM PW9 is a Robust Separator for trackbed, designed where the sub-grade soils are good but contain angular stone. PW9 is a next generation separator geotextile, used where there is a significant amount of coarse granular particles 14mm and above.

TERRAM PW9 is a mechanically entangled needle-punched geotextile robust separator/filter that provides protection from angular stone damage.


  • Suitable for good soils containing angular stone
  • Robust non-woven geotextiles protect the separation function
  • Separates ballast and angular sub-bases
  • Engineered to provide additional strength to resist damage from large angular stone particles
  • Manufactured from high tenacity UV stabilised virgin polypropylene fibres to provide long term durability in all soil types
  • Manufactured using a randomly orientated web to provide completely isotropic properties
  • Excellent uniformity with high permeability and low pore size for soil filtration
  • Network Rail approved
  • Network Rail "Product Accepted" - PA05/05860

TERRAM Geosynthetics provide solutions for permanent way applications where loss of rail track alignment caused by sub-grade erosion leads to costly maintenance and the complication caused by having to plan and temporarily close the track for its renewal.
