Market Sectors


TERRAM PW1 trackbed separator is designed to maintain separation between the adjacent sand/ballast layers within the trackbed construction, preventing the upward movement of fine sub-grade particles.

TERRAM PW1 is suitable for where sub-grade soils are good, have sufficient strength and the particles are of even size.


  • Needle-punched geotextile
  • Suitable for good granular sub-grade soil
  • Can be used as a separation between ballast and a sand blanket
  • Engineered to provide high strength and high elongation at break
  • High puncture and abrasion resistance
  • 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" - PA05/04556
TERRAM Geosynthetics provide solutions for permanent way applications where loss of rail track alignment caused by subgrade erosion leads to costly maintenance and the complication caused by having to plan and temporarily close the track for its renewal.
