TERRAM PW4-LA is a reinforced trackbed separator designed where the sub-grade is weak, ie. soft and boggy conditions.

TERRAM PW4-LA is a composite formed from TERRAM PW1 and Tensar SSLA30 geogrid. Tensar SSLA30 improves track life and performance by stiffening ballast laid over weak ground. The advantage of TERRAM PW4-LA is the speed at which a geotextile filter and grid reinforcement can be laid in a single pass with the beneficial effect on construction costs.

Features:

  • Suitable for weak sub-grade soils (soft & boggy conditions)
  • Helps to improve track life by stiffening ballast laid over weak ground
  • The structure and composition of PW4 provides a long term mechanical performance and chemical resistance, even when used in very aggressive conditions.
  • Improves the load bearing capacity of soil when placed at the base of ballast, constraining the aggregate by laterally confining it, providing the necessary support.
  • Manufactured using large aperture bi-axially orientated geogrid developed specifically for railway applications and use under ballast. PW4-LA provides the ideal dimensional characteristics for the effective interlocking of ballast within the geogrid apertures.
  • Network Rail approved
  • Network Rail "Product Accepted" - PA05/04556
