Railroad

Geosynthetic products are used in railroads to provide filtration, separation, and reinforcement under ballast. AREMA typically requires needle punch nonwoven geotextiles for this application; however, Hanes Geo also offers a range of geogrids for ballast and sub-ballast reinforcement.

TerraTex® nonwoven geotextiles are made up of polypropylene fibers. These fibers are needled to form a stable and durable network such that the fibers retain their relative position. It is non-biodegradable and resistant to most soil chemicals, acids, and alkali with a pH range of 3 to 12. Unless noted otherwise, all values are minimum average roll values (MARV).

  1. At the time of manufacturing. Handling, storage, and shipping may change these properties.
  2. Value represents maximum average roll value.
  3. Transmissivity is measured at Gradient 1.0 and 3.5 psi load with 15-minute seating time between steel plates.
