  • Type: Railway track
  • Location: Crawford, Nebraska (USA)
  • Area: 11,000 m²
  • Product: COLETANCHE® NTP4

Burlington Northern Santa Fe (BNSF) operates one of the largest railway networks in North America, with approximately 55,000 kilometres of track serving 28 states and two Canadian provinces.

BNSF identified several sections of track that require modernisation to improve the efficiency and reliability of their infrastructure. The BNSF engineers chose to treat the upper part of the clay with lime and cover it with a COLETANCHE® geomembrane that resists chemical damage. The geomembrane prevents water from coming into contact with the clay surface.
