Composite railway sleepers' advantages

composite railway sleepers

The main drivers for Lankhorst developing KLP® polymer railway sleepers made out of specifically selected 100% recycled plastics were the ban on creosote and restricted availability of hardwood. The KLP® Hybrid Polymer Sleepers have high end properties and keep these properties during their expected service life of over 50 years. They are virtually maintenance free and an excellent alternative for wooden or concrete track sleepers, turnout bearers and bridge transoms.

  • KLP® Hybrid Polymer Sleepers do not rot, splinter and are impervious to moisture, fungus and insects

Composite railway sleepers & sustainability:

  • 100% recycled & 100% recyclable
  • Upcycling from waste material to high end application
  • Low carbon footprint
  • No leaching into ground water
  • Low Life Cycle Costs; long expected life time of over 50 years


Testing & Type Approval:

  • They are approved by London Underground for use in track
  • They have reached full type approval by Praserana for use in Malaysian track
  • Currently installed in many test tracks around the globe


Easy installation of KLP® Hybrid Polymer Sleepers:

  • The same tools can be used for the installation of composite railway sleepers, as for wooden sleepers
  • Suitable for any type of fastening system
