Icosit® KC 340/4

2-part polyurethane grout for rail fixing

Icosit® KC 340/4 is a flexible 2-part polymer grout based on polyurethane resin. It is designed as a vibration absorbing, load-bearing, flexible grout for the precision alignment of rails, turnouts/switches etc. Icosit® KC 340/4is also used for fixing track components to rigid substrates such as concrete slabs, steel bridge decks and tunnel invert slabs.

  • Medium axle loads of trams and light-rail vehicles
  • Noise & vibration suppression
  • Reduces erosion of concrete under baseplate            
  • More uniform load distribution into substructure
  • Watertight undersealing
  • Flexible, elastic (damping, compressible)
  • Good electrical insulation against stray currents
  • No stress peaks on anchor bolts
  • Excellent adhesion on various substrates
  • Levels out tolerances
  • Suitable as a powerful, shear-resistant adhesive
  • Absorbs dynamic stresses and prolongs the life of concrete substructure
  • Insensitive to moisture
  • Elastic (shore A 65) - compressible
  • Long life expectancy
  • Long durability, less maintenance
