GusjoinT-R-Ultra is a polymer-modified, hot-applied rail joint sealant designed for the long-lasting sealing of rail joints exposed to exceptionally high movement and vibration. It is specifically developed for joints between rails and adjacent asphalt, concrete or block paving surfaces where increased flexibility is required. Combining outstanding elasticity with excellent vibration-damping properties, GusjoinT-R-Ultra reliably accommodates even significant joint movements while maintaining the long-term integrity and performance of the sealing system. The product complies with the requirements of TL/TP Fug-StB.
