Rail replacement works which VolkerRail undertook on the London Trams network earlier this year used a new track maintenance solution developed by Sika. The work \u2013 which took place during a 15-day blockade \u2013 saw a key crossover and 500 metres of embedded rail replaced and it was used as a trial of new solution.<\/p>\n
<\/p>\n
VolkerRail partnered with Sika to trial its Icosit\u00ae KC 350\/45 polymer rail grout, which is said to support improved efficiency during construction and long-term performance of the asset.<\/p>\n
Icosit\u00ae KC 350\/45 is a flexible, two-part polyurethane polymer resin grout that is used across European light rail systems. This is the first time it has been used in the UK, and should offer significant improvements in vibration absorption and long-term rail maintenance.<\/p>\n
The grout cures up to six times faster than traditional methods, helping to shorten track closure times, and can be applied using an innovative new machine, creating further labour, cost and environmental savings.<\/p>\n
This was also the first site in the world to use the innovative machine to apply Sika\u2019s Icosit\u00ae KC 350\/45 polymer rail grout, moving embedded track renewal away from traditional hand installation.<\/p>\n
Jamie Kelly, VolkerRail\u2019s programme manager, said: \u201cThe renewal of this important crossover and embedded rail was delivered on time and to the client\u2019s satisfaction. With over one hundred people on site each day, the professionalism, drive, and commitment shown by the team was exemplary. Thanks also to Sika, who supported the introduction of a new application method that helped improve efficiency and remove the need for more labour\u2011intensive activities.\u201d<\/p>\n
David Collins, National Business Manager at Sika, commented: \u201cThis is the first time Sika Icosit\u00ae KC 350\/45 polymer has been installed by machine anywhere in the world. By combining faster curing with controlled application, we have demonstrated a more efficient way to deliver embedded rail renewals, and our solution provides a clear example of how rail replacement can be delivered more efficiently with improved performance, less waste and reduced disruption.\u202f The benefits extend beyond installation, and its elastic properties reduce vibration ensuring improved ride quality and greater long-term durability too.\u201d<\/p>\n
The works which this solution was used on took place between 11th<\/sup> and 26th<\/sup> February 2026. It saw work take place near Addiscombe Road and on the East Croydon to Wimbledon line.<\/p>\n","protected":false},"excerpt":{"rendered":" Rail replacement works which VolkerRail undertook on the London Trams network earlier this year used a new track maintenance solution developed by Sika.
