Managing under rail assets has challenges that are unique. Recent increases in axle loadings of freight trains across Australia has seen the design loading on under rail culverts and structures pushed to its limit.
A combination of age and harsh conditions means that many of these under rail culverts and structures are approaching the end of their practical life and threatening the assets delivery capabilities and more importantly their safety. In many situations it’s not practical to undertake a complete shutdown of the rail line to excavate and replace the culverts and stormwater pipes which is why a trenchless solution is the preferred option.
Downer PipeTech specialise in the installation of stand-alone structural linings of culverts & structures that provide a solution with up to 100 year design life. All liner installations are done whilst allowing the rail line to remain in service and functional during the remediation and repair.
