edilon)(sedra Corkelast® EBS for METRO VIADUCTS

edilon)(sedra Corkelast® EBS (Embedded Block System), a ballast free rail track system, that consists of concrete monolithic blocks that support running rails. The concrete blocks are elastically embedded into pre-cast concrete trays that are cast permanently into the slab track. This bonding also forms a seal to prevent the ingress of liquids and detritus that may cause problems for ordinary ‘booted’ block systems.

  • Tuned vibration attenuation “mass-spring-system”
  • Savings in construction height & weight
  • Adaptable positioning of drainage and signalling cables
  • Omission of reinforcement in the track concrete
  • Fast, simple and accurate installation methods
  • Considerable reduction of ground/structure borne noise
  • Sustainable track geometry
  • Optimum electrical isolation
