Corkelast® EBS system

EBS basically consists of prefabricated concrete blocks that are elastically and durably fixated in a specially designed concrete tray using edilon)(sedra Corkelast®. The “block tray” combination is quick and easy to install.

This track construction system absorbs a significant portion of the mid- and high-frequency vibrations caused by wheel-rail interaction. In this way, noise emission is also greatly reduced. Not unimportant in urban areas.

Track Life Extension

with Corkelast® EBS-RF (Embedded Block System-RetroFit)

edilon)(sedra Corkelast® EBS-RF is a quick-to-install, reliable retrofit solution for worn-out “booted (bi-)block” track structures. The basis of this system consists of a block-forming concrete element with integrated elastic tray, prefabricated as a whole under controlled conditions. After removing the worn or old blocks, empty pockets are created into which the Corkelast® EBS-RF blocks can be easily and quickly installed.

Remove worn or old block
After old blocks has been removed, the existing concrete slab structure
can be utilized, which eliminates the need for any drilling or demolition,
ensuring a hassle-free installation.

Fix EBS-RF block unit to rail
The system is supplied as complete unit, ready for immediate
application and quick installation: a replacement period of just
a few hours is extremely critical to ensure the continuation of
operational traffic the next day.

Durable fixation
Ensure long-lasting stability with the rapid bonding of the new EBS-RF
unit into the existing recess using our fast-curing grout. Our experts of
the EBS competence center stays at your service for a smooth and
quick replacement process of your track - job done!

Very strong adhesion, completely waterproof!

  • Extended service life of the main track structure
  • Uses the existing concrete slab structure; no drilling or demolition of the existing slab structure is required
  • Waterproof system, maximum electrical insulation
  • Significant reduction in future maintenance costs
  • Short (overnight) replacement periods – no or limited track unavailability
