Continuous rail support
edilon)(sedra Corkelast® ERS (Embedded Rail System) is a high-quality rail fastening system for Heavy Rail, Light Rail and tramway applications based on embedded rail technology. The system derives its durability from continuous rail support and very high stray current reduction, among other things.
The rail is elastically fixed in a concrete or steel channel by means of the two-component elastomer edilon)(sedra Corkelast® and supported by a rail strip from the edilon)(sedra Trackelast® product group. After hardening the Corkelast® remains slightly elastic, but very tough, thereby creating a stable and durable rail bond.
Corkelast® ERS provides a uniform transfer of forces from the rail to the supporting environment. The system addresses forces and tension caused by passing rail and road traffic and physical influences such as temperature changes.
edilon)(sedra is both pioneer and global leader in embedded rail track for more than 50 years. The Corkelast® ERS is fully proven and conforms with CEN 13481-5.

A key feature that sets ERS apart is its innovative approach of encapsulating and
bonding rails using the high-performance two-component edilon)(sedra Corkelast®
embedding compound within a concrete- or steel channel. This unique, long-life
material ensures a homogeneous and continuously support of the rails, with
specifically determined elasticity, in accordance with specified project conditions.
ERS system designs are tailored to meet a wide range of vibration damping requirements.
Whether it's ensuring the highest standards of performance near acoustic sensitive structures
or demanding urban environments, we've got you covered.

From custom filler blocks to PVC cable routing solutions (refer to the image
on the left), ERS stands for versatility and flexibility.
Corkelast® ERS offers a quick installation process especially when using
prefabricated concrete or steel channels. ERS offers a particularly low
installation height (which is especially advantageous on bridge and
elevated track structures), is compatible in alignment and can be easily
integrated into various finishing layers such as asphalt, concrete, grass
or cobblestones.
Why opt for Corkelast® ERS
- Rail life extension through continuous support
- High degree of stray current reduction
- Excellent vibration damping, adjustable elasticity
- Virtually maintenance-free and therefore optimum track availability
- Low construction height and weight and therefore ideal for (integral design) applications in tunnels and bridges
- No obstacles and thus accessible for fire, ambulance or cleaning services in tunnels or on bridges, for example
- Highly resistant to flooding
Advanced Urban Slab Track System
Corkelast® ERS is an integral part of the edilon)(sedra USTS (Urban Slab Track System). The system has a wide variety of application areas. It can be applied using “in situ” poured concrete, as well as easy-to-install concrete slabs that are custom designed and manufactured. These slabs are also suitable for track applications such as switches. A steel-channel-based construction method is also available.
Continuous rail support is provided by Corkelast® ERS. Combined with stable positioning, this ensures optimal track operation and availability. In the end, it’s all about the safety and comfort of the traveler!
edilon)(sedra Corkelast® LCS-350
NEXT GENERATION Level Crossing System
The edilon)(sedra Corkelast® LCS-350 Level Crossing System is developed according to the highest safety standards. The system is based on prefabricated concrete slabs, combined with edilon)(sedra Corkelast® ERS (Embedded Rail System) for rail fastening.
The continuous rail support strongly reduces peak loading associated with ballasted track based level crossing systems. Corkelast® LCS-350 level crossings allow for years of maintenance-free service.
The most economical solution!
- Strong system resistance to traffic impact forces, even with extreme road angles
- Prevention of water ingress effects
- Very high stray current protection
- Suitable for all kinds of track alignments including canted and sloped track
- Minimum maintenance for optimal track availability
The rail is bonded with the 2 component edilon)(sedra Corkelast®
elastic embedding compound, resulting in:
– Avoidance of water ingress effects
– Very high performing stray current protection
– Increased rail life due to the continuous rail support
– Prefabricated and reinforced concrete slab
– Superb rail/road interface > S-shaped roads, roundabouts, curved roads
– Slabs can be tapered upon demand to accommodate for curved track
– Quick and easy to install
The ideal system for conquering even the toughest
heavy loads and forces with ease.
