Rail Boot

Epflex® Rail Boot isolates the rail from the surrounding roadbed. Control stray current, vibration, and noise in embedded track construction and extend the life of road surface.

Electrical resistivity provided, by the specially engineered, thermo-formed elastomer, prohibits negative impact on the adjacent utilities caused by the return current, significantly reducing maintenance costs.

Track Jacket - Isolation for Special Trackwork

Polycorp "TrackJacket"®, is a complete line of Elastomeric materials to completely isolate embedded track. An integrated system to designed to control stray current, vibration and noise in the most difficult application, special trackwork. Switches, frogs and diamonds can now be decoupled from the concrete, eliminating pinpoint loads and stress concentrations to prolong the life of the road and the track.

Removable Design

Road closure and detours are often the worst part of any urban construction. The track structure, because it is used by all modes of transport; vehicular, rail and pedestrian, sees excessive wear of crucial components. This results in repetitive construction costs, and delays and inconvenience for the motoring public.

Polycorp "Removable Design" rubber interface allows access to the rail and fastening system, without the costly road construction. Detours are avoided by doing the work in controllable portions in off service hours.


  • Maintenance scheduled in off service hours, eliminating schedule interference.
  • High rail wear areas, such as car stop locations and curves, can be quickly upgraded and improved with no system disruption.
  • The Railseal Interface doubles as the concrete forms. Exact fit is guaranteed with no extra labor costs.


Polycorp engineers pride themselves on ingenuity and as a result, we have combined many traditional technologies which resulted in the next level of innovation.

EPFLEX® Railseal / Enclosure Combination
The Epflex® Railseal/Enclosure Combination System isolates the rail from the surrounding roadbed and provides numerous benefits for both the Transit Authority and the motoring public.

Polycorp design team can provide custom materials to fit any dimensional situation. Electrical isolation is accomplished with an inner liner of boot while the bulk of the trough is filled with more commercially viable material. The result is the best of both worlds, a sophisticated system for rail isolation, track modulus control and access with an affordable price tag.

EPFLEX® Railseal / Concrete Panel Combination (CPER)
Panelized crossings allow a modular approach to system maintenance, which is preferred by many railroads and transit authorities.

Epflex Railseal absorbs all the vehicular impact to provide a “Softer”‘ ride for the motoring public while sealing the surface contaminants from the ballast. The result prolongs the life of all track components and is best suited to pedestrians and bicycles.
