The embedded rail: technical system for slab tracks

The term "Embedded Rail" commonly describes this laying track method. It involves the embedding and bonding of a rail into a concrete channel structure by means of a polymeric grout (V-Flow). The technical system can be used for slab tracks.

Benefits of embedded rail

This easy and efficient solution offers many advantages for fixing rails:
- Good adhesion to concrete and metal,
- Better damping,
- Reduction of vibration and structure-borne noise,
- Mechanical and chemical performance,
- Resistance to microorganisms
- Electrical insulation of the rail
This solution of embedded rail also reduces the structural height of bridges and tunnels.

A solution for light urban railways

V-FLOW technology has developed a range of fluid grout, elastomeric bicomponent polyurethane without solvent containing or not containing fine fillers. With such qualities such elasticity and resilient properties, the technology of embedded rail with the V-Flow perfectly meets the light urban railway track requirements : electrical insulation and reducing the structural height of track.

An easy and fast installation

After positioning the rail into the concrete reservation, the resin V FLOW 60 A is poured to fill the void under and around the rail to a thickness generally ranging between 15 and 25 mm. After 10 to 20 hours, the resin is cured.
