Rail Grout

voestalpine Nortrak introduces High Performance Rail Grout HRPG® TYPE 1 and TYPE 2 MD (Meter Dispensed) along with P480 and POLYPRIME.

HRPG® TYPE 1 and TYPE 2 MD are polyurethane systems designed to fill space between transportation rail and concrete. It minimizes rail deflection, absorbs vibrations without cracking, and electrically isolates the rail. HRPG® TYPE 1 and TYPE 2 MD is delivered in meter-ready totes, drums, or pails and can be applied directly over a gravel extender for Type 1 and over a gravel filler for Type 2.
