LRT Elastomeric Grout

Northwest Rubber Extruders' LRT elastomeric grout is a special, two-component formulation made with fast-setting, return to service polyurethane. This railroad tie installation grout is specifically designed for use in rail applications to fill the spaces between transportation rail structures and adjacent concrete.

LRT elastomeric grout provides electrical isolation for electrically-powered light rail and street car tracks. It also absorbs vibration to prevent cracking and damage, and reduces noise caused by rail traffic. The vibration control feature of LRT elastomeric grout helps reduce noise levels usually associated with commuter trains.

LRT Elastomeric Grout Advantages

Elastomeric Grout is specially designed for light rail applications. The three component system consists of a two component polymer and aggregate that imparts vibration and sound dampening properties combined with exceptional electrical resistance. This product is formulated for placements that require good flow and adhesion to both rail and concrete, while maintaining line and grade. Elastomeric Grout is a solvent-free system that provides rapid cure and superior chemical resistance to a variety of chemicals including oils, fuels, acids, caustics and solvents. LRT elastomeric grout is also environmentally friendly and easy to use.
