Anti vibration

Ballast Mat Damper

The Railmat Ballast Damper is an antivibrating mat in recycled rubber that is installed under ballasted tracks. It reduces vibration level of the ballasted track in urban areas (up to -20 dB @ 63 Hz).

Antivibrating mat

The Ballast Mat Damper produced by RubberGreen is a mat made from natural recycled rubber. Natural rubber gives optimal properties for resilience, anti vibration performance with a low damping factor, fatigue and longevity resistance.

It helps reducing the vibration noise of ballasted track in urban areas and/or can also increase the life cycle of the ballast. It also helps compensating reduction of the ballast thickness where it is not high enough. Finally it helps reducing impact force that structures may experience over time (such as Bridges).

The Ballast Mat Damper is suited for tramways or subways as well as for train lines in urban areas.

Thicknesses, shapes and densities

The Ballast Mat Damper is available in different thicknesses, shapes and densities in order to address expected performances : low density and wavy shape for vibration insulation, higher density and flat shape for impact force reduction on structures.

A geotextile membrane on top of the ballast mat damper is required in order to optimise product lifespan. It increases the resistance against ballast stresses and it protects the mat against dust from ballast wear.

The Ballast Mat Damper product range is compliant to DIN 45673-5 and EN 17282.
