Ballast Matting

Sub Ballast Matting (SBM)

Ballast matting is a decoupling mat beneath rail systems. In the railway (railroad /am.) construction it is used as sub ballast matting, and in mass spring systems it is an elastic layer. These track-bed mats reduce structure-borne noise as well as vibration emissions. The service life of the ballast matting is lengthened by lower and more even stress.
 A special mixture of rubber granulates, microcellular rubber and polyurethane foam on a recycling basis, bonded with PU-elastomer, provides the desired effects.

The advantages of the track-bed mat DAMTEC® KRAIBURG SBM can be summarized briefly:

• protection of the sensitive sealing (waterproofing) layer against damage from ballast
• reduction of structure-borne noise
- reduction of secondary air-borne noise
• protection of adjacent buildings by reduction of vibrations
• can be also used for mass spring systems
- uncomplicated installation
• extremely long service life.
