Sub-ballast mat G 1000 Series - Why choosing this product line?


The USM G 1000 sub-ballast mat isolates and protects the subsoil of e.g. bridges and tunnel structures within the track system. The ballast is also effectively protected against wear. In addition to uncomplicated installation, the sub-ballast mat is well suited to mitigate vibration emissions. By using the USM G 1000 series, structure-borne and secondary airborne noise are reduced.

The USM G 1000 series consists of an inner insulating layer of bonded rubber granules, which is covered on all sides by a reinforced solid rubber top layer.

This solid rubber top layer gives the USM G 1000 series the following advantages:
  • reinforcement with synthetic and non-rotting fabric material – protects the isolation layer and subsoil from mechanical damage,
  • wear resistant – no abrasion of the surface
  • waterproof – no water gets inside the mat
  • weather resistant – no premature aging due to ozone or temperature


This ensures a long life for sub ballast mats of the USM G 1000 series. Various mat stiffnesses cover different permanent way requirements.
