Ballast Mat

Engineered sub-ballast mats for ballast preservation and vibration isolation.

GenieMat RAIL BST ballast mats are engineered according to project requirements to provide vibration isolation and reduce ballast stress.

Due to the change in substructure stiffness, track components in bridge transition zones are subject to higher impacts and vibrations magnitudes.  

If these areas are left untreated, the track, ballast, and sleepers will suffer a shortened lifespan and increased operating costs. 

To reduce impacts in bridge transition zones, engineers use FEA to specify GenieMat BST products that will moderate the stiffer portions of track and equalize deflection throughout. 

Product Highlights

  • Engineered for transit and freight rail lines 

  • Proven to be most effective method of reducing 

  • ballast degradation 

  • Provides high-performance ground-borne vibration 

  • isolation in critical locations 

  • Water permeable for drainage 

  • Rubber or polyurethane foam

  1. Impregnable protection surface extends the contact area of the ballast to provide greater stability.

  2. Structural mesh provides monolithic reinforcement. 

  3. The resilient elastomer is engineered dependent on project conditions. 

When acoustical isolation is necessary, Pliteq offers insertion loss calculations based on the use of GenieMat BST under the specific project conditions.
