Tackling tramway vibrations

Protecting historic buildings from vibration damages in a busy city

The development of a modern cable-free tramway network has improved transportation in the Bordeaux metropolitan area considerably. The third phase of the construction work continues, including Line D which will run for 9.8 kilometres and call at 15 stations.

As Line D plays a significant part in supporting Bordeaux’s development, great importance was given to protecting the city’s historic infrastructure from vibration damage, as well as ensuring comfortable living conditions for residents near the tramway.

The joint constructors, Ingérop and Systra, chose a vibration isolation system from railway technology specialists Rockdelta, part of the ROCKWOOL Group.

Rockdelta RX anti-vibration mats reduce ground-borne vibrations and noise from floating slab track systems. And being stone wool based, not only do they protect from unwanted noise but they are exceptionally robust and have a long, maintenance-free life which will reduce costs.

Because traffic had to be stopped to allow for construction, fast installation was imperative for this project. Fortunately, Rockdelta mats are easy to handle and very quick to cut into different sizes and shapes, which helped keep this busy city moving.

Using Rockdelta mats has protected the city’s rail-side buildings from vibration damages for the long-term, and has given residents complete peace of mind. It’s an example of how the use of stone wool can overcome complex transportation challenges and contribute to a quieter and more sustainable future.
