Proven solution for challenging projects
The use of stone wool for vibration control and structure protection in railways may seem relatively new or even counterintuitive. However, they have been successfully used to control ground-borne vibrations on railways in some of the harshest conditions in Scandinavia since the early 1970s. Rockdelta® stone wool mats are backed by over 80 years of experience in stone wool production and over 43 years of expertise in vibration control solutions. Today stone wool is the preferred solution for rail track vibration control and structure protection in Scandinavia and many other countries across the globe.

Vibration control: protecting people and buildings from harmful vibration
Rockdelta tackles vibrations annoyance by isolating the track and protecting nearby structures from ground-borne vibrations caused by rail transport systems: tramways, light rail systems, subways, metros, main lines and high-speed lines. Attenuation of vibration is achieved by decoupling the track from the surrounding environment using Rockdelta as a resilient mat.
Ballast and Subgrade protection: reducing ballast attrition and protecting the substructure by decoupling the ballast bed
Rockdelta mats may be used as well for decoupling the permanent way from the railroad formation to reduce ballast attrition, prolong the life of the ballast bed and limit maintenance activities by improving the distribution of the acting dynamic forces in traditional ballasted railways and bridges.
Rockdelta applications: the natural solution for every track
Rockdelta mats are designed, tested and manufactured to have an extended lifetime with retained functional performance even under extreme conditions. This helps ensure the exceptional long product life cycle of Rockdelta mats.
