Installation is quick and the Z-bloc is easy to move and reset if necessary for any reason e.g. track maintenance or resiteing.
The active sound absorbing material in the Z-bloc is comprised mainly of used car tyres. This recycling feature means that the more the Z-bloc is utilised the more the rapidly growing problem of used car tyre waste is reduced.
Christina Ortliden,
Technical responsibility for Swedish dept of railworks:
"The Z-bloc not only meets the demands of effective noise muffl ing, but thanks to its design it also blends into the environment. No extensive construction work is required for installation of these blocks. They are easy to handle when carrying out rail maintenance and are also ideally suited as temporary noise barriers for building operations."
