The rails on which trams run must be isolated from their plinths by means of a filler block system so at to avoid the propagation of static electricity and the external transmission of vibratory waves. This reduces as much as possible the noise pollution that might otherwise be observed by local residents. The parts made from Technigom and the polyurethane binding agent make it possible to perfectly satisfy these significant technical constraints.
