Vibration isolation mats
Vibration-insulating under ballast mats are designed for use in tracks (railway, tram and metro) to reduce the dynamic effects of rolling-stock traffic on the surroundings of their routes. The reduction in impact includes the damping of vibrations (material vibrations) and noise – primarily the so-called secondary noise emitted by the vibration-induced structure elements of buildings and engineering structures during the passage of a rolling-stock.

UNDER BALLAST MATS:
Under ballast mats – often referred to by the acronyms UBM and/or SBM (Under Ballast Mats or Sub Ballast Mats, respectively) – are designed for ballasted track superstructures to be laid on the substrate beneath the ballast layer. Under Ballast Mats are particularly effective on rigid substrates such as concrete tunnel bottoms, concrete or steel ballast troughs on a bridge structure. In addition, UBM/SBM mats, by increasing the contact area at the interface between the subgrade and ballast layer, reduce the stresses in the subgrade and ballast by slowing the rate of crushing of the ballast grains.
UNDER SLAB MATS:
Under Slab Mats – often referred to by the acronyms USM and/or STM and/or MSS (Under Slab Mats, Slab Track Mats and Mass Spring System, respectively) – are designed for ballastless track superstructures. They are installed, for example, under a concrete substructure slab, a longitudinal beams under a track grate. USM/STM/MSS mats are typically used to reduce the impact of the track on the surrounding area by reducing the vibrations generated during the passage of rolling-stock and thus reducing the secondary noise emitted by the excited structural elements of structures located next to the track.
Polyurethane composite (secondary polyurethane) PUR
EPUMAT PU vibration-insulating mats made of polyurethane composite material are intended for use on ballastless tracks to reduce the dynamic effects of rolling-stock traffic on the environment surrounding the track. The reduction in impacts concerns vibrations (material vibrations) and noise – primarily the so-called secondary noise emitted by vibration-induced elements of the construction of buildings and civil engineering structures.
