  • Patent number: 7337981
    Abstract: The invention relates to a vibration damping system, which comprises an anti-vibration plate in the form of a plate having a first and a second major surface, wherein the first major surface may preferably be covered with a layer of surfactant-free geotextile. The anti-vibration plate comprises one or more layers, preferably a top layer and one or more bottom layers. Furthermore, it is essential that the anti-vibration plate is preferably obtainable by a method comprising the step of subjecting an area of the opposite surfaces of the plate to a compression treatment in one or more steps, which compression treatment is sufficient to reduce the static and/or the dynamic stiffness of the plate compared to the static and/or dynamic stiffness prior to the compression. The invention also relates to the method of applying a vibration damping system and the use of a vibration damping system.
