GNEE under sleeper pads are a range of railway track vibration insulation pads that improves the life of ballast tracks and reduces the amount of vibration pollution into the local environment.
The GNEE under sleeper pads are applied directly under the sleeper of the track on both ballast and concrete platform applications. The pads can be glued on to the base and sides of the sleeper or they can be placed during the casting of the sleeper in the concrete.
GNEE has an innovative structure of high density SBR and or EPDM rubber granules and fibres which gives the sleeper pads excellent insulating capacity and provides good mechanical protection of the ballast gravel. GNEE can be used with excellent environmental insulating results on tramways and underground rail systems, on rail freight transport and/or high-speed railways.

GNEE sleeper pads for track systems on ballast are mostly used for conventional lines and high-speed lines. They perform the dual role of protecting the ballast, increasing its useful life, and reducing vibrations, thanks to their intrinsic vibration damping properties.
GNEE sleeper pads for track systems made from reinforced concrete slabs are products with mechanical vibration-damping properties. The reinforced concrete sleeper is covered with GNEE panels in order to completely protect the sleeper from the surrounding concrete.
GNEE bi-block solutions for sleepers are mostly used for conventional railway lines and for underground railway track systems. The flexible elements are applied to the resting surface of the Bi-Block sleepers inside the rubber shoe that encloses the individual sleeper block.
GNEE pads are available in a range of thicknesses from 6mm to 20mm.
GNEE RAIL provides exceptional elastic rail pads of various types for high-speed railways, normal-speed railways, and cranes. Especially the rail pads made of rubber, EVA, TPEE, and HDPE are very popular with customers.
