Resilient Calenberg ballast mats and track elastomers that protect structures and cut structure-borne vibration and noise on bridges, in tunnels and near sensitive buildings, with the Ciprotec 6018 and 2022 systems supplied most.
Calenberg Ingenieure (a LISEGA Group company) develops track elastomers that reduce noise and vibration from rail traffic: ballast mats, elastic rail pads, under-sleeper and sub-ballast mats, and related products. They protect people and buildings in the living and working environment along the line.
The Ciprotec under-ballast mats are the core of the range. The two Kampa supplies most each carry a Certificate of Compliance to specification SPC00061: Ciprotec 6018 (Type A), which protects the concrete or steel structure and the ballast under the track, and Ciprotec 2022 (Type B), which reduces structure-borne vibration and noise. Both are laid under the ballast on bridge decks and tunnel floors and fully cover the subfloor.
The mats are made of 100% recyclable elastomer with a geotextile cover, from 13 mm thick, and are matched to the axle load, speed and track type. They meet DIN 45673-5 and EN 17282. The wider range is documented below: rail pads, mass-spring and under-sleeper systems, Cisilent sound insulation and OilEx environmental protection.
Benefits
The two ballast mats Kampa supplies and installs most, each certified to the SPC00061 specification by DEKRA Rail, as Type A and Type B for their stiffness class.
Laid under the ballast on bridge decks and tunnel floors, and on sections near vibration- or noise-sensitive buildings. Suitable for tram, light rail, metro, freight, conventional and high-speed lines.
The mats cut structure-borne vibration and noise, reduce dynamic wheel forces, stabilise the track and protect both the ballast and the structure, which lowers maintenance.
Double-layer mats of 100% recyclable elastomer with a geotextile cover, from 13 mm thick, to DIN 45673-5 and EN 17282.
The range
The most-used Ciprotec mat: a double-layer elastomer mat laid under the ballast on bridge decks and tunnel floors to protect the concrete or steel structure and prevent ballast wear. Certified to SPC00061 (Type A). Datasheet and certificate below.
Most supplied by Kampa.
The Ciprotec ballast mat for vibration isolation: a softer bedding to SPC00061 (Type B) that reduces structure-borne vibration and noise from rail traffic, for sections near sensitive buildings. Certificate below.
Most supplied by Kampa.
Rail pads and base-plate pads that tune the resilience under the rail, for high-speed and conventional track.
Flexible sound insulation for indoor and outdoor use.
Elastomer protection that keeps oil and pollutants out of the ground in transport and industrial areas.
