Tribeton® - a brand name belonging to Creabeton Materiaux AG in Switzerland – wished to change their monoblock production method from conventional to self-compacting concrete. Eltecna AG, Zürich, and Vollert Anlagenbau GmbH + Co. KG, Weinsberg, (Germany) gained the contract to develop and supply a new circulation system for manufacturing sleepers. In essence, the LVT (Low Vibration Track) monoblocks for the Gotthard base tunnel are to be manufactured with this system.
