A new production concept – MultiSlab – developed by Abeo and Elematic, allows hollow-core producers to also use their existing casting beds for production of prestressed SL-decks. An SL-deck is a flexible and light precast slab targeted at the residential market. The slab can handle long spans and built-in value-adding solutions such as bathroom installations and floor heating pipes. The Finnish precast producer, Lujabetoni, is currently implementing the first MultiSlab production system for launch of the SL-Deck to the Finnish market at the start of 2018.
