Low weight  


The SL-Deck combines the strength of prestressed concrete with the low weight and fantastic insulation properties of light-weight concrete resulting in a light deck that can handle heavy loads and long spans.


By applying light-aggregate concrete for app. 50 % of the deck, the weight is reduced by more than 30%. This enables significant savings on both transportation and installation. Compared to solid slabs, the lower weight typically makes it possible to transport 40-45 % more m2 per truck.


Especially in building projects with high requirements for sound insulation (e.g. apartment complexes), it is possible to achieve great weight savings. In most instances, a 22 cm SL-Deck of 375 kg/m2 in combination with a relevant floor structure will be able to fulfil local sound requirements.
