The SL-Deck is an innovative precast concrete slab invented and developed by Abeo based on a new technology originating from the Technical University of Denmark. The slab combines self-compacting concrete with light-aggregate concrete, which gives a light and very flexible slab capable of handling long spans in addition to being cheap to produce, transport and install.
The SL-Deck has been developed based on feedback from +50 building construction and engineering companies. Following a 3-year R&D and testing phase, the SL-Deck was first brought to the Danish market by Abeo in 2014.
During 2014 and 2015, the SL-Deck was sold to the first series of building projects and has since been used in a wide range of building projects within both the residential, commercial and public sector.
Concrete slabs can generally be divided into 3 groups:
Prefabricated concrete slabs
In-situ casted slabs
Half slabs like filigree/wide slabs (50% precast and 50% in-situ).
Up until today, a contractor’s choice between these slab systems has typically been a choice between either high flexibility (in-situ and filigree) or fast and cost-efficient installation (precast).
The SL-Deck offers contractors the flexibility of in-situ cast structures at the speed, quality, and cost of a 100% precast concrete slab.
The SL-deck thus closes the market gap, which has developed over the years due to the introduction of stricter building codes, more challenging architecture and complex building designs.
Among the benfits of the SL-Deck are:
High level of flexibility and possibility of making cast-in solutions (reducing on-site processes)
Low weight and cheap transportation
Larger spans and up to 3.6-meter width (quicker installation and lower crane costs)
High level of sound insulation and fire resistance
Ultimately, making it possible for contractors to reduce construction time and costs.
