The wide slab floor system is a proven concept in the Netherlands and has proven itself in many projects. However, the underpinning of the wide slab floor does determine the planning of the structural work and results in additional costs. BetonShell and partners took up the challenge to develop a cantilevered floor system.
The self-supporting floor system consists of a basic wide slab with cast-in-place beams on top, which is used to achieve stamp-less construction. Ultimately, the floor becomes solid to meet noise requirements in apartments. It is also possible to incorporate piping into the floor. The poured beams absorb the own weight of the entire solid floor, making the use of supports unnecessary. The absence of underpinning saves significant time in project planning, reduces construction costs and provides a lot of free working space where otherwise there would all be props.
The big advantage is that the system can be a 1-to-1 replacement for where a wide slab floor is prescribed. This allows you to apply this floor later in the process without having to change the design. In combination with hollow walls, the JumboDeck floor allows quick dry stacking (though with wet knots) and saves construction time.
The JumboDeck floor originated from a project request for a cantilevered floor at a height of 25 meters. This floor had to become a kind of bridge over an existing building where the existing building was not to be touched. BetonShell set to work on this. Together with Holcim Bouw & Infra, a test setup was built in Oudenbosch. This test floor with various options was tested for deflection, workability and execution aspects. Subsequently, the first real JumboDeck floors were delivered and easily installed on the construction site. After this first successful project, various other projects followed.
In January 2022, JumboDeck floors will be started in a large student complex with 550 apartments in Tilburg. Interested? Feel free to get in touch!
