What are the best enclosure solutions for precast concrete construction projects?

A number of aspects need to be considered and accounted for when choosing electrical housings for precast concrete constructions. Firstly, the enclosures have to be resistant to leakage and prevent any ingress of concrete during pouring. Secondly, the housings should remain in a fixed position without moving. Strength and stability are also essential, so as not to compromise the integrity of the installation after the concrete has set. Finally, the electrical enclosures should be easy to install.

Currently, the only electrical housing solution specifically designed for use in precast concrete applications belongs to Spelsberg’s IBT series. The offering includes universal boxes, junction boxes, installation boxes, wall and ceiling transfers, special boxes and accessories such as sealing plugs, caps, blank bases, punch tools, cleats and support bars.

Thanks to its design, the IBT range is suitable for both prefabricated, precast concrete panels and cast-in-place concrete. The enclosures are fixed to metal or wooden formwork using magnets, epoxy or nails, and the interconnecting conduits are installed before pouring the concrete. When this is set, the formwork is taken off, and the face of the IBT housing is visible. As a result, on-site engineers can easily remove or drill through the face of the housing to gain access for cabling.

In this way, the solution from Spelsberg protects the electrical infrastructure from ingress by concrete and provides security of positioning, ease of assembly, simplicity of use on-site and a high-quality aesthetical finish.
