Dear Colin,

When planning a project that uses precast concrete, you’ll need to make a number of choices to ensure your electrical housings are suitable. Precast concrete can help ensure high-quality end products and it is often used for projects where fast delivery is equally important, so finding an enclosure solution that complements these benefits is a priority.

Spelsberg designed the IBT range for use with both precast and cast-in-place concrete construction projects to ensure maximum reliability and efficiency. One of the most important features of enclosures of this type is their ability to prevent any concrete from entering the structure during pouring. Leakages could compromise the integrity of the components within an enclosure, so like all Spelsberg enclosures, the IBT range is tested extensively to ensure it delivers reliable protection for your vital electrical equipment.

Another point you should consider is how easy your enclosure is to install and linked to this, its ability to remain in a fixed position without moving. Insecure installation or movement after installation could cause cracks or void spaces, so you should prioritise a housing that is strong and stable to avoid introducing structural weakness.

Spelsberg’s IBT series is designed specifically to meet the challenges associated with enclosures used in precast concrete systems. The range 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. This means that you can find everything you need, no matter how complex the project.

Spelsberg’s IBT range is ideal for use in prefabricated, precast concrete panels and also cast-in-place concrete, meaning your project can benefit from high quality without specifying multiple parts from different manufacturers in mixed-use cases. The enclosures are designed to be secured to metal or wooden formwork using magnets, epoxy or nails with any required conduits connected before concrete pouring. Once set, they allow removal of the formwork to enable easy access to the face for cabling and other engineering work.

You can explore the full range of Spelsberg IBT enclosures on our website, along with full technical documentation and details of our extensive safety testing and quality assurance processes. If you have any further questions, or would like advice on any specific project details, send me a message as I would be delighted to discuss your requirements further.

Kind Regards,

Chris
