Hello,
our garage is currently at the shell construction stage. The precast concrete floor slabs are in place. I would like to lay the water and heating pipes on top of the precast slabs next. After that, there will be concrete, then 10cm (5 inches) of insulation, followed by another layer of concrete and then a screed with a slope.
Is this sufficient to keep the pipes within the concrete frost-proof?
Best regards

If the heating pipe and the radiators are continuously supplied with warm water during winter, it might work. But what about the water pipe? That will cause problems. You either need to completely drain it during winter or run it right next to the heating pipes or fit it with an additional electric trace heater. However, this can create an ideal breeding ground for bacteria, which you certainly don’t want. Also, keep in mind that insulation may still emit some heat. You will notice this in winter when snow starts to melt in those areas.
Is heating even necessary?
Is it not possible for you to install it underground?
Remember, no matter where the pipes run, if the heating fails even once during freezing temperatures, pipes in non-frost-protected areas can burst. How do you plan to fix damage to pipes embedded in your ceiling?
Make sure to drain the water pipe in winter since normally no outdoor water supply is needed then. Regarding heating, consider whether an electric fan heater could be a practical alternative.

Gartenfreund is right about that. Never fully encase pipes or cables in concrete without a good reason. If there’s a problem, you won’t be able to access them, and defects cannot be detected. It’s better to run them on top of the finished slab into the insulation or, even better, always in the heated area.
Why do you want to run pipes or cables through the garage ceiling anyway? Where are they supposed to go, and what are they supposed to heat? A drawing or floor plan would be helpful.
