ᐅ Protection sleeve for underfloor heating pipes missing in the area of movement joints

In the course of dealing with the issue of the movement joints with my floor installer, I have now identified a defect (in my opinion).

In the area of the movement joints in the dining and kitchen areas (L-shaped room), it appears that the protective conduit around the connection and pipe of the underfloor heating was forgotten. According to the underfloor heating manufacturer and probably several standards, the underfloor heating pipes crossing the movement joints should be fitted with a 30cm (12 inch) protective conduit.

I have already had this issue recorded in the defect report as a precaution and requested feedback on it.

Now I’m wondering how serious this issue is or could become.

I hardly believe the screed installer will replace the screed to add a protective conduit around the pipes. I think it’s more likely that an extension of the warranty will need to be discussed (my preferred option), or financial compensation (which the general contractor will probably prefer, perhaps offering around $500). But how should this be assessed? Or should I already consider hiring an expert or appraiser?

Who is the manufacturer of your underfloor heating pipes? The technical documentation provides the correct installation guidelines.

As far as I understand, these are Viessmann pipes...

This is what I found...

The designation is printed directly on the pipes and can be checked in the heating system manual (HKV). With that and the installation guidelines, you have everything clearly documented in writing.

The manufacturer of the underfloor heating components for my project is Schütz, as stated in the manual. The site manager just called and requested photos from me showing the heating circuits. These will now likely be reviewed by the general contractor’s technical manager and the screed installer. However, according to the phone conversation, usually nothing happens in such cases.

Yes, of course, usually nothing happens. But the installation instructions are not given without reason.

As I said, I won’t be satisfied with such dismissive answers. But I find it shocking that it seems common practice to forget such a simple protective conduit, which for a 50-meter (165-foot) coil probably costs only around 20€.
