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?

Firstly: Maybe because it wasn’t done properly?

Secondly: Should one accept this as a learning cost to ensure it is done correctly in the future?

Thirdly: I would be satisfied with a written confirmation stating that nothing can or will happen due to the missing protective conduit, or that in case something does happen, an extended warranty applies.

If someone has the guts to claim that nothing will happen, they should also have the guts to take responsibility and stand behind it if something does go wrong.

@wrobel Just a trial! That was a rough estimate.

Hey,

can someone please explain to me what the purpose of the protective conduits is and what to watch out for to ensure they are properly installed?

The plumbing company is currently working and is expected to finish by the end of next week. The screed is scheduled to be laid sometime after March 9th.

Thank you!

DIN 18560 Part 2, if I’m not mistaken, you can simply look it up.

For movement joints that may only be crossed by connecting pipes, protective sleeves with a minimum length of 300mm (12 inches) must be provided.

This is similarly stated in the installation instructions of underfloor heating manufacturers and some technical bulletins. These describe how to design movement joints, and the protective sleeves are also mentioned there.
