Breaking up the slab?

[cikada]

Hello!
Is it possible to cut/open the foundation slab to install a new sewer pipe?
How would one go about doing that?
The slab has reinforcement and waterborne heating coils.
Thanks in advance.
Best regards,
cikada

It probably depends on that.
Are the heating coils embedded?
Do you know where the coils are if they are embedded?

Otherwise, there are no technical problems with opening the slab except that it causes a lot of hassle. The restoration work can be EXPENSIVE!

Possibly, it might be possible to press/drill a pipe from a pit beside the house under the slab to the place where the shaft comes up.
There are specific firms that deal with such things.
Whether it is possible depends, among other things, on what kind of soil is under the house.

the underfloor heating is embedded. I hope that they know where it is, if not, maybe there are instruments to find them??
I also have a post under law:
rights in case of faulty foundation
...with more info and a few more posts. The expensive part will be covered by the house company. I mostly wanted to do research so I know what I'm talking about when I bring it up with the house seller and contractor. They, of course, do not want to break it up..

check the post for more info

If you run hot water through the loops, a thermal camera should be able to see where they are....

Ugh and yuck for having to zigzag between heating coils with a snowplow
