Hi,
We are renovating our basement bathroom. I've chipped out the floor drain and a bit around it.
We've decided to reroute the plumbing and move a toilet among other things.
How much can we safely chip out "tracks" for new plumbing?
It's a basement floor with about 5-10cm concrete and then crushed stone/gravel/soil directly underneath. So far, I haven't encountered any reinforcement.
The house is from 1959 and it's a split-level house with load-bearing walls in concrete stone that go down about 120cm into the ground and then a footing.
I guess the basement floor was poured after the walls/framework were completed and thus has nothing to do with structural integrity, so it should just be a matter of chipping away, but I'm not sure?
See the room marked in red on the drawing.

It will be quite a lot if you look at the picture.
Green will be from the new toilet about 3m
Yellow from the shower floor drain about 3m
Red from the upstairs kitchen and sink about 3m
The two blue are from small floor drains possibly spygatter in the sauna and laundry room about 1.5 and 0.5m
The black is from the sink about 0.5m

What you need to consider is that the slab can withstand ground pressure from the outside. But this is only if you demolish along an entire wall, for example.
You can demolish as you planned without problems, partly because there are shorter distances and there are other walls that hold up.

Yep, I think I understand what you mean. I've experienced the same phenomenon when emptying large pools too quickly.
But you don't think it's an issue in our case, do you?
I was considering digging up the entire old concrete pipe and replacing it, but it might go down under the house's foundation and that doesn't feel ideal. But now we've found another more modern plastic pipe that we're going to connect.
