running plumbing through slab


a little nervous to try this, the slap is suspended, a foot thick in most areas can i run a tub and shower drain through a maybe 4x4 inch deep trench then fill in, or will the slab crack or buckle, the run is about 9 feet, no crawl underneath only a few inches, any advise would be appreciated before i try this, thanks jd

I would not want to jackhammer or diamondsaw out a groove or channel or trench that size within the concrete slab.

It would require some engineering to figure out whether the slab could still withstand the stresses and loads it is expected to should such a trench be carved out.

OT: My uncle had a hole (about 18 inches square) cut through a floor slab to get at a pipe leaking down below but, heck, the house was over 50 years old. (Ultimately a new pipe was strung overhead rather than fix the existing broken pipe.)

What is a suspended slab? Do you possibly mean a floating slab?
