Cut on grade concrete to install tub drains. Can this be right? Seems excessive…

It is generally necessary to cut completely through the slab to install drain lines. Whether he needed to tear out so much concrete is hard to say, without more info.
(Kinda late to be worrying about it.)
(But concrete slabs don't keep out groundwater.)
Yes, the amount of cutting was my concern....
Yes, I understand that the concrete must be cut all the way through, the amount of cutting was my concern.... I would expect a channel or two, just not the entire floor.
Can anyone tell me what steps should be taken to repair the concrete and prepare it for flooring once the plumbing work is finished?
Tamp the sand in as you backfill the hole, place the new concrete in and trowel it smooth. No big deal. I am sure your plumber does it quite regularly if he does remodels.
(for folks not in florida the "dirt" is sand here)
OK, now I've decided to bring in 6 yards of concrete....
OK, now I've decided to bring in 6 yards of concrete to fill the 6 X 9 hole & fill the 20 x 20 garage floor to level while I'm at it. (+4"). Truck comes Saturday & I have tile on existing garage floor with 1x5" baseboards.
Should these baseboards be removed first and replaced with 1x4" PRESSURE TREATED wood?
Can simply breaking up the tile before pouring or must it all be removed? Or should I leave tile and use bonding agent?
Also, concrete company recommended 3000psi WITH a fiber additive.... Any thoughts or feedback?
If one were really obsessive the old concrete could be dowelled to the new.
Looks right to me. I remodeled both of my bathrooms and cut through the floor twice in one (sink drain and tub drain) and took out about half the floor in the other.
If this is old cast iron drain pipe it might even get uglier than that. In the main bathroom, some of the pipe was shot. I am guessing excessive use of acid drain cleaner. There was a big bottle in the shed when I bought the house. I cut it back until it started looking good.
