Changing 1/2 bath to 3/4...

Broke the concrete... had a plumber install the piping... covered pipes up again.

Do I just simply buy concrete, mix it, and spread it evenly?? Is it that simple? Are there tricks to it?

Thanks in advance.

Hi Ken,

If It's a small trench just cover the pipes with dirt, tamp it down and run a patch over the open hole.
If it's a large area you might want to cover the pipes with dirt, tamp it down and lay down some plastic and wire mesh before you pour concrete. Good luck, Tom

How exactly do you "tamp it down"? I've used my hand to level it. How compacted does it need to be?

It is a small trench, a little less than 1 ft. wide.

I'd just take a piece of 2 X 4 and tamp around and over the pipe so the cement doesn't sag as it's setting up. Good luck, Tom

Kaputt, it may be even easier and cleaner to use sand. Sand self settles pretty much with little tamping. Speedball's 2x4 is my best tool.

Thanks for the help guys... 1 more:

When patching the concrete, the concrete should be set up just below the toilet flange, correct? (As in the flange should be "resting on it".. )

I am assuming your plumber already set the flange when hew did the roughin. Your concrete should be level with the rest of the floor. The flange can be above the concrete surface, sitting on it. The toilet and the flange are a bit forgiving once you set the wax ring. If you feel the flange was set too low you can buy an oversize wax ring that is thicker for this situation.

Or you can purchase a set of flange extenders, (see image). Cheers, Tom
