My friend just pulled his toilet (which was on a slab). He found that the slab floor stopped inches away from the drain pipe and the flange and ring were attached to the drain and the toilet bolted to the pipe but not to the floor.

He has asked me if the concrete should go all the way to the pipe and should the toilet bolt to the concrete subfloor?

He wants my help to install a Pergo floor, but is concerned about what he found, and whether it needs to be corrected before we install his floor.

Your thoughts and comments please.

I say it needs to be repair and made right before you go on. I would pour in some more…..maybe concrete. I have used a product called vinyl patch. It does not shrink like I am afraid a small piece of concrete might. The vinyl patch comes in 2 sizes of containers. A small tub costs almost as much as a 10 LB bag. Go for the bag and follow the directions. the work time is short. It is tough. I would want that closet ring firmly attached to the pipe and both pieces well anchored to the concrete floor.

You did not say a word about copper pipes, but if you do have copper pipes they will react with concrete and develop leaks. It would probably be easiest to follow Grandpas advice on this one. Good luck.

Best thing is to first make sure the pipe is sitting level. Then from there make sure you clean up all the lose concrete. From there you will need to get some bonding agent so the new conrete will bond to the old. Then you can pour the new conrete and set your flange. Then you can either put lagsin the concrete or drill and screw it after it is cured for several days.
