Hello all,
I am redoing a shower in my house that was built here in central Florida in 1995. The builder put the tile right on the drywall and now everything is rotten. So I'm to the point where I started ripping up the floor tile with a rotary hammer drill.
Problem... The concrete is very wet and crumbling, the thin set is hard but not the concrete below. thoughts?

Thank you.

The pan is flooded and the concrete is shot----How to build a shower - Building a shower pan with pre-sloped mortar bed, liner and curb.

Often the preslope is missing--causing the liner to hold water and soak the concrete bed---you will be breaking out that pan and rebuilding it----

Are you on a slab or wood framed floor?

Thanks! I'm on a slab

 

[ldouble619]

Any tips on repairing? Never done this before. There should be plastic liner below this crap?

Thank you!

If you are on a slab---consider a surface membrane like Schluter Kerdi or Hydroban by Latacrete--

With a surface membrane you would replace the pitched floor without a membrane under it---then waterproof the walls and floor with the surface membrane----great for your situation.

Time for bed here---do a google search---other members will help---I'll check in in the morning---

Check out You Tube there's all kinds of videos on how to build a shower pan.

You have a mess. But you have the rite tool for the job in the electric hammer. I would recommend continuing and starting from scratch. Go with the Schluter Styrofoam shower pan system. I would also recommend steel toe work boots not the flippers on your feet in last pic.:laughing: It looks like continual leaking over years caused the problem.

All you see is a big mess, all we see is dollar signs.
Love it it when people skip all the steps that would have cost almost nothing to do but would have made it last 20 more years.

Thanks for the replies. I have all the tile up and the the ground has dried.

What are my next steps for repair? Can just put the Schluter Kerdi or Ditra membrane down?

Thanks for the help.

i would replace the rotted wood first.

Thats on the list..

And to top this nightmare off... polybutylene.


We bought this house in May, do we have any recourse? This **** was covered up with plaster and new paint (the rotting corners were growing mushrooms).

What are you saying - continual leaking has disintegrated work boots into flippers?

 

[jeffnc]

I would definitely replace the PB pipe with PEX while I'm in there, because those joints are probably a leak waiting to happen.

Ditra is for floors, not showers (walls or bottom). If you use Kerdi on the walls, then you can just build the walls with drywall again (safely this time, since they can no longer get wet.)

If you mean recourse for the polybutylene, I don't think so. Check with your local building codes office, but as far as I know it's not illegal to have in a house and should pass inspection. It was never illegal or against code to use. The problems were with the original crimped joints, so when generation 2 of the joints came out it was still fine. Perhaps there's a problem with using Generation 1 joints on new construction, but I assume they would be hard to find and not used (they would have had to have been stockpiled somewhere with the intent of using them in the future to screw someone :huh: )
