sorry about the rant, but it just really pisses me off when guys tro to invent these half ass repairs. It would take me about 4 hours by myself to rip out the mud bed and replace it with a new one. That's including packing all the materials in and out of the house. I bet you they've already spent half that time scratching their nuts and trying to come up with a plan.

I think those rants sound even better with your accent, Petr.

Don't be gone too long, eh?

Update

The builder representative said this repair will work. He has had it done in the past. He also informed me that he is responsible for having the floor fixed. Any third party input is interesting but ultimately the builder is warrantying the work. In an extremely nice way he is basically saying: we are here, we are the experts, this is what we need to do to resolve the problem any other fix will be at my (the home owner's) expense.
While talking to the builder representative, I found out that a pre-slope mud layer was not used. The shower floor was installed using another process. One question I did not think of while talking to the representative, since the bed liner lies directly on the post tension concrete floor, and we changed from a pebble floor to a tiled floor can there be a problem? The pebble floor with all the grout will dry out quickly; while the 3" X 3" tiles will have less grout but the tiles themselves will allow less water to penetrate to the sloped mud layer below. Any comment?

Makes no difference, Paul. Without a pre-sloped bed of mud under the liner, the shower won't dry properly anyway.

He's not a expert Paul, if he was he would know to put a preslope under the liner. That's shower building 101. All he's building for you is a big petri dish. Water will just sit on top of the liner with no where to go just like Kman said. The smell will let you know the pan has completely filled up with water.

Paul,

Insist on a new shower from the floor up. Refer your builder to the International Plumbing Code section 417.5.2 (https://codes.iccsafe.org/public/doc...de/550/9793343) which says in part:
Quote:
Liners shall be pitched one-fourth unit vertical in 12 units horizontal (2 percent slope)
There is similar language in the Uniform Plumbing Code, if that is the plumbing code used in your area, I believe the section is 408.7.

Cheers, Wayne

Some inspectors only look for a waterproof liner. As stated, CODE requires it to be sloped. Neither tile nor grout is considered the waterproofing layer...it is a decorative, wear surface...not waterproofing. I find it sacrilege that some inspectors only look for waterproof and do not enforce the slope requirement.

The TCNA handbook is the industry bible on how to construct anything with tile (including showers). It appears what's there does not follow any one of those available methods. It's all about the details...fail one step, and it usually results in problems.

Paul, I hope he gave you the wink, wink when he said that he's the expert. I'm with the others, this is a joke. They're trying to half ass it and get you out of their hair.

First, I would like to thank all those who have commented; I have learned a great deal. The builder's representative had contacted the tile contractor who said a pre-slope was used. So that is good. The plan is still the same. Dig out the center section of the tile floor from one side to the other in a "V" shade around the crack. I believe they are going down to the liner but not sure. Then install a new drain with weep holes followed by mud, level and smooth mud following the slope, then allow to dry and tile. Hoping for the best.

Then you'll have two cold joints in the mud floor.

I don't understand why they can't just do it right this time and be done with it. Taking out the entire floor to the liner is the best option for long-term success.

Hi Kman

I believe they are concerned that since the shower floor is 3' x 7' they have a greater chance of damaging the liner. In addition, they supposedly done this before with no problems.

Well one would think that since they've "done this before" in regards to the fix, they'd stop screwing up the initial installation in the first place.
