looking for suggestions on how to best remedy this..

[Sgt Beavis]

As stated in the "jetted tub" thread, I am remodeling the master bathroom.

Today I demolished the shower so I could re-tile it. Basically it was a cluster fuck.

The builder did use green dry wall behind the tile but he nailed that on top of regular paper lined dry wall. Over time, the grout on the tile was penetrated by water. That water then penetrated the paper lined drywall. Of course this got moldy. I spent a few hours pulling that apart.

However, after removing all the drywall, I found that a rat had made its home under the shower pan and my garden tub. After cleaning up some more, I found where the rat had been coming in.

It looks like the builder ran a sewer vent from the foundation to the wall. To do this, they cut away the base plate for the wall. This, left a nice hole for anything to crawl threw. There was rat shit everywhere. I'll spare you a picture of the mess, but you can see what the builder has done. I also noticed that the outer sheeting isn't nailed down to the base plate. That is easy to fix. However I'm trying to figure out the best way effectively close up that hole. Any suggestions?

Here are some other pictures of the cluster fuck I had to deal with.


This is the shower drain. Notice the big ass hole in my foundation? The just covered this with the shower pan. Fortunately, it is an easy fix. I'm planning to put down a tile shower floor, THE RIGHT WAY, so I'll have to properly patch this hole. No biggie, I can deal with this.

This is the moldy, paper based, dry wall that was under the green board.

This is what the insulation looked like. The rat tore it up like that.

So now I need insulation, hardi board, some concrete, bit of rebar, a rubber liner for the shower pan, new drain, mortar for the tile bed, etc, etc, etc,...

First thing is that tile/grout are not "water proof" and that water will come through.

The other thing is that you need to call your insurance co and let them write you a check. They will not cover the pan that failed, but all the rock and tile work should be covered. Depending on your deductable, you might have a decent check due.

Oh, and great stuff that hole.

Are the two studs moldy? If it was me, I would replace those while you are there if they are. I like to start as fresh as possible.

No, they are still in good shape..

[Tj02]

builders do everything as cheaply as possible.

[onjacks]

Make sure you "pre-slope" your showerpan. And, don't forget to put plastic sheeting on the studs before you install the hardie backerboard.

I tear out this kind of crap all the time. Lol.

[FreightTrain]

Just fill the hole with tar. Seriously thats what your suppose to do and they sell a special kind of tar to use. What ever you do be sure to wear gloves when your dealing with the stuff and prepare to throw away every tool that comes in contact with it.

I'll look into that.

thx

WOW!!!

Be sure to spray all the plywood and studs with some Kilz. Also i would use durarock instead. That whole fucking sux dude.




<MILK

[milk]

As far as the rat spray some of that Great Stuff in there. LOL!!!

[ceyko]

Yeah, I'd use the "great stuff" where ever possible too.

[centexchick]

I can believe all of that. We dealt with some of the similar stuff when we tore into our master bath (no rats, but the rest of it). You look about at the same point as we are with the fixes. Ughhhh....not fun at all.

[Sgt Beavis]

I've nailed down the outer sheeting and filled the gaps with Great Stuff. I'm going to let that set/expand then install the new installation.

I've got to investigate onjacks suggestions of putting plastic sheeting under the hardi board.

I'll also milk's Durarock suggestion. I've always liked Hardi board because it is basically cement but I've never looked into Durarock.



Ok, so about that big ass hole in my foundation. I want to put down a tile shower pan. I know how to do that PROPERLY. The question here is what should I use to fill the hole. I has to hold up well to expansion and adhere to the existing foundation.

I was thinking of using a Vinyl Cement Patch as mentioned in this link:
http://www.usehickson.com/StoneMason/ConcreteRepair/VinylCementPatch.shtml

It is pretty easy to use and should adhere well. I will be putting a new drain on with a proper vinyl shower pan liner. I'll be going to the whole fuckin' nine yards to get it right...

Do you think that vinyl cement patch should do the trick?

Your missing the point. That hole is suppose to be there because anytime you have a shower or a Tub your going to have to put the P Trap under them. You don't want a P trap in 6inches of concrete because if you ever have a problem your going to have to bust out the concrete to get to the P trap. The builder is suppose to install whats called a tub box and fill it with tar. Unfortunately most builders build a box out of 2x4 and remove the 2x4 when the foundation is cured and never fill it with tar because that cost them an extra 20 bucks. The point of filling the open space with tar is that it keeps moisture, bugs, and other shit from coming up under your foundation into your house.

Here is a link showing what a tub box is but since you already have a hole just file it with tar. Trust me I'm not bull shitting you. Before I was a railroader I did plumbing.

Ok, let's say I go that route.

Can I mortar over that tar to build the tile shower pan for my shower?

Thanks

I had a suggestion from a buddy in Louisiana that is a plumber. He said that he has seen situations where the Ptrap has been covered with packed sand. Then a THIN (about half of what the foundation would normally be) layer of concrete poured over that. Then he was able to pour his mortar bed for the shower pan over that.

Does that make sense. It keeps the P trap from being encased on concrete but allows a solid surface to build on..

I'm not going to start on this until Saturday, so I've still got some time to think this through..

Yeah in theory that would work also. I just don't want to see someone fill those hole with concrete because your asking for problems down the road and a plumber is goind to charge out the ass if he has to bust up concrete to get to a P trap. Also I think if the insurance company saw concrete covering a tub box they'd pull the plug on it not to mention thats against code. The tar will really suprise you though. That stuff gets pretty damn hard when it sets up just not as hard as concrete.

I also think you should contact your insurance company. When I did plumbing all we dealt with was insurance claims regarding water leaks that caused mold to grow and the insurance companies would pay out like a slot machine. From the pictures it looks like you'd have yourself a pretty decent claim.

I have seen your other thread for after you have laid your tile.....what did you do here? Did you just fill with tar or did you do this route? We took out tub out this weekend and this is what we found. I really want a claw foot tub so that the tile goes under the tub to the wall. It might work to go the route your plumber friend mentioned; I am just not sure if the other will work.

Thanks!
