How come two layers of durock on floor .

 

needed to match height of oak floor in next room. furring strips, plywood then durock would be to much. Plywood and durock would have worked, but why get lumber involved at that point.

 

Get a mold test done.

Also a moisture test.

 

A lot of yards store cement board outside. I've picked it up and water will remain between sheets for a very long time.

I sure would not want that in my home.

Good luck.

 

Cover a spot with 6mil plastic and tape the edges down tight. After 24 hours see if there is any significant "dew". You might also pop a tile and check under it.

If the water was sewage water then I think you could make a case for removal easily.

 

No way I would even think about leaving it. Think about how many pockets there are in that assembly to catch water.... Naaasty.

 

At the very least you should place commercial dehumidifyers , sooner the better . Insurance should pay for them if you have flood insurance . Good luck I know what your going through .

 

had 3 of them running for a week. I can still see some moister seeping out from the durock along the edge where the oak floor was.

 

I guess I should have said that i am definitely removing it. No way I can leave it there and feel good about it. Im thinking maybe Ill just start taking up tiles and pieces of durock. Its been a couple weeks now, if there's still water under there we can snap some pics and argue it had to come up. It was river water mixed with whatever else was in it. im sure there was fuel from roads, sewage and rotten stuff in it. Our well failed a water test and had to be disinfected after the flood.

 

Good move on removing the wet flooring.

After all is removed & dry you may want to consider treating it with a moldicide just for peace of mind.

Good Luck...:thumbsup:

 

I'd remove it for sure if it was dirty water. The debris in the pockets could contain organic material and grow some nastyness. Clean water would dry out eventually and probably no harm done. It's not the cbu that's the problem, it's what's on the cbu(mold spores, etc.) that are the issue.

 

yank it all out and put in a floating floor.

In case it floods again?....:whistling:thumbup::laughing::laughing:

 

I assume your parents had flood insurance?

Did the cheap insurance company tell you the oak was fine too? - with 30" of water on it?
"...since we have to pay for it - it's fine!"

See if they will pay for a mold test to PROVE to you that, "It's fine"

 

actually, the adjuster didnt even have any of the oak on there. Said he never saw it. lol. I made a quote of actual repair costs and a 20 item list of stuff he forgot. The adjuster really wants his papers signed, he got mad when we told him no way until his estimate comes up and he adds all the stuff he forgot.

 

Isn't the oak next to the tile? I thought the whole purpose of the cement board was to boost the tile up to the oak height. How'd he miss that?

 

Our friends basement flooded out not to long ago. It destroyed the tile and carpet. All the drywall had to be removed and the suspended ceiling was damaged also. The insurance adjuster went through everything and estimated $6k

The quote they got to just repair the drywall was $9k let loan the carpets, tile, doors, baseboards, casings, stairs ect ect.

They wouldn't budge at all. Said that because the stuff was in their for longer than 6y ears it was basically worthless and that's why their offer was so low. :blink:

Insurance companies are a joke. They had no problem paying serve pro $600+ a day for dehumidifiers and fans they put in the house. They were in their for weeks too.

 

Insurance companies are a joke.

I can't figure out if they are a joke, or have 5 good ones and the rest are little more than organized gambling, running numbers, a criminal racket.

My experiences are #2.

 

Uggh. Lets rip every shower out then. They stay wet all the time.

It disgusts me to read the level of abject ignorance proudly displayed by so called professionals here sometimes. Durock is concrete for godsake. It has a pH around 13. Unless the tile was put down with friggen' mastic (not likely), there's nothing in the sandwich to allow mold growth. Any of you geniuses ever get in a pool? They stay wet too. Are they "nasty"? The durock can't dry out? How the hell did the thinset dry out??

My sainted father was right. This industry is chock full of retards.

 

Sorry to tell you but you're wrong in this case.
Concrete has a ph of 12+/- when NEW. Then it reduces by a chemical process to about 8.5 (Armstrong website). Mold can grow on any surface if it has moisture and food regardless of ph.

The organic matter that will promote mold growth, in this case, is the water itself. River water contains all kinds of organic matter in the process of decay. That's the food source.

The mold will develop in 48 hours unless it can be cleaned and dried. The sandwich layer will have voids that trap moisture. And the tile layer will prevent the moisture from rapidly drying.

Pools are chlorinated. When they stop chlorinating the water would you swim in it?

 

The mold will develop in 48 hours unless it can be cleaned and dried.

This is abject stupidity on stilts. A shower enclosure with a glass door is exposed to every bit as much organic matter as a tile floor that gets flooded, and if there is a shower pan under that, it never dries out. What do people get out of persisting in this kind of idiocy?

BTW: Tile isn't a an aqueduct for whatever happens to be in the water moving over it. Most everything in the water stays on top of the tile. Grout is a pretty effective filter in that regard. Think about it for a minute.

 

Check that shower pan again. Bet that water is yummy.

 

BTW: as long as you tape the seams in Durock and thinset in between each layer, there's no reason to not stack it up other than the enormous cost versus just making deck mud and doing it the old fashioned way.

Knock yourself out. Who does your flatwork again?

 

Showers are moving water that gets replenished with chlorinated water. Shower pans are made to perc water to the drain. There's no comparison.

Flooded basements are stagnant water that may sit for weeks.

 

Not really interested in getting in this pissing match but my water isnt chlorinated....

 

While grout may filter larger material, microbial matter is microscopic.

 

If grout is such a good filter, then the water sitting in the shower pan would be safe to drink by your standard

 

Neither is mine. The point is retarded anyway. This an example of someone desperately seeking to win an argument with a stranger instead of learning to think.

 

Well show me some science to defend your point. The EPA and a bunch of states that flood(ie Mississippi, Louisiana....) would like to know that you don't need to clean up after a flood because no mold would grow on concrete because of its ph level.

You are contradicting your self! Is it ok for it to be wet or not?

Lets put this in simple terms. Every single shower I have ever taken out that water made its way between the layers had mold.

The same exact thing can happen with his flooded floor. Difference is there was much more water able to find its way under the tile. Clean chlorinated water may have been a whole different Matter but river water is a whole different deal. That floor won't dry out for months and it only takes a few days for mold to start.

Only a hack would leave that floor in.

 

I'm a little surprised that ccoffer thinks that the water that permeated that floor is harmless. Why would you take a chance (concerning a client's health) and leave the floor in place?

 

Shower pans are made to perc water to the drain. There's no comparison.

Only in your imagination is there "no comparison". About one shower in fifty is built with a pre-slope. The rest stay wet forever. Are they all a bunch of septic tanks? Hardly.

I used to have a hard on for theory. Now I'm more realistic. To encourage someone to destroy their tile floor because it got wet once is worse than stupidas****. Is a leveraging of your credibility to ill ends. It's malevolent. It's destructive.

:clap: Dontcha just love it? To this very day, units are being built with no preslope with liners. I'd not say they were septic tanks as it depends upon their use. Ones that got a lot of use had that almost eye watering industrial vinyl smell that is acidic. And so bad that a lot of times the ink on the liner is transferred to the mud pan above it. All the pan made your eyes water, but the only place I've found obama like mold/parasites is in the nearby carbon based materials...the walls.
So I think w/o any paper/wood/carbon, there'd be no mold, depend upon use though.

I do have mold on the outside of the poured foundation of my house in one spot though as water collects at that corner. There's no carbon there as it's just concrete, so I'd guess there's the media, the water and the carbon/organic material that's blown there with the wind. Don't know how this relates to this conversations, but it's interesting none the less.

It depends upon what the OP is comfortable with. He's asking the question and we are giving our answers.

This is getting sick. Permeated? Holy crap on a stick. Is tile installed outside healthy? Unhealthy? Where do you retards come from?

News flash! Tile is waterproof. Not clean waterproof. It's waterproof. The distinguishing feature about a ceramic tile floor is that it will last the life of the structure. You **** who claim to be tile men while not understanding that are a menace to the buying public. Bucket and trowel guys. uggh

 

Well show me some science to defend your point.

I already have. You're too proud of being a semi-skilled laborer to allow truth to break your helmet. Stay strong, Mookie!

Truck stop bathroom.

Think, Mookie. Think! There's tile in there. Burger King kitchen. You want to talk organic matter? How far into the deep water would you like to go? I can swim where you can't.

This isn't difficult to understand if you can just give yourself permission to understand it.

Pride is an anchor.

Sorry but it's only your opinion. Go check out cdc, epa or mold remediation. Your wishful thinking isn't science.
