what would you do????

[Andy Tiler]

ok im on a job at the mo, 4 bathrooms 3mtrs max each floor ive ripped up the old tiles to reveal a gypsum floor! theyve got showers in these rooms that ive also ripped out cos theyve been leaking and rotten all the timber under the trays,they must have been leaking for 3years since they were built??
these floors are 60mm thick and wet through!!!! ive already been waiting 7 weeks for them to dry out and ive got heaters on them aswell. dont mind cos ive got plenty of work..but the hotel is now getting impatient cos they are loosing loads with the rooms being out of action.been over there today with my tramex damp tester and they are still slightly damp....so they said to me today we cant afford for the rooms to be out of action any longer!and if there not dry by monday just tile them damp or not(me i cant if there not dry enough,because if it fails its down to me)hotel we,ll sign anything you want to cover you if it fails saying its down to us. we,ll pay you to come and do it again!!!!! never thought i would be in this situation.. anyone know of a way to dry these floors any quick smart?? :mad2:
cheers..

Dehumidifiers work well, what about the possibility of using green screed on them?

 

[DHTiling]

An ordinary damp meter is no good.. ..

Here's a few piccs!!

Had a dehumidifier on it for a week! Pulled a bit out first few days.. And that's it?.

I've got a £400 tramex Dave it's not ordinary!!!! Lol

 

[bugs183]

As Trevotine says Green Screed may be an idea, Bal Tech would give you advise, maybe use Green Screed and Ditra (if you can???),then tile over, i could work!?
It's sounds a bit bodgy, but then tiling onto a damp screed isn't the best!!

Who in there right mind stuck gypsum boards down in a shower area.....

 

[DHTiling]

You need to measure moisture in anhydrite over 48 hrs.. a simple touch substrate meter does not read at the base IMO..

If cement screed gets wet it can be fine to tile when some damp is within it and use a vapour membrane but anhydrite you have the issue of sulphate migration Andy..

Have you tried a simple sweat test..?

I know it's damp though Dave,you can see it! Most of the floor is bone dry but there's a patch right near the door that's staying damp! and I can't tile until its all dry?. Grrr

Bummer... lol ..

So Andy, this is a floor laid on plasterboard? I thought you meant a gypsum screed, ie calcium sulphate, I was going to agree with Dave about the sweat test. But is this just water damaged joists? Not to sure what the problem is now.

Evening phil! It is a gypsum based floor mate!not pboard....the joists under the step and shower are goosed hence ive ripped them out.its just the floor is taking a while to dry?.... Lol

 

[White Room]

For some reason I got it wrong, thought it was boards....

 

[The Legend; Phil Hobson RIP]

Hi Andy, sorry I got the wrong end of the stick, in that case I would take Dave's advice, a sweat test.Put a 1m2 sheet of visqueen and lay it on the suspected damp patch, leave it for a few days and see if it sweats, better still a hair hygrometer test.

Andy, this is what I would do, and you can take it or leave this advice. In situations like this (and funnily enough I have a similar situation going on right now). Tomorrow morning I am issuing a 'disclaimer' because I am now seriously under pressure to bring a contract in on programme. It will basically state we will undertake the works as instructed but we accept no responsibility, in any shape or form for any failures, as a direct result of the substrate not being ready to recieve the material.

The client then signs and dates it, and you carry on.

Basically you throw the problem right back at them.

Good luck

3 years time they will be revamping it again anyway...

Thanks Lynn,so this would stand up in court? In waiting for the TTA to contact me today to see where I stand?
Cheers Andy

Stand up in court ? Doubtful but it would depend on how far the lawyers pushed the matter. The way I see it its not about what is right or wrong, its which solicitor convinces the judge or jury .

Going to an arbitration is or was different. You and the other party would say your peace to the arbitrator and he or she would give their opinion and the matter would be closed.

Its been a while since I had to do that and would be interested in what you find out Andy, all the best

Nicholl and Clark do a diconnecting sheet, could'nt find a link.

It states on a brochure I have "It is ideal as an uncoupling membrane where the condition of the floor does not facilitate good adhesion between the tile adhesive and the substrate such as old or contaminated screeds"

Is that not for temporary floors whitebeam???.
I'm thinking of going down the route of mechanicaly fixing Wedi boards to the floor? I know the damps still there but it needs doing ....

 

[White Room]

Just an idea to see if it was any good...
