Yes David, I am sure I would have tiled it. Not questioning your judgement or what you are planning to do.
What I am trying to see, is what guidelines are out there from TTA, uncoupling membrane manufacturers, BS, or any other body gives for when you turn up at a job to find cracks in a sand and cement screed, wether 1mm or 5mm.
It sounds like, from your replies and none replies form other notable trusted advisers that it is completely down to the tiler to make the call irrespective of there experience, wether that be 6 months or 40 years on the job.
I would in my "experience" tile most of these jobs, but the reason I ask is because I would like to know if the manufacturers, BS or TTA or the law are on our side if we tile these job in go faith using our judgment and they fail due to a bad screen. I have seen many screeds with wet ufh not crack. So is the presence of cracks proof of a incorrectly laid floor?
I did a floor the beginning of last year. Original floor was travertine, 50m2 on wet ufh with expansion joints in all the correct places, but full of hairline cracks.
I had to lift and replace with porcelain.
On lifting this floor I found no uncoupling membrane, possibly the only mistake that was made?
But as I lifted the floor I found that the screed was laid so badly, by this I mean a layer of screed was laid over the ufh pipes and trodden down and left to partly dry, lunch break or overnight, foot prints were as plan as day, with the top layer not bonded to this at all.
So this person doing the tiling would have looked at this job and thought, looks good, expansion joints, hairline cracks, good to tile. Yes no uncoupling membrane, but seeing the state of the floor and the debonding in the screed, how would he have faired with the uncoupling membrane supplier if one was used and failed? If he was a TTA member? Drummed out the club or backed in a court?
David just trying to have a debate and get the feelings of other members.
Having been away from the forum for a while, I have noticed that some of the notable members who, in the past would have jumped in with an opinion are not so vocal now they have been made advisers now 😉
Sorry if I have hijacked your thread.
