Important Changes to Tiling Standards

[Ajax123]

are you talking screed or concrete.

Surely levelling the floor is a contractual issue.

As you rightly say flat and level are different things. I would think flat is more important than level if there is only 25mm fall over 6m.

The screed standards and the concrete standards are generally not very explicit about specific requirements for flatness or levelness. But the contractor will presumably have a specification for the concrete and you will have a specification for the tiling requirements which should be explicit.

Yes these are supposed powerfloated screeds., for bovis, Redrow.. laid at slab before walls erected.
it’s a common issue where we are., the nhbc spec is very vague regarding tiling.. (as always).
Trouble is they’re getting ground workers to lay Screeds!

If I were you and you didn’t want to ditch the job then I’d just charge for my pain. I’m well experienced at dealing with pathetic floors (@John Benton) I’ll do what I have to so long as it makes financial sense. Sooner or later the QS will realise that it’s cheaper to employ professional Screeder’s to do the job properly than to pay you to sort out bad screeds.

Hi gents..
So after a day of emails and phone calls for future reference.
I have it from the horses mouth that is our local nhbc inspector..
screeds are allowed a tolerance of 25mm over 6m, or 4mm per m.
As w knew, and the tolerance for tiling is -/+ 3mm over a 2m srraight edge.
Straight edge being the key word. Not level.
So if the kitchen for example is laid to flat, and then the hallway or any adjoing Room needs tiling as an afterthought., any undulations in that are are treated as a separate entity, and need grinding down/levelling to suit..
thanks for all the reply’s., so kind as someone else is covering the costs then all good.!!
Cheers lee

I posted yesterday about the poor job that has been made of our shower wall tiles. Since then I’ve become something of an expert on tiling (haha) and have another query regarding our floor tiles. The lippage seems excessive in areas. Photos of the worst area below. Is that acceptable?

Further more this week I’ve found a cracked floor tile that definitely wasn’t there before. No one remembers dropping anything on the floor but it kind of looks like a blunt force from above so I am willing to accept it must be something we’ve done. However, given the poor job elsewhere there’s a slight concern this is due to the way the tiles have been laid?

Bathroom all 7 months old. Will include a picture of when the tiles were being laid.

Thanks!

I'm afraid it's atrocious. Both in method and finish

Could you elaborate so I can question them when they come round tomorrow?

It's been spot fixed and fixed to ply. Should have been overboarded with cement board, levelled then tiled use a notched trowel.
Was it a general builder by chance?

By spot fixed do you mean dot and dab? As

Thankyou. I don’t think it’s been spot fixed, I remember them laying it and the whole floor was covered in stuff I think? That last picture is before they cut the tile for round the radiator pipes.

Could the fact it’s been fixed to ply have caused the crack?

Does that lippage look like it conforms to industry standards? Does any of it conform to industry standards?!

Surely the best way to get new houses tiled correctly using to correct preparation materials is for the likes of NHBC not to sign houses off If they have tiles on ply walls . Heavy tiles on skimmed walls etc . Surely the the tta should canvas them explaining risks associated with bad instalation .Or is it NHBC don't care because they don't pay out either

 

[One Day]

Tta should be much more proactive in many many areas I think. But there's always that little problem of funding and turning a profit

And you need to remember that most builders cannot read, so the cost of producing picture books that can explain best practise tiling techniques would be very high indeed!

They would soon learn to read if guarantee man wasn't signing it off and mortgage man then wouldn't release the money to client who needs it to make stage payment .

 

[Perfect Tiling]

I've had a few floors and walls to retile after a couple of years.....customer usually tries NHBC and the usual answer is the tiles are cosmetic and not structural so not covered
