tolerance for 20mm 800 by 800 lime stone

[The D]

when I say wedged Deano I mean 20mm thick one side 18mm thick on the opposite edge like slate can be at times

yes m8 some are wedged

 

[Pebbs]

Deano if its the overall size the tolerance is +/-3mm, but at that kind of money you would have thought they would have re-calibrated them before leaving the fabricator. Sounds like they didn't even bother to do a QC check.

My advice to your client would be back em straight back to the supplier, but I have a feeling somewhere in their small print there will be a section on tolerance allowances.

i'd say up to + -2mm not more

so 16mm to 22mm is within + - 3mm ? just need to be clear on it for tomorrow ; )

I'd send them back for that price.

I'd send them back for half that price.

 

[nybor62]

i would,nt accept them , send them back imo

Thats gonna be a nightmare to fix, especially with the depth differences, and at £45000, i'd want them delivered by Kate Moss.
Don't even think about fixing them until the rep and the customer have a talk/punchup.

 

[The D]

The rep has had a look and given the standard response (it is natural stone you will get thickness variation and you have to allow a bit for damaged tiles they have come a long way). There was 45% damaged tiles in one crate 35% in another and 20% in the remaining five. The 6mm discrepancy was more or less shrugged of as unimportant. So my tools are in the van

 

[Ian]

What?????? No offer of replacing the damaged tiles? Unreal.

 

[DHTiling]

Not good enough of Lapicida IMHO , not good enough at all.

PHG would not dream of treating anyone like that.

Deanotile,
To the best of my knowledge natural stone is exempt from the international standard SS-EN 14411 which manufacturers of tiles should meet in terms of tolerances. So for stone suppliers the tolerances are whatever they say they are, and the specifier, client and fixer must either agree that they can work with those tolerances or, if not, chose another supplier.

You say that the rep has stated a 4mm tolerance exists. He needs to clarify what is meant by that i.e. +/-2mm (= a 4mm tolerance) or +/-4mm (= an 8mm tolerance). You have measured the tiles and have a range of 6mm, so they cannot be achieving +/-2mm, so they have either failed to achieve their stated tolerance (could be grounds to reject the shipment and find another supplier), or the real tolerance is +/-4mm which can mean an 8mm variation between tiles, which is ridiculously large and unworkable (in my opinion, I wouldn't waste my time to try and lay tiles with an 8mm variation in thickness).

If you are the fixer then you need to decide what you can realistically work with. If the client has paid £45k for the stone then it is either outrageously expensive, or he has a very large area to be tiled. If you proceed with it and the client is not satisfied with flatness and lippage then what? Will he expect you to rip it all up and do it again, at your expense? Can you afford to buy £45k's worth of stone....

 

[The D]

The MD at Lapicida has told my client that all the problems are due to the fact I am inexperienced with using stone and I am nerves about laying 800 by 800 stone (Tilers do not understand stone). The man must have a silver tongue as it looks like the stone is staying and I am not. They will send there tilers to lay the floor so I think that is that.

 

[Alan M]

its a pain loosing work but at least that job cant come back to bite you when they arent happy with all the lips etc.
i fail to see how being inexperienced etc would lessen the problems of the different thicknesses and all those chips.

 

[DHTiling]

Is this stone reclaimed...? and as for the comment from lapicida... condescending idiots...rrr:

I just looked up Lapicida's website. Their heritage, LOL, is:

"The Lapicida story began on 15 September 1984. Jason David Cherrington brought back his first samples of stone floor tiles from a Far East business trip with his father, Mr David Cherrington Senior, a successful roofing merchant. During a time when lino and carpet were the preferred choice for many homes, Jason saw the possibility of a new category – natural stone flooring.
At just 18, Jason was short on experience, but abundant confidence, vision and a healthy entrepreneurial spirit stood him in good stead.
If you have met Jason, you will know that natural stone is his life. He leads the business from the front. Treats his clients and suppliers correctly. Ensures consistently high quality products. This is how the Lapicida tradition started."

Sounds to me like a complete chancer buying cheap rubbish from China and selling it on for an outrageous mark-up to gullible punters. You're best off out of it Dinotile!
