Poor Tiling Job? Advise please...

7.1.9.1
Finished tile surfaces
The surface should be true such that, when checked with a 2 m
straightedge with 3 mm thick feet at each end, the straightedge
should not be obstructed by the tiles and no gap should be greater
than 6 mm.
There are permissible manufacturing tolerances for ceramic tiles
defined in BS EN 14411; certain types of tiles, e.g. extruded or large
format, might have permissible surface flatness irregularities that
cannot satisfactorily be accommodated within the surface flatness
tolerance permitted to the tile installer; this should be taken into
account when evaluating the achievable flatness of a wall floor tiling
installation.
NOTE Where adhesives are used, this degree of accuracy can be
achieved only when the background surface is equally true.

7.1.9.2
Across joints
There should be no appreciable difference in level across joints
(commonly called “lipping”) and the maximum deviation between
tile surfaces either side of a joint, including movement joints, should
be as follows.
a) Joints less than 6 mm wide, 1 mm.
b) Joints 6 mm or more wide, 2 mm.

Is someone able to point me in direction where this is stated online?

trying to find evidence to confirm this however cant find online as have to buy book for standards at £180!

Cant put this into a report without knowing for sure what im writting is true?

thanks

Sorry you won't find it online (unless you google "BS5385" and find it through file sharing - not that I am suggesting you do of course!)

My copy is legit, but copyright and watermarks forbid sharing.

The quote is correct but be aware that BS5385 is industry guidance - not law.
It's something to work to but in reality, if any of us here were making 1mm lips across joints less than 6mm - we would not be working to a good standard.
0.2mm is poor, never mind 1mm!

Agree!

The builders have said :

'With regards to the leveling of the tiles. BS 5385-3 states that a 2m straightedge should be used when trying to measure the level of the tiles. Any gap over 3mm is classed as unacceptable'

is what they state true or can i argue the point or am i having to accept this work they have done

Irrespective of the above, you have received poor, sub-standard workmanship!

Looks like your builders' copy of BS5385 is somewhat out of date!

That's basically saying that the floor may not be totally flat, but there should still be no lippage. In other words, you're following the contours of the floor.

It's applicable to walls and floors.

There's heaps of BS guidance on substrate prep too. Particularly with prep of substrates for mosaics.

i would use the 1st port of call by taking photos of the job before it is removed as evidence as it simply looks like a pile of poo!! if it looks like that its wrong imo

the cuts are awful the mosaics are squint the grouting is poor never mind this straight edge and all is well the jobs awful

Ah yeah, I know.. Forgot which thread I was in lol!?! Thought it was the dodgy floor!?! 😉
