Floor fail...but why? - BCT "floor" tiles that are rubbish - TilersForums.com

A few weeks ago I posted a thread on the main forum about British ceramic tiles cracking on all Hardiebacker joins.

As it stands this hasn't been sorted yet as the rep was hard to get hold of and eventually said i need to go back to supplier.

I know they are going to say its my fault and I have to put right at my expense which i will do but looking at the pictures some of the cracks you could get a sheet of paper in there.

The house is a solid 1980's build, wooden floor boards in good condition, medium upstairs bathroom, all boards screwed down with 50mm screws, solid as a rock, Hardiebacker staggard over floorboard, screwed down with 25mm Turbogolds onto Ultra rapidset, 2mm gap between boards and joins taped.

Tiles laid day after floor prep with Ultra rapidset and 10mm trowel.

Fitted in Feb and lasted 5-6 months before cracks, never had this before but need to know whats caused it.

If I was reading this I'd think movement but from what and where? everything was as solid as a rock and as tight as a drum. Are the tiles fit for purpose?

As I said about these tiles previously they are not fit for purpose on a floor.
It's trying to prove they aren't fit for floor use.
Did you tape the joins of the Hardie?
If you didn't they will probably point to this as the cause for the cracks.

All joins double taped.

Are any of the tiles loose?

 

[Bathfix Bob]

No tiles loose just pulled apart on hardie seems, all tiles back skimmed.

Some of those tiles are soft as ***** and today's modern adhesive are so strong it's the tiles that give before the adhesive..
It will come down to movement on the floor.....every wooden floor will move slightly...most tiles will take it no problem.....and imo there lies the problem.....***** tiles on a wooden floor!!

as stated stef,
tile does not break at 2 cm from the edge. as photos n° 5
I think tiles too tender, the hardest tiles are recommended.

 

[Time's Ran Out]

As previously stated - this is a thick wall tile biscuit that I would refuse to use on a floor.
Too late for Bob and with any board material any joins will travel through this soft tile.

Like the BQ porcelain tiles of a few years ago perhaps a thread solely for this tile should highlight the problem.

So how do you know what tiles to fit? they do say floor tiles on the box.
