What one did you use? and does the floor sound like it's crunching?

 

[nipper76]

oh well yes sounds like you have the same issue i used the blue one made by blanke german same as gmatt and the old dura base what did you use?

I personally haven't had a problem but know others have. It seems a bad batch made around towards the end of last year is to blame.

There are a few thread already but some you won't be able to access

here's one you can

thanks for that ! dose not sound good i lifted a tile and looks like the mat has come away from the backing felt clean and now the magority of the floor looks like it is floating and starting to crack up the client is not best pleased and matt supplier is saying poor work manship or adhesive!! socan see this is going to go and go!!

There is a repair system by injecting the floor. I know Dural are sorting their problems out with failed floors, not sure on the others. But it sounds like you have the same problem so I wouldn't let Blanke palm you off

hi nipper
have been laying stone floors for 30 years never had a floor fail, all of a sudden i have had 3 floors fail this year and the only
thing different i have done is to use G matting, have never had a problem with dittra matt. any one else out there had any probs with
G matting this year

 

[nipper76]

interesting i have a feeling that these mats are out coppying ditra mat and posibly cutting a corner! as the gmat , dura base and wounder mat and the anti crack mats that are all being sold by diffrent companies are being made buy one factory and just being pacaged acordingaly!
what was that out come of your floors from genisses?

hi nipper
no outcome yet, all problems ongoing. trying to establish reasons for matting failing. going to involve the TTA. it seems a difficult thing to prove. am also trying to find out how big a problem it is with other stone or tile fixers
