Hope I'm ok to put this on here might help someone, it's what I have left after my extension:

No links please. If you could put up an asking price and how many m2 of the mat there is, that will be ok.

I think there’s about 8m2 left; to be honest I just want the space cleared in the garage as I wasn’t very impressed with this stuff really.

I spent a long time insuring it was put down properly, I used the best BAL adhesive and good quality porcelain tiles and the stuff did attach well to the floor and give a good surface totile onto once securely down.

But what I didn’t appreciate was that any shock to the floor particularly as you can image in a kitchen with all manner of things being dropped onto it will just crack the tiles because of the additional movement that the matting allows.

I used this stuff to prevent hair line cracks in the screedbeing transferred to the tiles as I had wet UFH installed. I now have varioustiles with cracks through them so I think I’d have probably been better off notusing it at all as I did in my conservatory with the same screed, UFH, tiles& adhesive but no cracked tiles and this is still a heavily used area asthe kids us it as a play room.

So £20 to get it out of the way but I wouldn’t use it on myhouse and if you do an installation in a kitchen and the tiles start crackinghow’s that going to affect your reputation?

This is one of the best products of its type available, I'm surprised you've had issues. Did you ensure to fill all the cups in the matting before fixing the tiles? Also did you fix the tiles using a solid bed trowel and backskim the porcelain tiles?

doubt very much the product is to blame.

As above, ditra needs tiled on properly for strength.

As above for me too.... I've used 1000's of metre's of it with only 1 problem and that was many years ago.

I don't understand this ? If you drop a heavy item on to any tile, whether it has Ditra or not it could damage the tile.

I did indeed, I've done my share of tiling, what I am saying is that this product is unsuitable for the type of floor that is subject to point loading such as a kitchen, I've never had issues before and would look for an alternative if the situation arises again.

If you read the spec on Ditra you will see it is more than capable of handling kitchen traffic. I've used it in many a car showroom and is designed to take excessive weights. The main purpose of Ditra is allow for lateral movement and not vertical movement. Excessive deflection/movement in the floor or incorrect fixing methods are more likely for the problems described.

£20 for 8linear metres of Ditra flooring - that's a good deal.
I'd agree with the other comments in as much as it's possibly the best uncoupling membrane on the market and extremely surprised with the problems you are experiencing.

If I were passing your way I would have it off you.

Utter tosh and really really disagree.. Schluter ditra is used in car showrooms and even airports and shopping malls... if you have cracked tiles then that is deffo fixer error..

Simples..

Some info..:

d) Load distribution (load impact)
The bottom of the square cavities in Schlüter-DITRA, which are filled with thin-bed adhesive, directly transfer the load impact on the tile covering to the substrate. As a consequence, tile coverings installed on top of Schlüter-DITRA are highly load resistant. If high traffic loads are expected (e.g. in industrial locations), the tiles selected for the installation must be of the corresponding thickness and pressure stability. The requirements of the mandatory guideline "Ceramic Floor Coverings With High Impact Resistance," published by the German Construction Industry Association (ZDB) must be followed. In areas with high impact loads, the tiles must be fully embedded in the thin-bed adhesive. The contact surface of Schlüter-DITRA amounts to approximately 50% of the total surface. This can reduce the load bearing capacity in case of point loads. For high point loads, select a tile thickness that is capable of distributing the loads. Ceramic tile coverings should not be exposed to the direct impact of hard objects. The tile dimensions should be at least 50 mm x 50 mm.

If you are getting cracked tiles, then you have used an unsuitable tile thickness for your usage needs.

There is no point loading in a car show room all the all the cars sit on nice wide tyres spreading the weight uniformly throughout the floor.

What has been dropped on your tiles to crack them?

Bet he used those thin porcelain tiles you can get from the sheds.

Sorry to hear you're having problems, but EVERYONE is talking from obvious experience with ditra matting, we've fixed 1000's of meters of it it all possible locations, because we know we have no worries if we've used it.

Hi, Do you still have the ditra for sale? Seems like everyone is too busy giving you 'advice' rather than offers to buy the stuff! Regards, Olly

It made me LOL to read that he hates the product, thinks it's useless, would never have it in his house again, but instead of setting fire to it, he's trying to sell it for a pony. You can tell he comes from the Black Country

Ha! And Im trying to buy it!!! You can tell im a tight northerner!!!

You're a southerner to me

Dropping things is not point loading it is impact loading. This is affected by the kinetic energy built up during the objects falling. This can increase the force on impact by a very considerable amount. Point loads are static not dynamic. Ditra is great for point loads. As per previous

Bah , wish I had bought this now !
