Stone floor with underfloor heating problems!

[faithhealer]

not used myself yet but Ive heard the genesis g mat is very good any one used it

same as Deano, using it next week, half the price at the moment which JUST swayed the customer! (and this one has a Ferrari parked in the garage and he was wingeing about the cost)

I'm using Mapei's un-coupling membrane this week..

Used Ditra for years and swore by it. Recently tried g mat and really liked it too, makes uncoupling more affordable and i find the holes easier to fill with sticky

 

[DHTiling]

No holes in Mapei's membrane..

No holes in Mapei's membrane..

Is it similar to the Homelux stuff?

Got a job to sort out for a builder on a Natural stone floor that has cracked due to screed cracking, i didn't lay this floor just been asked repair this area. So if your thinking about having under floor heating, on a new screed floor, i would advise using a uncoupling membrane. I know it puts extra cost on the job!! If you don't check out my web site and give me a ring in 6 months and i will come and repair it!! :lol:

Hi Enduro,

Must be the season for it! Just spent 2 weeks repairing a floor, exactly the same scenario as yours, got loads of pics, will post them up soon, what I did was remove the tiles, ground out 5mm screed, laid in dural matting over the cracked subfloor and relaid tile over, in a "cost saving attempt" for the builder :incazzato:. Absolute nightmare of a job , started off as 9 tiles, ended up being 50 odd, and still cracks appearing in other areas. Not tiled by me originally I hasten to add. I can see it being all ripped up again in 6 months when the u/fl heating goes back on. In my opinion NEVER EVER lay stone on u/fl heated screeds without decoupler, it's a disaster waiting to happen.
