    Default water ufh under wetroom screed

    Hello
    First time caller here. Great forum guys!

    I'm going to screed over a central heating piped ufh system (this is a beam and block concrete floor).
    I created my own falling screed many years ago over an electric ufh system; fully tanked and still dry and crack free :-) but wondered what's the best practice these days now lots of products exist.

    I've seen many formers for shower floors but they all seem to be for electric ufh systems.

    Any advice would be great.

    Hi m8 welcome

    If your working over Bison beams and will screed as usual then the Tilux shower tray former is your easiest and most cost effective option.

    Tilux wet room shower tray


    Your ufh should loop around your shower former not go over or under it. For the wet area concerned there is no great value to having it heated, the base itself is an insulator and the heat will creap from the surrounding area.

    If you were using electric I would say the same, don't go over the wet room former as if there is a drain or level problem you will loose the heating for the whole floor.

    Over the new screed you should be looking at using Dura-ci uncoupling membrane to save tile damage.

    Shout if you need more

    We have piped underfloor heating and have had problems with screed and tiles cracking. I wish we had been advised to use a de-coupling matting by the tiler, builder or plumber. From our experience we cannot believe that it isnt standard practice.

    Thank you for that extremely valid point on your experience !!!

    People can think we are trying to over sell on Durabase-ci / dura-ci for new floors when in fact it is a must to prevent tile damage on wood, new screeds, under tile heating and in screed heating due to the way new homes are constructed.

    A pleasure, I would shout it from the roof tops if I could. We paid nearly 4000 for tiles and tiling and now have cracked screed tiles and grout.

    Thanks for that advice.

    As well as the wetroom I have a new kitchen (7x7m) which will be have piped ufh and be tiled. Would dura-ci be necessary here too?

    It is my kitchen where we have had the problem. I am also having a wet room tiled and I will make sure it has decoupling matting. Am i correct in thinking there is a special waterproof one for wet rooms?
