Expansion joints with UFH

[slikt]

We are having nitemares with UFH, the builders & plumbers will not listen to me when i tell them the procedure for the UFH, as a result we are still going back & repairing a floor 2 1/2 years later, we never done initial installation. tbh the whole floor has to come up.
On another build the plumbers turned the UFH on full when commissioning & the rooms temp hit 38, they shocked the concrete that much that there are 10mm cracks throughout the house, luckily we only tiled 2 floors but i know we will be back for ongoing repairs.
Listen to the advice from Dave & save yourself a lot of hassle, you have done everything right so far.
What did you think of the profix? was it the pink/blue bags?

Yeah thats what i've been reading and I have to say the first time i laid UFH years ago, I didnt do the right prep work (rushed into it and was given the wrong adhesive by customer, but he wouldnt budge) and it was a , my fault and i've learned from it, so with this one, i've taken my time and done everything to the letter. Thank for this site. . lol and again thanks to all that have given me their help and advice 🙂

I really liked the Pro Flex, never used it before but the guy at Tile Giant done me a fantastic deal on my tiles and adhesives, I usually use BAL single part, found the Mapei gear to be as nice to trowel, very fluid yet elastic, hopefully it wont let me down with my floor. . lol

Phew, thats always a good sign. Finished the grouting today after leaving it 5 days to fully dry (naturally) another week till i'll commission the floor. .🙂
