Retro fit wet UFH.

[charliegolf]

I posted this in the Building thread...

I am arguing with a conservatory supplier (one with a good name generally) because the floor has dropped some 5-7mm where it abutts the house, causing bad tile cracking. Obviously I want it to be their fault, cos there's a 10 year warranty on the workmanship. They say (on a perfunctory viewing) it's settlement so isn't covered. If I have to deal with it, the tiles will all have to rise mucking up the electric ufh, as well as the mess etc.

So, builders, is settlement likely after 2- 2.5 years; or is poor workmanship more likely. Who can prove it one way or the other. Thanks.

If I am left with the problem, what is the possibility of retro fitting wet UFH in the floor? Can it be used with a combi system; and are there thin, low profile systems around which might restrict how much the floor level rises (ideally an inch including tiles)? If yes, is any part of it DIY country?

Thanks for reading.

Something like Polypipe Overlay would probably be your best bet if you don't want to dig up the floor.

They do a couple of different types, Overlay and Overlay Lite.

You can tile direct to the Overlay, but if you have to take the tiles up for any reason you will damage the panels, or you can lay a 10mm ply on top and then tile, depends on what height you have to play with.

Or alternatively use engineered wood instead of tiles.
