Tiling on caber flooring on a new build

[Ian]

Chipboard is probably the worst thing to tile to, except maybe sand, but seriously just get some backer boards, the job will last and be of a good quality and you won't have to go back and fix it when the tiles come loose, which they will if you tile on chipboard.

It is not just to do with deflection for the use of ply.. 15mm offers the best resistance to water ingression and BS5235 does state that is minimum to be used.

You can however *** said above use a backerboard like Hardibacker250.. these are water resistant and do not swell or leach resins like ply can..

even if the floor is 15mm chipboard with not much bounce at all

yes even with the chipboard @ that thickness. layed staggered 2mm expansion gap between boards and primed back and sides

so how do you get over the height rise outside that room where there is a carpet. Wouldnt it look funny?

 

[Ian]

You can get threshold strips to connect the 2. If you use a 6mm backer board you will find that the difference between the backer + tile and carpet + underlay, isn't that different.

Is there any TRV's on the pipes..?

 

[brickyman]

trv's?

Radiator valves..🙂

nothing in there at the minute. Just the pipe work (water and soil pipe) sanitary ware getting fitted after tiling. I think this makes for a better job?
