Strong floor tiles for half wooden half concrete kitchen floor with underfloor heating
Anonymous user 23/02/2024 - 2.55 PM
Hi We've had our kitchen extended and so half the floor is floorboards and the other half concrete. We had under floor heating put in and then laid a limestone tile floor. Where the different types of floor have warmed and cooled down, presumably at different rates the tiles have cracked. Can anyone suggest the best option to replace them with? Thanks in advance. Thanks for reply house doctors 😊. They did ply it first though and put some kind of mat stuff across the whole floor.
Are you a tradesperson and able to answer this question?

sounds like warmup matting underfloor heating which should have latex self levelling compound spead over it before tiling. Also two different types of adhesive should have been used for concrete and timber floors. If the same adhesive for concrete floors was used on the timber floor it could fail and lead to tiles becoming loose and cracking.

I would imagine that over the timber part of your floor they have not overplayed 18mm WPB ply (on top of the the floorboards) you can not tile onto floorboards.
You do not need strong tiles you need a good tiler

There is one reason only the tiling has failed no decoupling membrane and no expansion joint was put into the tiling
Where timber meets screed you must put in expansion joint the 2 different substrate will move at different rates and using heated substrate will make the problem even worse
