Discuss Expansion joint in the Canada area at TilersForums. The USA and UK Tiling Forum (Also now Aus, Canada, ROI, and more)
The problem is it will look soooooooo wrong since they are large format should i not open up a expansion on the correct side of door frame instead?You need to follow the expansion from the subfloor up thru the tile. If you don't the tile WILL crack
Very often put in wrong place by the screeders (brainless idiots) and bad site management
Yeah all done.I take it you have layed this size tile before?
Ufh commissioned?
Uncoupling membrane being used?
Not necessarily brainless...2 things spring to mind. First at least there are joints in the screed and second the advice on joints in door thresholds says that the joint should go on the larger side so if you have a joint from a corridor into a room the joint will be placed on the room side of the threshold. The issue of course with that is that the tiles may want to extend to the corridor side of the threshold depending kn the placement of the the door itself. The screeder may well have got it right.You need to follow the expansion from the subfloor up thru the tile. If you don't the tile WILL crack

The expansion on a few doors is on the wrong side of the door frame but still within the door frame. So i was hoping a 40mm overhang shouldnt really effect tile as i also have anticrack matt installed aswellWhen you say on the wrong side. Which side are they?
Anti crack mat will be no good with horizontal movement only lateral movement. Bridging over the movement joint in the screed, which can and will have horizontal movement (if the two side of the joint have floors at different temperatures, as can happen for example) will crack the tiles running over them if fixed correctly.The expansion on a few doors is on the wrong side of the door frame but still within the door frame.

Sorry but that's complete rubbish.Couldn’t agree more with Julian. It’s laziness and bad management that screed joints aren’t below the door. At this point of the build there are drawings that if looked at would avoid the problem.
Anti crack matting will help as it will diffuse the movement across the joint. If it's only 40mm out from the tiling point if view that should be fine. I've seen this done many times.The expansion on a few doors is on the wrong side of the door frame but still within the door frame.

I bow to your knowledge of the chemistry of these screeds but I’m surprised that you think my statement is complete rubbish, how can it be?Sorry but that's complete rubbish.

Sorry bad day. Was a bit rude of me.I bow to your knowledge of the chemistry of these screeds but I’m surprised that you think my statement is complete rubbish, how can it be?
In the real world how can it be argued that with a bit of thought a properly planned joint isn’t better beneath the door?
Horses for courses!
