Hello everyone,

I'm redecorating my bathroom and after removing the tiles and bath have discovered what seems to be a rising damp problem. The tiles fell off without much effort, which I believe is due to the damp rising up the wall and affecting the adhesive.

I've attached a picture to this thread. This was taken about 2 weeks after everything was removed and the room left to air. Both of the walls featured are internal - the one on the left to the internal hall way and the one at the top of the picture to the enclosed communal hallway.

It's a ground floor flat.

Is the problem coming from the foundations?

Any help on what the cause could be, and any possible solutions would be much appreciated.

Thank you

Rising damp is a myth, though it certainly looks as though your wall floor joint is being affected by external water. Could do with a few more pics of the other side of those walls
 
Given that the walls are internal its possible that the cause is rising damp - have you carefully examined the other sides of the walls in question for signs of damp - probe any skirtings?
Is the whole ground floor of the house a solid floor?

You have gypsum plaster and it will all have to be hacked off and replaced with a 3:1 sand & lime mix. Remove the wood fixings.
When you are back to bare bricks then post photos please.
 
Since that photo was taken the damp patches have reduced more. Photo attached. It took about another 2 weeks to get this stage, so about a month in total since the bath and tiles were removed.

Seems like it's not a major damp problem until the ventilation is removed.

Its irrelevant - I've suggested above what you should do.
