Hi folks - need some help in diagnosing some possible damp in my kitchen floor - I'll start from the beginning :-
Our new kitchen diner was once a 3rd reception / small kitchen / downstairs toilet. There were approx 3 walls that separated them. To create our new kitchen diner we removed all of these internal walls completely. At the base of the walls we found that they sat upon some black powdered type soil ???.
Anyway - we filled these "trenches" in with mortar and then levelled things off self levelling cement. I noticed that as the cement dried out the areas where the walls once stood took longer than the rest of the floor to dry. I figured that the mortar still contained moisture so thought nothing of it.
We've now had our new kitchen installed but we seem to be having a problem along where these walls once stood. Whenever it rains these areas on the floor start to darken and then can feel damp to the touch. I've dried them out using heaters and fans but they still kept coming back. We've had a dry spell lately and they appeared to dry out completely until it rained again this week .
I'm confused here as these areas are in the middle of the room so have a I got damp ? and why is it present only where the walls once stood ? and what can I do about it ?.
Cheers.
