Hello,
our construction project is almost complete, but we have an issue with a damp band around the entire house. At first, we thought it was because the ground floor ceiling was still drying, but now the brickwork is almost a year old (and the concrete slab was poured even earlier), and the dampness is still there. Our builder also said at the beginning that this would disappear within six months, but now he claims that it is a problem with the bricks. I am no expert, but it seems more likely to me that there is an error by the mason (are any damp-proof courses or membranes installed here?).
Our house handover is coming up soon, and understandably I want to have this clarified beforehand 😉
Thank you very much in advance!

A brick veneer facade is ventilated from behind, so something like that usually has no effect. It could be that something has fallen off and the ventilation is no longer functioning. But all of this is just speculation. The only option might be to use a borescope camera to look through the gaps.

yes, the interior is completely dry – we have installed underfloor heating, but I can’t quite imagine what effect it could have in this case?!
In any case, it definitely doesn’t seem to be a typical issue...

I can only assume that it is due to the brickwork. I mean, a lot of water evaporates at the level of the concrete ceiling. Construction today is quite fast, so the ceiling, which may have been poured conventionally (?), probably wasn’t left exposed for a very long time. The water soaks into the brick and then evaporates from there into the surrounding environment.
