Hello everyone,

our masonry is damp and we are afraid of mold spores!

BACKGROUND:
Our shell construction made of brick masonry has repeatedly been exposed to rainwater since early February 2016. The first major moisture occurred in the hobby room (basement). The water was 2-3 cm high. We removed the water ourselves - despite the turnkey construction. When the shell construction was finished, we again had 3-4 cm of water in our 10m² pantry. Removed again on our own. Above our pantry is the roof terrace, which is the cause of the water entering during the shell construction. Our windows have been installed for 3 weeks. The waterproofing was only applied today. Over the weekend it rained heavily again and water accumulated in many areas of the house (ground floor + upper floor + basement) and the masonry became damp.

The window installation (fault of the builder) and the sampling (fault of the builders and ourselves) took longer than expected, so the move-in date has already been postponed by our builder from the end of October 2016 to the end of November 2016. I can well imagine that the builder will need to plaster the interior walls and lay the screed soon in order to meet the scheduled move-in date.

Now we are worried that the moisture in the masonry will remain and cause moisture damage or later cracks. It is clear that plaster and screed also generate moisture. However, in my opinion, the already soaked bricks should be sufficiently dried before further work is carried out. Our builder apparently sees this more relaxed.

Would you insist on technical drying now or is our situation quite normal and not serious?

Many thanks in advance!

Best regards Manuel

I would like to point out that plastering should not be done when the masonry is still too wet, because then the plaster will not hold. Moreover, plaster is not waterproof to water vapor, so moisture can still diffuse after the interior plaster has been applied.

In my first house, water also stood for weeks back then, and it caused no damage whatsoever.

Best regards
