ᐅ Water inside a fully enclosed shell structure

Created on: 7 Jan 2022 06:49

Hello everyone,

We are currently in the construction phase of our single-family house. Current status: shell structure complete, roof installed, windows fitted, and sanitary rough-in finished.

Due to increased rainfall lately, I have noticed water appearing on the walls only on the ground floor and first floor, on the side where the bay window is installed, causing visible water puddles as shown in the photos.
I am unsure if this is normal.

Our general contractor will only be available again next week, but I would like to gather some information in advance and hear your opinions on this.

Thanks in advance and Happy New Year.

Best regards

If you don’t have a building expert to accompany you, I would bring one in now, as everything is still undecided.

What should you do once the water is inside? Wipe it up? Leave it as is?

The small amount will dry on its own. However, you can also speed up the process if you like. With the screed, much more will come into the house.

Below the windows, everything is still open, with no sealing or insulation. I would consider this normal for now, but it should still be monitored closely.

However, the screed is usually installed as a floating screed, meaning on separation layers, nowadays on insulation. If there is moisture underneath, it gets trapped. Therefore, it needs to dry out beforehand, but this is also normal.

That goes without saying. I didn't think it needed to be specified.
