Hello! We have a house from 1928, and we have finally gotten to renovating the ground floor. Here, there are masonry walls while the rest of the house is wood.
The masonry walls are at the back about 90 cm below (drained) ground level.
The front side is free-standing.
Now we have torn down all the interior construction and found both this and that, but what I'm wondering about today is what you see in the picture.
- on the inside of some walls, there is gravel. (Otherwise, it's an uninsulated slab)
Now we want to pour concrete over this gravel, should we put plastic first or just go ahead with the concrete?
There will definitely be more questions in here now, we live in Norway and of course we want to build to our Swedish standards... since it's actually better
Regards,
Rebecka

Simply placing some form of plastic on such a narrow strip will not "help" against rising moisture to the slab. Just make sure there is a capillary-breaking layer of gravel where you are going to cast again, and reinforce between the existing slab and the wall, then there should probably not be any problem.
