Is the surface weight of the cement screed in old buildings not too high?

Hello everyone,

I am in the process of renovating my house. Old building, but solid construction. The ground floor is completely basemented. The floor on the ground floor is made of concrete. The construction (the roof of the basement) consists of several concrete beams with reinforcing steel at 50-70 cm intervals and bricks in between. According to some craftsmen in the past, this was common practice. On the floor in the living room was parquet flooring and in the kitchen mosaic. Both were removed. I now want to level the floor to the height of the hallway. 2.5-3.5 cm.

I was suggested cement screed.

I asked if it is too heavy for the floor!

The screed project manager said the floor can handle it!
The structural engineer said it should not be a problem either.

According to the offer and structural engineer, I come to 60-69 kg / m2.

Do you have experience with such constructions?
Should I be concerned about the surface weight?
Furniture will be added and there will also be several people visiting.

Regards
Thanos

You have a structural engineer who says that it will hold and now you are trying to get this confirmed in a forum of clueless homeowners?

Hi

Thanks for the feedback!
Yes and no. I also wanted to know if anyone is already familiar with this ceiling/floor construction...

I would trust the structural engineer. That’s what they are there for. Our old building has wooden beam ceilings, so it’s completely different. It wouldn’t be possible for us, but as I said - the structural engineer is a professional and will assess it correctly.

The written response from the [Statiker] is also here! So it's all good...

Hello Mr. ....,

yes, that should work. As already mentioned, with such old components you can never be completely sure, but it is very unlikely that a problem will occur. In this case, you can still install a beam.
