ᐅ Crack in the Concrete Floor Slab

Hello everyone,

I bought a house built in 1959.
When we removed the screed from the ceiling slab between the ground floor and the first floor, a crack became visible.
It runs almost exactly along the wall below.
Is it possible to make any judgment about whether this is dangerous or not at this stage?

Best regards,
Robin

1. Only with a structural engineer.
2. If the house was built in 1959, then there probably won’t be a problem.

Choose the answer that suits you best (I’m a pragmatist and would personally go with option 2).

I wanted to avoid just closing my eyes and pushing through. Visually it doesn’t bother me since there will be a floating floor heating installed there. But since it’s already open and visible, you might consider doing something about it. Now is the only appropriate time. I’ve already asked a structural engineer, but he said it’s not within his responsibility. A building expert would have to be called in for this.

Do you have a reinforcement plan from the house documents?
Maybe the ceiling consists of two elements that meet at this crack and rest on the wall.

No, someone experienced needs to inspect it on site.

I have seen much worse. Just have a professional take a look if you think it’s necessary. To me, it looks like the usual settlement and stress cracks. I don’t think it’s anything serious.

I wouldn’t have even noticed the mini thing 😉.
