Hello dear experts,
we are just at the beginning of the construction and already the first mishap has happened. The foundation slab was poured too big! Yes, it's actually unbelievable how something like that can happen, but it did (by the way, the foundation slab was made by a very well-known company).
The foundation slab is 16 cm too long on one side, and additionally, a recess for the bay window is also affected.
This was noticed during the foundation slab inspection. We were then told that it can happen (the construction manager was visibly embarrassed) and that they would fix it. Yesterday, the foundation slab was "shortened" by the said 16 cm. The slab was milled out with a kind of cutting disc, like in road construction. Since the slab is much thicker than the cutting disc can cut in depth, the rest was painstakingly removed with a pneumatic hammer. The remaining part was then replastered.
Well, now everything is supposed to be okay again, which I also really hope. - I am not an expert, so I would like to hear the opinion of the professionals here.
In my eyes, it cannot be as good as if it had been properly poured. A component was reopened and filled again. The frost skirt, which was previously 50 cm, is now only 34 cm (allegedly a maximum of 20 cm is needed and it was always 50 cm because the excavator’s bucket always creates 50 cm wide trenches).
I am already sad that the construction starts like this and I really hope that we will not have any problems because of this later on.
Which expert can tell me something about this topic? Thanks!
P.S. By the way, it is a KFW40+ house or foundation slab of the same standard.
