Hi everyone,
I was at the construction site today and was a bit surprised at how deep our house is set... maybe the site is playing tricks on me, but I looked it up and most houses have the finished floor level about 30cm (12 inches) above ground level.
If the slab is really too low, that would explain why we have so much excavation. (The architect said during planning that there wouldn’t be much excavation and it could be spread on the property.)
Regards,
Marvin

Who says the top of the slab has to be 30cm (12 inches) above ground level? Basically, the slab is set at the height planned by the architect and approved by you. In other words, it is executed exactly as you agreed, or the structural builder may have made a measurement error. There is no standard height for slabs. On top of the rough floor, there will be about 20cm (8 inches) of floor build-up anyway, right?
What does the planning submission say where the cross-section or elevation is shown? That should indicate the relationship of the slab to the ground level.
Besides, there are already exterior walls on it! Where were you when the slab was poured and the insulation was installed? If the slab is really too low, then it’s already too late.

The site was surveyed before the road existed, and the reference point used was a drain cover.
The foundation slab was probably poured midweek; I was away on business all week. Yesterday, my wife visited the site with the site manager and asked if the slab wasn’t set too low. The site manager thought everything looked fine so far!
Okay, there is no standard height for foundation slabs, but are there actually people who build partially underground?

It’s hard to tell, but I would estimate that the OK slab is about 20–30cm (8–12 inches) lower than the curb edge. Then the screed will go on top, but I’m still pretty sure it will remain below ground level. Even if the slab is flush with the drain, it will probably be impossible to create a slope away from the house there, or am I misunderstanding something?
