Hello,
I hope this is the right subforum. A brief overview of the situation: My plot is on average 23 cm (9 inches) above the groundwater level. However, the surrounding ground rises, so the plot is basically a small hollow.
After the official survey, the construction company decided on a small embankment to create slightly higher elevation compared to the road (which is unpaved).
Just before the final specifications, I visited the site again—of course, it was snowy—but this clearly showed me how much the plot forms a dip. Now I would like a higher embankment.
However, the surveyor has already been there, and the building permit / planning permission has also been applied for but is not yet approved.
Is there a way to get a higher embankment without significant additional costs (the surveyor already cost me around 2000 euros)?
And if not, is 20 cm (8 inches) above groundwater level a cause for concern?
Thanks in advance for any replies.
Best regards,
MagNoona
Edit: I am building without a basement.

Sorry, I didn’t express myself clearly. I want to fill the dip on the property with the topsoil from the excavation. Of course, it is not located under the house, but in the front garden.
I also made another mistake: the figures on the site plan were not in centimeters regarding the groundwater level, but in meters, and they indicate the elevation above sea level, sorry.
So all the fuss was unnecessary.
Well, not entirely, because some filling will still be necessary since the slab should be above street level to allow proper rainwater drainage. The property is a woodland site (pine forest with sandy soil, groundwater several meters deep) which has become very uneven due to clearing.
Once again, thank you very much for your replies, it was very kind of you.

if it’s not 25 centimeters but 25 meters above "normal zero", then try reading some elevation points from your costly site plan that the surveyor marked! Then calculate the difference to the 25 m. That way, you should know how deep your groundwater is, provided the 25 m is correct!
