Narnulf136810 Feb 2023 20:10Hello everyone,
We are currently planning our house, and according to the soil report, it looks like we will need a well foundation. Initial research shows this could add at least €10,000 (around $11,000) in additional costs.
Has anyone had experience with this? Especially the pricing would be interesting.
We plan for a 120 m² (1,290 sq ft) footprint plus 60 m² (645 sq ft). For the garage, we have a quote of €15,000 (about $16,500) for the related concrete slab and another €15,000 for the garage itself (excluding the door).
According to the report, a slab foundation would be possible if we include a basement. Now I’m considering possibly building a basement to avoid the well foundation.
The idea is, instead of paying €30,000 (around $33,000) for the garage plus at least €10,000 for the well foundation, to invest the money in a basement. I have requested a quote for that and expect it early next week. But I wanted to ask here beforehand if this is a completely dumb idea.
Good luck and thanks in advance!

xMisterDx11 Feb 2023 15:07Why do you have to use well rings for the foundation? Possibly high groundwater? Hydrostatic pressure? I would be surprised if you get that done for 10,000 EUR.
We had to do a similar approach, strip foundations at a depth of 3.5 m (11.5 ft). It cost an extra 27,000 EUR. Stronger slab, better reinforcement steel, and so on. Well rings or piles would have been even more expensive...

I also think €10,000 is quite optimistic. I recall a thread here about pile foundations where the additional costs were over €30,000. At least, that’s how I remember it. This extra expense definitely needs to be included in the purchase price negotiation for the plot of land!

This extra effort definitely needs to be factored into the purchase price negotiations for the land! Go ahead. If he doesn’t buy, usually there are around 10 people lined up ready to compete for it.

We had to do a similar solution: strip footings at 3.5 m (11.5 ft) depth. It cost an additional 27,000 EUR. Stronger slab, better rebar, etc.
Well rings or piles would have been even more expensive... It’s recommended in the geotechnical report, but I don’t really know much about it. I’ve added some information from the geotechnical report as an update to my first post.
At least 10,000 EUR was the only number I quickly found. I also expect it to be more and am therefore considering whether we should build a basement instead.
Instead of spending 30,000 EUR (for a 60 m² (645 ft²) garage) plus 10,000–30,000 EUR for the well ring foundation, the idea would be to spend 40,000 to 60,000 EUR on a basement and get more value out of it.

This additional cost definitely needs to be factored into the purchase price negotiations for the land! As I said, 10,000 EUR was the only number I’ve found so far.

It probably depends on the region—in Saxony-Anhalt right now, likely not.
Have you ordered a complete house or are all services contracted separately? We have a provider for the house, but the slab foundation is not included.
