Soil survey before purchasing property?

In the 60s, there probably wasn't a white tank yet... So I would be pretty sure that in that year of construction, building was always done above the groundwater. And if the groundwater level later shifted (for whatever reason), they will know that too.

In the 60s there probably wasn’t a white bathtub yet... I’m pretty sure that in that year of construction, buildings were always built above the groundwater.

Not a white bathtub, but to my knowledge, back then one could make so-called black bathtubs with bitumen; and that even with pressing water.

Sure, and I can tell you what these bathtubs probably all are today.... always damp somewhere.

You think so? but TE wants to build new; so we don't have to worry about that

I have built my floor slab here 80cm above the 100-year groundwater level without a basement in the existing building.

Around it, all houses (about 20) (built between 1955 and 1962) have a high basement, which stands about 30cm above normal groundwater (and clearly in the maximum groundwater).

Not a single basement there is truly 100% dry.

The property was almost written off because a developer supposedly offered more than I did. Now I have received a call from the agent that the developer backed out three days before the notary appointment and my bid is now the highest. They asked if I still want to buy.....

I would like to build there; everything seems to fit. One probably doesn’t have to worry about the soakaway pit, as was written here. I spoke with neighbors; no one knows of any problems with the soil. The only thing I notice is that the property is not flat but partially hilly. It is also interesting whether there is a chance to keep the large beautiful tree at the front of the property or whether, due to the roots, there is rather no chance or if it is advisable not to keep it?











So, calmly buy and then find a suitable general contractor who will build there for us? Or definitely send out a geologist or the like before the notary appointment and first go into cost in advance?

What would be a suitable process from your point of view to concretize the whole thing? Appraisal.... buy..... put together a general contractor and a suitable offer..... then implement financing (property with existing building can theoretically be financed without external funds)? Or request a complete financing with corresponding equity and only when that is in place start looking for a building partner and only then go to the notary?

I have a simple building proposal including cost estimate from a general contractor. But I think that is not very reliable since no joint visit to the property took place in the past due to the non-binding nature. That is certainly mandatory before a notary appointment or how do you see it?

I have already had the financing and thus my budget calculated when I last dealt with this property.
