Shield against water veins and earth rays

Hello,
I don’t know if I am in the right forum here. Unfortunately, I didn’t find anything using the search function.
We have a plot of land that we want to build on, but it only has a small buildable area. As far as rough investigation shows, several water veins run through our house and there are additional interference fields caused by earth radiation.
Is there a way to shield the sources of interference? One company wanted to sell us a concrete slab with metal shavings, which is supposed to shield the earth radiation. Does anyone here have experience with this? Who can give me further tips? Another plot unfortunately is not an option.
I didn’t believe in such things for a long time, only because of an acquaintance who became ill due to water veins. As a result, we had someone loosely examine the plot with a dowsing rod. But I only really started to believe it after a second dowser located water veins in the same spots without knowing about the first.
Now we are somewhat unsettled and are already trying to shield everything under the floor slab, if there is anything to it.

Hello,

please first inquire about how dowsing rods work. They only function during a full moon. If dangerous water veins are actually found, the best way to combat them is with fire.

No, okay, just kidding: You are better off with this request in an esotericism forum. Dowsing rods are far from any science and only "work" through imagination. The same applies to the danger of water veins... It will not be possible for you to definitively attribute an acquaintance’s illness to a water vein (unless they fell in and drowned...) If you actually can do that... Congratulations on your next Nobel Prize.

OBJECTION... I also tried that once during my internship with a copper wire. And it worked even for me, I walked across a meadow with the wire and the knowledge that it was total nonsense - and the thing reacted - and exactly at that spot was the channel under the meadow. Several times from different directions at various spots. We had plans (which I had not seen before!) however, I do not believe in esoteric stuff, like evil effects and strange radiation

How does a dowsing rod behave near underfloor heating or a waterbed?

*lol no idea, I haven't stepped over one yet
I also don't want to discuss the sense and nonsense of the whole thing,
of course there is no scientific evidence for it, I only pointed out, even at the risk of making myself ridiculous, that it worked in this one case on that meadow.
Where the channel was, I didn't know, so nothing with moving it unconsciously myself. I was surprised myself, because I believe neither in God nor any other "supernatural things," I'm way too scientifically minded for that.
I won't justify myself any further,
@Frosch: this is certainly not the right forum for such a request

Are you sure that you want to block [Erdstrahlen]? I have a construction performance description from an eco-architect, and it says that one should avoid using iron in the floor slab as much as possible in order not to interfere with the natural radiation field.... I would say that one of you two has misunderstood something.
