Rainwater must be obligatorily infiltrated

I am always amazed at all the things money is spent on during construction. But heaven forbid 5m2 more living space or the floor covering costs 35 instead of 25€/m2

I am also amazed at the conclusions you draw, as if you had been there yourself.... Calculate sensibly, then there will be no nasty surprise for you either.

Guys, you always imagine it so simply, "excavator for a hundred bucks" etc... believe me, we also have such a "candidate" here,
there everything is in chaos because everything is supposed to run better/cheaper on your own supposedly.
I prefer to plan more generously from the start and thus experience no surprises and have an invoice and warranty for everything.

It starts with digging the hole - do you bring the 5 double-axle loads of soil to the landfill?
Do you assemble the infiltration trench professionally - you get it in individual parts to put together!
I can reassure you, it was neither done by us with 2 men in 2 days, nor by the neighbors with their civil engineers!

It was about the 35 m supply line here. It doesn't even have to be frost-free, you can even dig it by hand. And there isn't really much excavation. You spread it on the property.

But to each their own. I would feel sorry about the money.

That was a complete package with driveway and infiltration trench and terrace etc., these 35 meters were laid crisscross, also under the paving,
so for me as a layman, somewhat more complex and not feasible due to lack of machinery and experience.
But to draw conclusions from that that one would complain elsewhere, I find misplaced here.

My available time alone would never allow the project!

People, you always imagine it so easy, "excavator for a hundred bucks" etc... believe me, we also have such a "candidate" here, over there everything is chaotic because everything is supposed to be done better/cheaper in presumed self-management. I prefer to plan more generously from the start and thus avoid surprises and have an invoice and warranty for everything.

It starts with digging the hole - do you bring the five double-axle loads of soil to the landfill? Do you assemble the infiltration trench professionally - you get it in single parts to put together! I can reassure you, it was not done by us with 2 men in 2 days, nor by the neighbors’ civil engineers!

Yeah, I actually did that back then. But my father also has tractors and an 18-ton trailer. That’s not supposed to be the standard here. Do you think the construction worker makes a science out of everything? Sometimes you can be glad if the slope runs in the right direction....

The thing with the regulation of your infiltration trench is annoying, because it’s expensive. I was allowed to solve that differently at my place. Although I had a sizing for the infiltration trench from the architect, I optimized it for my geothermal heat pump and solved it differently.

But you also have to be keen on it. Otherwise you can only try to get good contacts through friends and neighbors. Or compare offers. I always call for larger trades and make an on-site appointment for discussion. Most offers were then fair and on equal terms.

For the house + driveway, removing 500m2 of topsoil, 300 tons of fill sand for backfilling cost me 3.5k back then (2020). I then temporarily stored 60m3 of topsoil 2 km away... it’s still there today.

But you also have to be into it.

Yeah, you have different conditions if family members have the machines, then they usually also have the knowledge. I, on the other hand, come from the other sector, the one that can/has to pay "these people" (without demeaning!!) which is not a problem at all. "We" (incompetent) must also exist so that the professionals can survive!

Regarding prices: 100-120 €/meter for laying KG pipe is within the same price range among 4 different contractors (from landscape gardeners to civil engineers).

On the topic of being into it:
Sure, I would like to leave something to my children that I personally worked on, but as already mentioned, if the time, machines, and expertise are missing, I won’t start trying to do something by brute force.

With us last autumn 43 EUR net / m. But then immediately KG 2000. I wouldn't have thought that [Köln] is so much more expensive than [Berlin].
