Hello,
the subject title may be a bit confusing, so I will try to untangle the mess a bit:
We have an extension on the main building with moisture problems and a large outbuilding with mostly exposed roof drainage. The moisture problems stem from the fact that the ground covering outside between both buildings was raised so much that the rainwater presses directly between the two horizontal barriers. A seal in the form of a thick bitumen coating is not really present - more on that upon request.
Since the rainwater pipes currently empty centrally under the terrace into an old well, I want to redirect them into a soakaway basin far away from the house.
For this, of course, new KG pipes need to be laid - and here I come to the actual problem:
The yard is paved with grass grid stones - about 200 sqm of it. Underneath is about 30 cm of topsoil. Below that is the ORIGINAL path - paved with fieldstones (10-15 cm).
Below that again is topsoil, then comes heavily clayey soil.
My question is: if I now dig up, the pipe should be laid in gravel. My wife would like me to use the excavated soil - but here I see problems with settling. What is your opinion?
Second question:
Would it make sense to remove the soil to the secondary level, meaning down to the fieldstone base? Then it would make sense to first remove the soil and then lay the pipe under the pavement - I estimate about 60-80 cm deep. Your opinion on this?
Unfortunately, the previous owner of our house was completely foolish. He simply clad the base of our bedroom outside with fieldstone slabs and then built up the ground outside by 30 cm. Although the edges of the fieldstones are grouted, we still have moisture and mold formation exactly up to the second horizontal barrier in the room.
For me as a layman, it would seem obvious to restore the original condition after construction so that rainwater does not come over the base at all. Additionally, a drainpipe (coconut) will also be laid.
Your opinions are very important to me. We are not super rich. The previous repairs were all necessary due to the previous owner's negligence, previously not visible and are straining the budget.
Best regards - Maik
