Hello,
we have a house without a basement, but with very clayey soil, the water drains very slowly. We now want to build a drainage system to protect the strip foundations and avoid "overflowing" water. The strip foundations are about 100cm below the top edge of the floor slab. We will also raise the soil to this height.
Attached is a picture with the heights I have in mind.
Further questions that remain:
- Is perimeter insulation around the foundations additionally useful?
- If yes, does it have to be tightly coated with bitumen paint?
- Can I let the rain gutters drain directly into the drainage system?
