Sealing transition between ground slab and wall to the soil

Since my links were unfortunately removed, here is the additional information: There are simple studded membranes and 3-layer ones with foil + fleece. The question now is: Which of the two are necessary or recommended? Regards Kili

Search for: Bauhandwerk Noppenbahnen fachgerecht verlegen. It basically says everything in there. I guess: You need a fleece.

I had included exactly the link to the document in the first post and it was deleted. Exactly - because it states there that you should work with fleece when dealing with Bitumen. Thank you for your feedback

I also have a dimpled membrane with fleece. The fleece goes against the adjacent soil/backfilled material. The dimples also face this direction, away from the structure. I applied a black waterproofing layer to the area at the building and then installed the dimpled membrane with fleece. Then backfilled. On the weather side, small gutters will be added at the terrace level. At the terrace base towards the lawn, I am installing a linear drainage system. If you look up the brochure "AC* Master Drainage," you will find a picture that is structured like yours.

Cool thanks - I actually found exactly such a drawing with cove molding etc. I will then also install a 3-layer dimpled membrane with foil at the back and fleece at the front. Thanks to everyone for the help.

Hello everyone,

I would like to revisit this topic to briefly discuss something fundamental.

In advance:
We also have a construction project without a basement. The soil is very clayey and not permeable.
The concrete slab (depth approx. 80 cm + 6 cm insulation) contains perimeter insulation beneath it, a drainage pipe combined with a dimpled membrane would be the homeowner’s own work.

The site manager now thinks that drainage would be rather disadvantageous because it would create a water gradient. And that the waterproof concrete in the wet clay soil is not a problem.

Now I would like to get at least a second opinion, since I naturally want to have a foundation that is as stable as possible in the long term.
Can drainage in clay soil also be disadvantageous? Or am I not doing anything wrong by installing drainage all around the concrete slab?

Thanks in advance for your advice.
Best regards
Thomas
