Moisture in neighbor's garage, bubble wrap with or without fleece?

Hello everyone,
we have the following situation: There is a height difference between our neighbors and our property. As a result, we piled soil from our garden against their garage. This was done by our landscape gardener, who only used a dimpled membrane to protect the garage wall. After 4 years, a moisture damage appeared along the entire length of the garage in the neighbor’s garage at about 5 cm above the floor level. Until then, apparently only the base sealing of the garage had been done. The landscape gardener did not see the fault with himself, as the neighbors should have sealed the garage higher because they must have known that the neighboring property is higher, etc. but that is not what this is about now. We have now excavated a trench and applied a bitumen layer to the garage façade and had a cove installed at the bottom.

Now we would like to refill and have the following questions: 1. Is a renewed dimpled membrane sufficient in addition to the bitumen layer and the cove? If yes. 2. In which direction should the dimples face? Apparently there are advantages both ways. My tendency would be to have the dimples face the garage side so that ventilation of the wall can take place behind it. 3. Would a dimpled membrane with fleece provide additional security?

I would be very happy to receive a few tips.

Thank you very much in advance.

I will provide photos tomorrow.

hm, nobody has an idea? Or am I in the wrong forum section here? ;o)

Here at least are the mentioned photos.

Look up Bauhandwerk Where to put the protrusion.

"For this reason, on pressure-sensitive seals, drainage sheets with sliding, protective, and load distribution layers must generally be used to prevent the indentation of the seal and the associated consequential damage. [...] Drainage sheets with sliding, protective, and load distribution layers are laid with the protective and sliding layer on the seal. The filter fleece therefore also faces the soil here."

Thank you for the response. Just to make sure I understand correctly: Since the coating on the garage was a liquid-applied bitumen layer, I therefore need a 3-layer dimpled membrane in order not to damage this layer?

Did the neighbor give you permission to fill up against his garage? Did you alter the terrain or your neighbor?

Thank you very much for the answer. Just to make sure I understand correctly: Since the coating on the garage was a liquid-applied bitumen layer, do I now need a 3-layer dimpled membrane in order not to damage this layer?

That's how I would interpret it, yes. And I would rather play it safe anyway. For 20 sqm, it's a difference of less than 100 euros. It would be worth it to me, especially if I had already caused damage at the neighbor's...
