ᐅ Wall absorbs moisture (strip foundation garage without basement)

Hello everyone,
As you can see in the pictures, there is already damage on one wall side in the garage (rising damp and plaster crumbling).
I believe this is because the concrete wedge of the perimeter strips on the outside runs directly up to the house wall (visible in pictures 4 and 5). Water cannot drain here.
At this spot, the rain doesn’t reach due to the roof overhang, and everything above the concrete wedge was dry. Only below it was damp. I have now removed a good portion of the wedge so that water can drain away and the ground underneath can dry out. But how should I treat the masonry? Waterproof slurry and drainage membrane?
Do you think that with the now shortened wedge, this will work permanently?
Best regards,
Tom

I just found a photo taken from outside. This is basically how the entire exterior of the garage looked.
As mentioned, the waterproof slurry must be applied all the way into the junction between the wall and the strip foundation. Otherwise, water always finds its way through the concrete.
