I have missed this during the years I've lived in the house, but recently, read months, I've started to worry a bit about a crack in an exterior wall in the basement. I was down there tapping on it a bit today and managed to loosen the entire joint between the stones. The house is from -52, so I have no idea what material it is built with, it's thick anyway. It looks like it has been patched before as the length of the crack is darker than the rest of the wall.
Haven't measured exactly but the outside of the basement stairs, the inner corner is there. Otherwise, it's nothing more than soil and gravel on it. It's one of the outer corners of the house.
The drainage is something I haven't really done anything about, except that all vegetation is gone and replaced by a few decimeters of gravel instead. I live on top of a hill and have never really seen the need to redo the drainage as it isn't visible anywhere. I don't know how long it has looked like that, but it's been a while. There was a huge oil tank there until a few years ago when I replaced the boiler.
Digging outside now and it's right in the inner corner of the basement stairs. It's also cracked on the exterior. The big hole inside is right in the corner outside.
Now I've chipped away everything inside that was loose. It was repaired sometime earlier with completely wrong mortar. It's something dark and rock-hard, so I understand why it cracked. The question is mostly if it was a long time ago, which I assume since I haven't repaired it, and when I moved in there was a large oil tank there.
