I recently have moved into a place that has a reasonably sized basement, the problem is the house is at least 80-90 years old. The basement has a very thin concrete siding, (.1" - .2") and it is completely falling off. There are large areas / patches where you can see the Rock / Red dirt, and the problem is red dirt is falling on pretty much anything near it, and building up in piles on the side.
So, how would I go about fixing that? It was clearly not done well in the first place, and is very uneven overall. What would be the best way to get a smooth concrete layer on the side as it is now?
Thank you!
