Hello all, this is my first post. I have an issue... the block foundation/basement wall around my house is starting to crumble here and there and leaving craters on the external surface. For reference, the home was built in the early/mid 50's and these craters were there when I bought it last September... I imagine that they have been there for awhile. Here is a pic: I would like to know a long-term solution for filling in these craters. I want to repaint the wall once they are filled. The wall already does have paint on it and I am not sure if I need to remove the existing paint first or not. I am new to the home repair game, and everything I have researched about the issue so far has left me unsatisfied and I still cannot decide what plan of action to take. And help/advice is appreciated.
