I took out the partition walls in the basement of my 1923 house and the bottom sill plates were set into the concrete. With the wood removed (some of it basically disintegrated) I’ve now got some 1” deep 4” wide trenches in the concrete to deal with. It feels like concrete at the bottom, but maybe some dirt in spots.
The concrete was raised on either side of the sill like it had been poured against the wood. I’ve been chipping at the concrete to try to remove the high spots, but I wonder if I should try to cut them out instead. Do I need to go a certain depth?
Any insight into how I should patch them so I can extend the linoleum tiles over the area?
