I'm planning on redoing the flooring in a basement room which has a concrete slab in a 1974 Seattle house. The current carpet, which I've already removed, will be replaced with LVP.
After removing the carpet, I spotted a bunch of loose concrete around the edges of two exterior walls (it's a corner room). It appears that the previous owners tried to originally nail down the tack strips for the carpet too close to the edge of the concrete slab which must have resulted in it getting chipped off in large chunks. I've cleaned out the loose concrete but I'm now left with multiple large holes (as large as 1" x 3"). Any ideas on how I can fix these?
From what I've researched so far, I want to ensure that the expansion gap between the foundation and the concrete slab remains untouched.
