The house was built in 1931 so could be real cinder blocks. That block is also right in front of a gutter.
Can a do it yourself we remove and replace the block?
How do I know if below grade blocks were waterproofed?
I have some spalling on my block foundation. Most of the blocks have about a half inch of spalling but one near the gutter has 2 3" diameter holes. See picture. Is this something I can just parge over or do I need to do more to bolster the structural integrity of the crumbling block?
