I have a 1954 built house with a cinder block crawlspace foundation with about a 1 1/2 foot clearance. I can squeeze in, but not easily. I'm in Cleveland, OH, so there is definitely a freeze-thaw cycle.
I was crawling around looking for the source of a moldy smell, and found that one of the cinder blocks under our renovated kitchen was shattered.
My question is what is the best way to fix this - various masons have suggested filling the space with hydraulic cement with maybe some bricks tossed in for good measure to fill the void.
My thought was to grind the broken block out and "butter" in a new block.
What is the best way?
