I need to remove 2 concrete blocks so i can add 2 crawl space vents 14 feet apart. Not knowing much about concrete blocks i can only tell you there are 8 blocks laying in the crawl space that must have been extras and they each have 2 hollow spaces in them so i'll assume that is where you would put concrete . These blocks are maybe 16.
Question is how do i remove these blocks. I'll assume chisel around the mortar and tap with a hand sledgehammer.
