I would like to dig out the crawl space in my home. The crawl space is next to the full basement and under my family room. There is approximately 3' of block around the sides now. I would like to dig it out to the grade of the rest of the basement. I would like to block in the rest of the walls and put in a concrete floor. Would I need to shore up the walls of the crawl space while digging out the dirt? Does anybody have any plans for such a project or done this project? I would like to do most of the project myself. Thanks in advance for any help.
