Hi. We have a house built in 1830 and the basement still has it's original dirt floor (How charming!). It's only about 5' high down there, and we were wondering if it was worth digging out and concreting over. It's about 15'x 40' and would have to be dug out about 3' or so. The dirt would have to be conveyed out and into a truck for removal. Someone suggested raising the house and adding more foundation.........but I don't know about that one! It's on a mortared stone foundation, which is about 5' high. I live in NJ, if that matters. We're thinking of adding on and thought about digging a basement for the new addition. Just wondering what a thing like that may cost. Thanks.
