Excavating around foundation to repair, address moisture issues ... risky?
My old clay block foundation walls have some issues - bowing in a little bit, crumbling mortar, some holes in the blocks. A complete foundation replacement would be a huge expense.
Is it possible to excavate around the outside of the foundation to repair the bowing walls and run some drain tiles along the outside (drain to daylight or a sump pump)?
My basement floor is a mess. It's thin and cracking. One basement contractor didn't even want to install a sump pump in my basement without first replacing the floor with a stronger, thicker slab. This of course would reduce the clearance making it about impossible to even walk down there (it's just over 6 feet now, and i'm 6'1).
Would my best bet be hiring an engineer to advise me on what I should do? I feel like if I spend the money repointing the foundation or straightening the walls with braces, it may not be the best long-term solution. What do you think?
